(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

that is based on (or derived from) the Work and for which the editorial revisions,
annotations, elaborations, or other modifications represent, as a whole, an
original work of authorship. For the purposes of this License, Derivative
Works shall not include works that remain separable from, or merely link (or
bind by name) to the interfaces of, the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including the original version
of the Work and any modifications or additions to that Work or Derivative
Works thereof, that is intentionally submitted to Licensor for inclusion in
the Work by the copyright owner or by an individual or Legal Entity authorized
to submit on behalf of the copyright owner. For the purposes of this definition,
"submitted" means any form of electronic, verbal, or written communication
sent to the Licensor or its representatives, including but not limited to
communication on electronic mailing lists, source code control systems, and
issue tracking systems that are managed by, or on behalf of, the Licensor
for the purpose of discussing and improving the Work, but excluding communication
that is conspicuously marked or otherwise designated in writing by the copyright
owner as "Not a Contribution."
"Contributor" shall mean Licensor and any individual or Legal Entity on behalf
of whom a Contribution has been received by Licensor and subsequently incorporated
within the Work.
2. Grant of Copyright License. Subject to the terms and conditions of this
License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive,
no-charge, royalty-free, irrevocable copyright license to reproduce, prepare
Derivative Works of, publicly display, publicly perform, sublicense, and distribute
the Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of this License,
each Contributor hereby grants to You a perpetual, worldwide, non-exclusive,
no-charge, royalty-free, irrevocable (except as stated in this section) patent
license to make, have made, use, offer to sell, sell, import, and otherwise
transfer the Work, where such license applies only to those patent claims
licensable by such Contributor that are necessarily infringed by their Contribution(s)
alone or by combination of their Contribution(s) with the Work to which such
Contribution(s) was submitted. If You institute patent litigation against
any entity (including a cross-claim or counterclaim in a lawsuit) alleging
that the Work or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses granted to You
under this License for that Work shall terminate as of the date such litigation
is filed.
4. Redistribution. You may reproduce and distribute copies of the Work or
Derivative Works thereof in any medium, with or without modifications, and
in Source or Object form, provided that You meet the following conditions:
(a) You must give any other recipients of the Work or Derivative Works a copy
of this License; and
(b) You must cause any modified files to carry prominent notices stating that
You changed the files; and
(c) You must retain, in the Source form of any Derivative Works that You distribute,
all copyright, patent, trademark, and attribution notices from the Source
form of the Work, excluding those notices that do not pertain to any part
of the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its distribution,
then any Derivative Works that You distribute must include a readable copy
of the attribution notices contained within such NOTICE file, excluding those
notices that do not pertain to any part of the Derivative Works, in at least
one of the following places: within a NOTICE text file distributed as part
of the Derivative Works; within the Source form or documentation, if provided
along with the Derivative Works; or, within a display generated by the Derivative
Works, if and wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and do not modify the
License. You may add Your own attribution notices within Derivative Works
that You distribute, alongside or as an addendum to the NOTICE text from the
Work, provided that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and may provide
additional or different license terms and conditions for use, reproduction,
or distribution of Your modifications, or for any such Derivative Works as
a whole, provided Your use, reproduction, and distribution of the Work otherwise
complies with the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise, any
Contribution intentionally submitted for inclusion in the Work by You to the
Licensor shall be under the terms and conditions of this License, without
any additional terms or conditions. Notwithstanding the above, nothing herein
shall supersede or modify the terms of any separate license agreement you
may have executed with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade names,
trademarks, service marks, or product names of the Licensor, except as required
for reasonable and customary use in describing the origin of the Work and
reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or agreed to
in writing, Licensor provides the Work (and each Contributor provides its
Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
KIND, either express or implied, including, without limitation, any warranties
or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR
A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness
of using or redistributing the Work and assume any risks associated with Your
exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory, whether
in tort (including negligence), contract, or otherwise, unless required by
applicable law (such as deliberate and grossly negligent acts) or agreed to
in writing, shall any Contributor be liable to You for damages, including
any direct, indirect, special, incidental, or consequential damages of any
character arising as a result of this License or out of the use or inability
to use the Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all other commercial
damages or losses), even if such Contributor has been advised of the possibility
of such damages.
