For recent GLSL versions, if texture2D function call appears, the error
message reports an unsupported type constructor. Change message to
unsupported function. Likewise for other removed texture* function calls.
Specifically, make GLSL link error messages more specific and output
only information relevant to the error.
Also change type printing to more closely reflect GLSL syntax. This
is the default for link error messages, but must me enabled with the
new option --enhanced-msgs for compilation error messages.
Also with --enhanced-msgs, only emit one error message per source
line.
`glslangValidator` will only return [the codes 0..6](b481744aea/StandAlone/StandAlone.cpp (L117-L125)). Fail the test if anything else is returned (like due to the exe crashing).
Also set `LD_LIBRARY_PATH` to contain the `lib` directory before calling glslang.
* Add Shared/Std140 SSBO process & top-level array elements related
process
1.Add process options for shared/std140 ssbo, following ubo process
2.Add IO Variables reflection option, would keep all input/output
variables in reflection
3.Add Top-level related process, fix top-level array size issues,
following spec
4.Split ssbo/ubo reflection options, merge blowup expanding all into
function blowupActiveAggregate to allow other functions keep same entry
format.
Add options in StandAlone and test symbols.
1. Add options in StandAlone for std140/shared ubo/ssbo and all io variables reflection.
2. Add test for ssbo. When EShReflectionSharedStd140SSBO turns on, generated symbol and output would be different, to remind the difference. Defaultly disabled and nothing would change, nor blocking normal test.
* Add options in runtest script, refresh test results.
Add options in StandAlone:
--reflect-all-io-variables --reflect-shared-std140-ubo --reflect-shared-std140-ssbo
refresh test results.
Now the index, size of unsized array are expected.
This CL allows setting the location of glslangValidator and spirv-remap
when calling the runtests script. A test target is added to CMake to
execute runtests and sets the location to the build folder for the two
applications.
Saved about 21K, size down to 380K of MSVC x86 code.
Fixed one bug that needs to be looked at on the master branch:
The test for needing a Vulkan binding has a bug in it, "!layoutAttachment"
which does not mean "no layoutAttachment", because that is non-zero.
This is why some test and test results changed.
Save about 100K.
N.B.: This is done by eliminating a function call, at a high level,
not by #ifdef'ing a bunch of code.
Also, removed no longer needed *_EXTENSION #ifdef in the code not
needed by GLSLANG_WEB.
* This comes from the resolution of issues 4, 5 & 6 in
ARB_program_interface_query, stating that uniform buffers should have their
members expanded out as normal and arrays should have elements added.
* If a buffer block has a large array e.g. [10000] we don't want to iterate over
every array element. Instead we should only expand out the first [0] element,
then expand as normal from there.
* The array name should still be appended with [0] to indicate that it's an
array.
Adds command line options:
--invert-y
--iy
(synonyms) which invert position.Y on vertex shader output. Handles these cases:
* Direct single variable return
* Member of direct returned struct
* Single variable output parameter
* Member of struct output parameter
API:
// Enables position.Y output negation in vertex shader
void TShader::setInvertY(bool invert);
Fixes#1173
Per feedback on PR #1111, this reverses the order of the parameters for the setShiftBinding API.
It is now:
void TShader::setShiftBindingForSet(TResourceType res, unsigned int base, unsigned int set);
This PR adds the ability to provide per-descriptor-set IO mapping shift
values. If a particular binding does not land into a per-set value,
then it falls back to the prior behavior (global shifts per resource class).
Because there were already 6 copies of many different methods and internal
variables and functions, and this PR would have added 6 more, a new API is
introduced to cut down on replication and present a cleaner interface.
For the global (non-set-specific) API, the old entry points still exist
for backward compatibility, but are phrased internally in terms of the
following.
// Resource type for IO resolver
enum TResourceType {
EResSampler,
EResTexture,
EResImage,
EResUbo,
EResSsbo,
EResUav,
EResCount
};
Methods on TShader:
void setShiftBinding(TResourceType res, unsigned int base);
void setShiftBindingForSet(TResourceType res, unsigned int set, unsigned int base);
The first method replaces the 6 prior entry points of various spellings, which
exist now in depreciated form. The second provides per-resource-set functionality.
Both accept an enum from the list above.
From the command line, the existing options can accept either a single shift value as
before, or a series of 1 or more [set offset] pairs. Both can be provided, as in:
... --stb 20 --stb 2 25 3 30 ...
which will use the offset 20 for anything except descriptor set 2 (which uses 25) and
3 (which uses 30).
Also added known-good mechanism to fetch latest validated spirv-tools.
Also added -Od and -Os to disable optimizer and optimize for size.
Fetching spirv-tools is optional for both glsl and hlsl. Legalization
of hlsl is done by default if spirv-opt is present at cmake time.
Optimization for glsl is currently done through the option -Os.
Legalization testing is currently only done on four existing shaders.
A separate baseLegalResults directory holds those results. All previous
testing is done with the optimizer disabled.
Remapper errors are generally fatal: there has been some unexpected situation while
parsing the SPV binary, and there is no reasonable way to carry on. The
errorHandler() function is called in this case, which by default exits, but
it is possible to submit a handler which does not. In that case the remapper would
carry on in a bad state.
This change ensures a graceful termination of the remap() function.
While a try {} catch {} construct would be the ideal and safe way to do this,
that's off limits for certain environments, so this tries to do the same thing
with explicit code, to catch all the bailout paths.
