From comment about this:
Adjust alignment for HLSL rules
TODO: make this consistent in early phases of code: adjusting this late means inconsistencies with earlier code, which for reflection is an issue.
Until reflection is brought in sync with these adjustments, don't apply to $Global,
which is the most likely to rely on reflection, and least likely to rely
implicit layouts.
This was redundant in two ways:
1) it replicated algorithms owned in the front end, and
2) it sometimes left location information on both a block and its members.
OpSpecConstantOp contains an embedded opcode which is given as a literal
argument to the OpSpecConstantOp. The subsequent arguments are as the
embedded op would expect, which may be a mixture of IDs and literals. This
adds support for that to the remapper binary parser. Upon seeing such an
embedded op, the parser flips over to parsing the argument list as
appropriate for that opcode.
Fixes#882.
The codebase seems to use both “#pragma once“ approach, and “#ifndef / #define” approach,
so I picked pragma once as that one is less typing & less brittle.
When glslang is built with some other build system and lumped/unity builds are used,
without the include guards some headers would get included multiple times, leading to duplicate
declaration errors.
This adds infrastructure suitable for any front end to create SPIR-V loop
control flags. The only current front end doing so is HLSL.
[unroll] turns into spv::LoopControlUnrollMask
[loop] turns into spv::LoopControlDontUnrollMask
no specification means spv::LoopControlMaskNone
This reverts commit cfc69d95af.
* Change CMAKE_INSTALL_PREFIX default on Windows in order
to prevent permission denied errors when trying to install
to "Program Files".
* Use `GNUInstallDirs` in order to respect GNU conventions.
This is especially important for multi-arch/multi-lib setups.
* Specify position independent mode building properly, without
using the historic hack of adding `-fPIC` as a definition.
This makes the build system more portable.
* Only detect C++ (and not C) to slightly speed up configuring.
* Specify C++11 mode using modern CMake idioms.
* Fix some whitespace issues.
The SPIR-V generator had assumed tessellation modes such as
primitive type and vertex order would only appear in tess eval
(domain) shaders. SPIR-V allows either, and HLSL allows and
possibly requires them to be in the hull shader.
This change:
1. Passes them through for either tessellation stage, and,
2. Does not set up defaults in the domain stage for HLSl compilation,
to avoid conflicting definitions.