9. Accepting Warranty or Additional Liability. While redistributing the Work
or Derivative Works thereof, You may choose to offer, and charge a fee for,
acceptance of support, warranty, indemnity, or other liability obligations
and/or rights consistent with this License. However, in accepting such obligations,
You may act only on Your own behalf and on Your sole responsibility, not on
behalf of any other Contributor, and only if You agree to indemnify, defend,
and hold each Contributor harmless for any liability incurred by, or claims
asserted against, such Contributor by reason of your accepting any such warranty
or additional liability. END OF TERMS AND CONDITIONS

Using Creative Commons Public Licenses
Creative Commons public licenses provide a standard set of terms and conditions
that creators and other rights holders may use to share original works of
authorship and other material subject to copyright and certain other rights
specified in the public license below. The following considerations are for
informational purposes only, are not exhaustive, and do not form part of our
licenses.
Considerations for licensors: Our public licenses are intended for use by
those authorized to give the public permission to use material in ways otherwise
restricted by copyright and certain other rights. Our licenses are irrevocable.
Licensors should read and understand the terms and conditions of the license
they choose before applying it. Licensors should also secure all rights necessary
before applying our licenses so that the public can reuse the material as
expected. Licensors should clearly mark any material not subject to the license.
This includes other CC-licensed material, or material used under an exception
or limitation to copyright. More considerations for licensors : wiki.creativecommons.org/Considerations_for_licensors
Considerations for the public: By using one of our public licenses, a licensor
grants the public permission to use the licensed material under specified
terms and conditions. If the licensor's permission is not necessary for any
reason–for example, because of any applicable exception or limitation to copyright–then
that use is not regulated by the license. Our licenses grant only permissions
under copyright and certain other rights that a licensor has authority to
grant. Use of the licensed material may still be restricted for other reasons,
including because others have copyright or other rights in the material. A
licensor may make special requests, such as asking that all changes be marked
or described. Although not required by our licenses, you are encouraged to
respect those requests where reasonable. More considerations for the public
: wiki.creativecommons.org/Considerations_for_licensees Creative Commons Attribution
4.0 International Public License
By exercising the Licensed Rights (defined below), You accept and agree to
be bound by the terms and conditions of this Creative Commons Attribution
4.0 International Public License ("Public License"). To the extent this Public
License may be interpreted as a contract, You are granted the Licensed Rights
in consideration of Your acceptance of these terms and conditions, and the
Licensor grants You such rights in consideration of benefits the Licensor
receives from making the Licensed Material available under these terms and
conditions.
Section 1 – Definitions.
a. Adapted Material means material subject to Copyright and Similar Rights
that is derived from or based upon the Licensed Material and in which the
Licensed Material is translated, altered, arranged, transformed, or otherwise
modified in a manner requiring permission under the Copyright and Similar
Rights held by the Licensor. For purposes of this Public License, where the
Licensed Material is a musical work, performance, or sound recording, Adapted
Material is always produced where the Licensed Material is synched in timed
relation with a moving image.
b. Adapter's License means the license You apply to Your Copyright and Similar
Rights in Your contributions to Adapted Material in accordance with the terms
and conditions of this Public License.
c. Copyright and Similar Rights means copyright and/or similar rights closely
related to copyright including, without limitation, performance, broadcast,
sound recording, and Sui Generis Database Rights, without regard to how the
rights are labeled or categorized. For purposes of this Public License, the
rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
d. Effective Technological Measures means those measures that, in the absence
of proper authority, may not be circumvented under laws fulfilling obligations
under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996,
and/or similar international agreements.
e. Exceptions and Limitations means fair use, fair dealing, and/or any other
exception or limitation to Copyright and Similar Rights that applies to Your
use of the Licensed Material.
f. Licensed Material means the artistic or literary work, database, or other
material to which the Licensor applied this Public License.
g. Licensed Rights means the rights granted to You subject to the terms and
conditions of this Public License, which are limited to all Copyright and
Similar Rights that apply to Your use of the Licensed Material and that the
Licensor has authority to license.
h. Licensor means the individual(s) or entity(ies) granting rights under this
Public License.
i. Share means to provide material to the public by any means or process that
requires permission under the Licensed Rights, such as reproduction, public
display, public performance, distribution, dissemination, communication, or
importation, and to make material available to the public including in ways
that members of the public may access the material from a place and at a time
individually chosen by them.
j. Sui Generis Database Rights means rights other than copyright resulting
from Directive 96/9/EC of the European Parliament and of the Council of 11
March 1996 on the legal protection of databases, as amended and/or succeeded,
as well as other essentially equivalent rights anywhere in the world.
k. You means the individual or entity exercising the Licensed Rights under
this Public License. Your has a corresponding meaning.
Section 2 – Scope.
a. License grant.
1. Subject to the terms and conditions of this Public License, the Licensor
hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive,
irrevocable license to exercise the Licensed Rights in the Licensed Material
to:
A. reproduce and Share the Licensed Material, in whole or in part; and
B. produce, reproduce, and Share Adapted Material.
2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions
and Limitations apply to Your use, this Public License does not apply, and
You do not need to comply with its terms and conditions.
3. Term. The term of this Public License is specified in Section 6(a).
4. Media and formats; technical modifications allowed. The Licensor authorizes
You to exercise the Licensed Rights in all media and formats whether now known
or hereafter created, and to make technical modifications necessary to do
so. The Licensor waives and/or agrees not to assert any right or authority
to forbid You from making technical modifications necessary to exercise the
Licensed Rights, including technical modifications necessary to circumvent
Effective Technological Measures. For purposes of this Public License, simply
making modifications authorized by this Section 2(a)(4) never produces Adapted
Material.
5. Downstream recipients.
A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed
Material automatically receives an offer from the Licensor to exercise the
Licensed Rights under the terms and conditions of this Public License.
B. No downstream restrictions. You may not offer or impose any additional
or different terms or conditions on, or apply any Effective Technological
Measures to, the Licensed Material if doing so restricts exercise of the Licensed
Rights by any recipient of the Licensed Material.
6. No endorsement. Nothing in this Public License constitutes or may be construed
as permission to assert or imply that You are, or that Your use of the Licensed
Material is, connected with, or sponsored, endorsed, or granted official status
by, the Licensor or others designated to receive attribution as provided in
Section 3(a)(1)(A)(i).
b. Other rights.
1. Moral rights, such as the right of integrity, are not licensed under this
Public License, nor are publicity, privacy, and/or other similar personality
rights; however, to the extent possible, the Licensor waives and/or agrees
not to assert any such rights held by the Licensor to the limited extent necessary
to allow You to exercise the Licensed Rights, but not otherwise.
2. Patent and trademark rights are not licensed under this Public License.
3. To the extent possible, the Licensor waives any right to collect royalties
from You for the exercise of the Licensed Rights, whether directly or through
a collecting society under any voluntary or waivable statutory or compulsory
licensing scheme. In all other cases the Licensor expressly reserves any right
to collect such royalties.
Section 3 – License Conditions.
Your exercise of the Licensed Rights is expressly made subject to the following
conditions.
a. Attribution.
1. If You Share the Licensed Material (including in modified form), You must:
A. retain the following if it is supplied by the Licensor with the Licensed
Material:
i. identification of the creator(s) of the Licensed Material and any others
designated to receive attribution, in any reasonable manner requested by the
Licensor (including by pseudonym if designated);
ii. a copyright notice;
iii. a notice that refers to this Public License;
iv. a notice that refers to the disclaimer of warranties;
v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;
B. indicate if You modified the Licensed Material and retain an indication
of any previous modifications; and
C. indicate the Licensed Material is licensed under this Public License, and
include the text of, or the URI or hyperlink to, this Public License.
2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner
based on the medium, means, and context in which You Share the Licensed Material.
For example, it may be reasonable to satisfy the conditions by providing a
URI or hyperlink to a resource that includes the required information.
3. If requested by the Licensor, You must remove any of the information required
by Section 3(a)(1)(A) to the extent reasonably practicable.
4. If You Share Adapted Material You produce, the Adapter's License You apply
must not prevent recipients of the Adapted Material from complying with this
Public License.
Section 4 – Sui Generis Database Rights.
Where the Licensed Rights include Sui Generis Database Rights that apply to
Your use of the Licensed Material:
a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
reuse, reproduce, and Share all or a substantial portion of the contents of
the database;
b. if You include all or a substantial portion of the database contents in
a database in which You have Sui Generis Database Rights, then the database
in which You have Sui Generis Database Rights (but not its individual contents)
is Adapted Material; and
c. You must comply with the conditions in Section 3(a) if You Share all or
a substantial portion of the contents of the database.
For the avoidance of doubt, this Section 4 supplements and does not replace
Your obligations under this Public License where the Licensed Rights include
other Copyright and Similar Rights.
Section 5 – Disclaimer of Warranties and Limitation of Liability.
a. Unless otherwise separately undertaken by the Licensor, to the extent possible,
the Licensor offers the Licensed Material as-is and as-available, and makes
no representations or warranties of any kind concerning the Licensed Material,
whether express, implied, statutory, or other. This includes, without limitation,
warranties of title, merchantability, fitness for a particular purpose, non-infringement,
absence of latent or other defects, accuracy, or the presence or absence of
errors, whether or not known or discoverable. Where disclaimers of warranties
are not allowed in full or in part, this disclaimer may not apply to You.
b. To the extent possible, in no event will the Licensor be liable to You
on any legal theory (including, without limitation, negligence) or otherwise
for any direct, special, indirect, incidental, consequential, punitive, exemplary,
or other losses, costs, expenses, or damages arising out of this Public License
or use of the Licensed Material, even if the Licensor has been advised of
the possibility of such losses, costs, expenses, or damages. Where a limitation
of liability is not allowed in full or in part, this limitation may not apply
to You.
c. The disclaimer of warranties and limitation of liability provided above
shall be interpreted in a manner that, to the extent possible, most closely
approximates an absolute disclaimer and waiver of all liability.
Section 6 – Term and Termination.
a. This Public License applies for the term of the Copyright and Similar Rights
licensed here. However, if You fail to comply with this Public License, then
Your rights under this Public License terminate automatically.
b. Where Your right to use the Licensed Material has terminated under Section
6(a), it reinstates:
1. automatically as of the date the violation is cured, provided it is cured
within 30 days of Your discovery of the violation; or
2. upon express reinstatement by the Licensor.
c. For the avoidance of doubt, this Section 6(b) does not affect any right
the Licensor may have to seek remedies for Your violations of this Public
License.
d. For the avoidance of doubt, the Licensor may also offer the Licensed Material
under separate terms or conditions or stop distributing the Licensed Material
at any time; however, doing so will not terminate this Public License.
e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
Section 7 – Other Terms and Conditions.
a. The Licensor shall not be bound by any additional or different terms or
conditions communicated by You unless expressly agreed.
b. Any arrangements, understandings, or agreements regarding the Licensed
Material not stated herein are separate from and independent of the terms
and conditions of this Public License.
Section 8 – Interpretation.
a. For the avoidance of doubt, this Public License does not, and shall not
be interpreted to, reduce, limit, restrict, or impose conditions on any use
of the Licensed Material that could lawfully be made without permission under
this Public License.
b. To the extent possible, if any provision of this Public License is deemed
unenforceable, it shall be automatically reformed to the minimum extent necessary
to make it enforceable. If the provision cannot be reformed, it shall be severed
from this Public License without affecting the enforceability of the remaining
terms and conditions.
c. No term or condition of this Public License will be waived and no failure
to comply consented to unless expressly agreed to by the Licensor.
d. Nothing in this Public License constitutes or may be interpreted as a limitation
upon, or waiver of, any privileges and immunities that apply to the Licensor
or You, including from the legal processes of any jurisdiction or authority.

# SPIRV-Cross
SPIRV-Cross is a tool designed for parsing and converting SPIR-V to other shader languages.
[![CI](https://github.com/KhronosGroup/SPIRV-Cross/actions/workflows/main.yml/badge.svg)](https://github.com/KhronosGroup/SPIRV-Cross/actions/workflows/main.yml)
[![Build Status](https://ci.appveyor.com/api/projects/status/github/KhronosGroup/SPIRV-Cross?svg=true&branch=main)](https://ci.appveyor.com/project/HansKristian-Work/SPIRV-Cross)
## Features
- Convert SPIR-V to readable, usable and efficient GLSL
- Convert SPIR-V to readable, usable and efficient Metal Shading Language (MSL)
- Convert SPIR-V to readable, usable and efficient HLSL
- Convert SPIR-V to a JSON reflection format
- Convert SPIR-V to debuggable C++ [DEPRECATED]
- Reflection API to simplify the creation of Vulkan pipeline layouts
- Reflection API to modify and tweak OpDecorations
- Supports "all" of vertex, fragment, tessellation, geometry and compute shaders.
SPIRV-Cross tries hard to emit readable and clean output from the SPIR-V.
The goal is to emit GLSL or MSL that looks like it was written by a human and not awkward IR/assembly-like code.
NOTE: Individual features are expected to be mostly complete, but it is possible that certain obscure GLSL features are not yet supported.
However, most missing features are expected to be "trivial" improvements at this stage.
## Building
SPIRV-Cross has been tested on Linux, iOS/OSX, Windows and Android. CMake is the main build system.
### NOTE: main branch rename
On 2023-01-12, `master` was renamed to `main` as per Khronos policy.
### Linux and macOS
Building with CMake is recommended, as it is the only build system which is tested in continuous integration.
It is also the only build system which has install commands and other useful build system features.
However, you can just run `make` on the command line as a fallback if you only care about the CLI tool.
A non-ancient GCC (4.8+) or Clang (3.x+) compiler is required as SPIRV-Cross uses C++11 extensively.
### Windows
Building with CMake is recommended, which is the only way to target MSVC.
MinGW-w64 based compilation works with `make` as a fallback.
### Android
SPIRV-Cross is only useful as a library here. Use the CMake build to link SPIRV-Cross to your project.
### C++ exceptions
The make and CMake build flavors offer the option to treat exceptions as assertions. To disable exceptions for make just append `SPIRV_CROSS_EXCEPTIONS_TO_ASSERTIONS=1` to the command line. For CMake append `-DSPIRV_CROSS_EXCEPTIONS_TO_ASSERTIONS=ON`. By default exceptions are enabled.
### Static, shared and CLI
You can use `-DSPIRV_CROSS_STATIC=ON/OFF` `-DSPIRV_CROSS_SHARED=ON/OFF` `-DSPIRV_CROSS_CLI=ON/OFF` to control which modules are built (and installed).
### Installing SPIRV-Cross (vcpkg)
Alternatively, you can build and install SPIRV-Cross using [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:
```
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install spirv-cross
```
The SPIRV-Cross port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
## Usage
### Using the C++ API
The C++ API is the main API for SPIRV-Cross. For more in-depth documentation than what's provided in this README,
please have a look at the [Wiki](https://github.com/KhronosGroup/SPIRV-Cross/wiki).
**NOTE**: This API is not guaranteed to be ABI-stable, and it is highly recommended to link against this API statically.
The API is generally quite stable, but it can change over time, see the C API for more stability.
To perform reflection and convert to other shader languages you can use the SPIRV-Cross API.
For example:
```c++

### Using the C API wrapper
To facilitate C compatibility and compatibility with foreign programming languages, a C89-compatible API wrapper is provided. Unlike the C++ API,
the goal of this wrapper is to be fully stable, both API and ABI-wise.
This is the only interface which is supported when building SPIRV-Cross as a shared library.
An important point of the wrapper is that all memory allocations are contained in the `spvc_context`.
This simplifies the use of the API greatly. However, you should destroy the context as soon as reasonable,
or use `spvc_context_release_allocations()` if you intend to reuse the `spvc_context` object again soon.
Most functions return a `spvc_result`, where `SPVC_SUCCESS` is the only success code.
For brevity, the code below does not do any error checking.
```c
#include <spirv_cross_c.h>
const SpvId *spirv = get_spirv_data();
size_t word_count = get_spirv_word_count();
spvc_context context = NULL;
spvc_parsed_ir ir = NULL;
spvc_compiler compiler_glsl = NULL;
spvc_compiler_options options = NULL;
spvc_resources resources = NULL;
const spvc_reflected_resource *list = NULL;
const char *result = NULL;
size_t count;
size_t i;
// Create context.
spvc_context_create(&context);
// Set debug callback.
spvc_context_set_error_callback(context, error_callback, userdata);
// Parse the SPIR-V.
spvc_context_parse_spirv(context, spirv, word_count, &ir);
// Hand it off to a compiler instance and give it ownership of the IR.
spvc_context_create_compiler(context, SPVC_BACKEND_GLSL, ir, SPVC_CAPTURE_MODE_TAKE_OWNERSHIP, &compiler_glsl);
// Do some basic reflection.
spvc_compiler_create_shader_resources(compiler_glsl, &resources);
spvc_resources_get_resource_list_for_type(resources, SPVC_RESOURCE_TYPE_UNIFORM_BUFFER, &list, &count);
for (i = 0; i < count; i++)
{
printf("ID: %u, BaseTypeID: %u, TypeID: %u, Name: %s\n", list[i].id, list[i].base_type_id, list[i].type_id,
list[i].name);
printf(" Set: %u, Binding: %u\n",
spvc_compiler_get_decoration(compiler_glsl, list[i].id, SpvDecorationDescriptorSet),
spvc_compiler_get_decoration(compiler_glsl, list[i].id, SpvDecorationBinding));
}
// Modify options.
spvc_compiler_create_compiler_options(compiler_glsl, &options);
spvc_compiler_options_set_uint(options, SPVC_COMPILER_OPTION_GLSL_VERSION, 330);
spvc_compiler_options_set_bool(options, SPVC_COMPILER_OPTION_GLSL_ES, SPVC_FALSE);
spvc_compiler_install_compiler_options(compiler_glsl, options);
spvc_compiler_compile(compiler_glsl, &result);
printf("Cross-compiled source: %s\n", result);
// Frees all memory we allocated so far.
spvc_context_destroy(context);
```
### Linking
#### CMake add_subdirectory()
This is the recommended way if you are using CMake and want to link against SPIRV-Cross statically.
#### Integrating SPIRV-Cross in a custom build system
To add SPIRV-Cross to your own codebase, just copy the source and header files from root directory
and build the relevant .cpp files you need. Make sure to build with C++11 support, e.g. `-std=c++11` in GCC and Clang.
Alternatively, the Makefile generates a libspirv-cross.a static library during build that can be linked in.
#### Linking against SPIRV-Cross as a system library
It is possible to link against SPIRV-Cross when it is installed as a system library,
which would be mostly relevant for Unix-like platforms.
##### pkg-config
For Unix-based systems, a pkg-config is installed for the C API, e.g.:
```
$ pkg-config spirv-cross-c-shared --libs --cflags
-I/usr/local/include/spirv_cross -L/usr/local/lib -lspirv-cross-c-shared
```
##### CMake
If the project is installed, it can be found with `find_package()`, e.g.:
```
cmake_minimum_required(VERSION 3.5)
set(CMAKE_C_STANDARD 99)
project(Test LANGUAGES C)
find_package(spirv_cross_c_shared)
if (spirv_cross_c_shared_FOUND)
message(STATUS "Found SPIRV-Cross C API! :)")
else()
message(STATUS "Could not find SPIRV-Cross C API! :(")
endif()
add_executable(test test.c)
target_link_libraries(test spirv-cross-c-shared)
```
test.c:
```c
#include <spirv_cross_c.h>
int main(void)
{
spvc_context context;
spvc_context_create(&context);
spvc_context_destroy(context);
}
```
### CLI
The CLI is suitable for basic cross-compilation tasks, but it cannot support the full flexibility that the API can.
Some examples below.
#### Creating a SPIR-V file from GLSL with glslang
```
glslangValidator -H -V -o test.spv test.frag
```
#### Converting a SPIR-V file to GLSL ES
```
glslangValidator -H -V -o test.spv shaders/comp/basic.comp
./spirv-cross --version 310 --es test.spv
```
#### Converting to desktop GLSL
```
glslangValidator -H -V -o test.spv shaders/comp/basic.comp
./spirv-cross --version 330 --no-es test.spv --output test.comp
```
#### Disable prettifying optimizations
```
glslangValidator -H -V -o test.spv shaders/comp/basic.comp
./spirv-cross --version 310 --es test.spv --output test.comp --force-temporary
```
### Using shaders generated from C++ backend
Please see `samples/cpp` where some GLSL shaders are compiled to SPIR-V, decompiled to C++ and run with test data.
Reading through the samples should explain how to use the C++ interface.
A simple Makefile is included to build all shaders in the directory.
### Implementation notes
When using SPIR-V and SPIRV-Cross as an intermediate step for cross-compiling between high level languages there are some considerations to take into account,
as not all features used by one high-level language are necessarily supported natively by the target shader language.
SPIRV-Cross aims to provide the tools needed to handle these scenarios in a clean and robust way, but some manual action is required to maintain compatibility.
#### HLSL source to GLSL
##### HLSL entry points
When using SPIR-V shaders compiled from HLSL, there are some extra things you need to take care of.
First make sure that the entry point is used correctly.
If you forget to set the entry point correctly in glslangValidator (-e MyFancyEntryPoint),
you will likely encounter this error message:
```
Cannot end a function before ending the current block.
Likely cause: If this SPIR-V was created from glslang HLSL, make sure the entry point is valid.
```
##### Vertex/Fragment interface linking
HLSL relies on semantics in order to effectively link together shader stages. In the SPIR-V generated by glslang, the transformation from HLSL to GLSL ends up looking like
```c++
struct VSOutput {
// SV_Position is rerouted to gl_Position
float4 position : SV_Position;
float4 coord : TEXCOORD0;
};
VSOutput main(...) {}
```
```c++
struct VSOutput {
float4 coord;
}
layout(location = 0) out VSOutput _magicNameGeneratedByGlslang;
```
While this works, be aware of the type of the struct which is used in the vertex stage and the fragment stage.
There may be issues if the structure type name differs in vertex stage and fragment stage.
You can make use of the reflection interface to force the name of the struct type.
```
// Something like this for both vertex outputs and fragment inputs.
compiler.set_name(varying_resource.base_type_id, "VertexFragmentLinkage");
```
Some platform may require identical variable name for both vertex outputs and fragment inputs. (for example MacOSX)
to rename variable base on location, please add
```
--rename-interface-variable <in|out> <location> <new_variable_name>
```
#### HLSL source to legacy GLSL/ESSL
HLSL tends to emit varying struct types to pass data between vertex and fragment.
This is not supported in legacy GL/GLES targets, so to support this, varying structs are flattened.
This is done automatically, but the API user might need to be aware that this is happening in order to support all cases.
Modern GLES code like this:
```c++
struct Output {
vec4 a;
vec2 b;
};
out Output vout;
```
Is transformed into:
```c++
struct Output {
vec4 a;
vec2 b;
};
varying vec4 Output_a;
varying vec2 Output_b;
```
Note that now, both the struct name and the member names will participate in the linking interface between vertex and fragment, so
API users might want to ensure that both the struct names and member names match so that vertex outputs and fragment inputs can link properly.
#### Separate image samplers (HLSL/Vulkan) for backends which do not support it (GLSL)
Another thing you need to remember is when using samplers and textures in HLSL these are separable, and not directly compatible with GLSL. If you need to use this with desktop GL/GLES, you need to call `Compiler::build_combined_image_samplers` first before calling `Compiler::compile`, or you will get an exception.
```c++
// From main.cpp
// Builds a mapping for all combinations of images and samplers.
compiler->build_combined_image_samplers();
// Give the remapped combined samplers new names.
// Here you can also set up decorations if you want (binding = #N).
for (auto &remap : compiler->get_combined_image_samplers())
{
compiler->set_name(remap.combined_id, join("SPIRV_Cross_Combined", compiler->get_name(remap.image_id),
compiler->get_name(remap.sampler_id)));
}
```
If your target is Vulkan GLSL, `--vulkan-semantics` will emit separate image samplers as you'd expect.
The command line client calls `Compiler::build_combined_image_samplers` automatically, but if you're calling the library, you'll need to do this yourself.
#### Descriptor sets (Vulkan GLSL) for backends which do not support them (pre HLSL 5.1 / GLSL)
Descriptor sets are unique to Vulkan, so make sure that descriptor set + binding is remapped to a flat binding scheme (set always 0), so that other APIs can make sense of the bindings.
This can be done with `Compiler::set_decoration(id, spv::DecorationDescriptorSet)`. For other backends like MSL and HLSL, descriptor sets
can be used, with some minor caveats, see below.
##### MSL 2.0+
Metal supports indirect argument buffers (--msl-argument-buffers). In this case, descriptor sets become argument buffers,
and bindings are mapped to [[id(N)]] within the argument buffer. One quirk is that arrays of resources consume multiple ids,
where Vulkan does not. This can be worked around either from shader authoring stage
or remapping bindings as needed to avoid the overlap.
There is also a rich API to declare remapping schemes which is intended to work like
the pipeline layout in Vulkan. See `CompilerMSL::add_msl_resource_binding`. Remapping combined image samplers for example
must be split into two bindings in MSL, so it's possible to declare an id for the texture and sampler binding separately.
##### HLSL - SM 5.1+
In SM 5.1+, descriptor set bindings are interpreted as register spaces directly. In HLSL however, arrays of resources consume
multiple binding slots where Vulkan does not, so there might be overlap if the SPIR-V was not authored with this in mind.
This can be worked around either from shader authoring stage (don't assign overlapping bindings)
or remap bindings in SPIRV-Cross as needed to avoid the overlap.
#### Linking by name for targets which do not support explicit locations (legacy GLSL/ESSL)
Modern GLSL and HLSL sources (and SPIR-V) relies on explicit layout(location) qualifiers to guide the linking process between shader stages,
but older GLSL relies on symbol names to perform the linking. When emitting shaders with older versions, these layout statements will be removed,
so it is important that the API user ensures that the names of I/O variables are sanitized so that linking will work properly.
The reflection API can rename variables, struct types and struct members to deal with these scenarios using `Compiler::set_name` and friends.
#### Clip-space conventions
SPIRV-Cross can perform some common clip space conversions on gl_Position/SV_Position by enabling `CompilerGLSL::Options.vertex.fixup_clipspace`.
While this can be convenient, it is recommended to modify the projection matrices instead as that can achieve the same result.
For GLSL targets, enabling this will convert a shader which assumes `[0, w]` depth range (Vulkan / D3D / Metal) into `[-w, w]` range.
For MSL and HLSL targets, enabling this will convert a shader in `[-w, w]` depth range (OpenGL) to `[0, w]` depth range.
By default, the CLI will not enable `fixup_clipspace`, but in the API you might want to set an explicit value using `CompilerGLSL::set_options()`.
Y-flipping of gl_Position and similar is also supported.
The use of this is discouraged, because relying on vertex shader Y-flipping tends to get quite messy.
To enable this, set `CompilerGLSL::Options.vertex.flip_vert_y` or `--flip-vert-y` in CLI.
#### Reserved identifiers
When cross-compiling, certain identifiers are considered to be reserved by the implementation.
Code generated by SPIRV-Cross cannot emit these identifiers as they are reserved and used for various internal purposes,
and such variables will typically show up as `_RESERVED_IDENTIFIER_FIXUP_`
or some similar name to make it more obvious that an identifier has been renamed.
Reflection output will follow the exact name specified in the SPIR-V module. It might not be a valid identifier in the C sense,
as it may contain non-alphanumeric/non-underscore characters.
Reserved identifiers currently assumed by the implementation are (in pseudo-regex):
- _$digit+, e.g. `_100`, `_2`
- _$digit+_.+, e.g. `_100_tmp`, `_2_foobar`. `_2Bar` is **not** reserved.
- gl_- prefix
- spv- prefix
- SPIRV_Cross prefix. This prefix is generally used for interface variables where app needs to provide data for workaround purposes.
This identifier will not be rewritten, but be aware of potential collisions.
- Double underscores (reserved by all target languages).
Members of structs also have a reserved identifier:
- _m$digit+$END, e.g. `_m20` and `_m40` are reserved, but not `_m40Foobar`.
## Contributing
Contributions to SPIRV-Cross are welcome. See Testing and Licensing sections for details.
### Testing
SPIRV-Cross maintains a test suite of shaders with reference output of how the output looks after going through a roundtrip through
glslangValidator/spirv-as then back through SPIRV-Cross again.
The reference files are stored inside the repository in order to be able to track regressions.
All pull requests should ensure that test output does not change unexpectedly. This can be tested with:
```
./checkout_glslang_spirv_tools.sh # Checks out glslang and SPIRV-Tools at a fixed revision which matches the reference output.
./build_glslang_spirv_tools.sh # Builds glslang and SPIRV-Tools.
./test_shaders.sh # Runs over all changes and makes sure that there are no deltas compared to reference files.
```
`./test_shaders.sh` currently requires a Makefile setup with GCC/Clang to be set up.
However, on Windows, this can be rather inconvenient if a MinGW environment is not set up.
To use a spirv-cross binary you built with CMake (or otherwise), you can pass in an environment variable as such:
```
SPIRV_CROSS_PATH=path/to/custom/spirv-cross ./test_shaders.sh
```
However, when improving SPIRV-Cross there are of course legitimate cases where reference output should change.
In these cases, run:
```
./update_test_shaders.sh # SPIRV_CROSS_PATH also works here.
```
to update the reference files and include these changes as part of the pull request.
Always make sure you are running the correct version of glslangValidator as well as SPIRV-Tools when updating reference files.
See `checkout_glslang_spirv_tools.sh` which revisions are currently expected. The revisions change regularly.
In short, the main branch should always be able to run `./test_shaders.py shaders` and friends without failure.
SPIRV-Cross uses Travis CI to test all pull requests, so it is not strictly needed to perform testing yourself if you have problems running it locally.
A pull request which does not pass testing on Travis will not be accepted however.
When adding support for new features to SPIRV-Cross, a new shader and reference file should be added which covers usage of the new shader features in question.
Travis CI runs the test suite with the CMake, by running `ctest`. This is a more straight-forward alternative to `./test_shaders.sh`.
### Licensing
Contributors of new files should add a copyright header at the top of every new source code file with their copyright
along with the Apache 2.0 licensing stub.
### Formatting
SPIRV-Cross uses `clang-format` to automatically format code.
Please use `clang-format` with the style sheet found in `.clang-format` to automatically format code before submitting a pull request.
To make things easy, the `format_all.sh` script can be used to format all
source files in the library. In this directory, run the following from the
command line:
./format_all.sh
## Regression testing
In shaders/ a collection of shaders are maintained for purposes of regression testing.
The current reference output is contained in reference/.
`./test_shaders.py shaders` can be run to perform regression testing.
See `./test_shaders.py --help` for more.
### Metal backend
To test the roundtrip path GLSL -> SPIR-V -> MSL, `--msl` can be added, e.g. `./test_shaders.py --msl shaders-msl`.
### HLSL backend
To test the roundtrip path GLSL -> SPIR-V -> HLSL, `--hlsl` can be added, e.g. `./test_shaders.py --hlsl shaders-hlsl`.
### Updating regression tests
When legitimate changes are found, use `--update` flag to update regression files.
Otherwise, `./test_shaders.py` will fail with error code.
### Mali Offline Compiler cycle counts
To obtain a CSV of static shader cycle counts before and after going through spirv-cross, add
`--malisc` flag to `./test_shaders`. This requires the Mali Offline Compiler to be installed in PATH.
