- Reverted public function interface changes for C++.
- Added override member variable to TShader.
- Added accessor TShader::setOverrideVersion.
- Reverted changes to tests.
This change list allows a user to override the GLSL version from the
command line or through the C and C++ interfaces. This will override the
override happens in ProcessDeferred() before DeduceVersionProfile() so
the process should still error out if the version is insufficient for
the shader code.
- Added --glsl-version <version> to CLI.
- Added parameter to route glslVersion as override version to
preprocessor and parse functions to C++ interface.
- Updated C interface with function to override GLSL version.
Add command line support which enables the following behavior:
- Remap discard
Map discard to DemoteToHelperInvocation for HLSL shaders. Map to
OpTerminateInvocation for GLSL shaders.
- Decorate HelperInvocation with Volatile
- Use localSizeId for execution mode
WorkGroupSize is deprecated in spirv1.6
Also update known goods to SPIRV 1.6
1. The test cases of OpReadClockKHR is invalid. The return type is
unsigned integer rather than signed integer.
2. When SPIR-V decorate or SPIR-V type is specified, we should avoid
auto location mapping because the semantics are totally decided by
SPIR-V tokens.
The signedness of type char is implementation-defined in C++. The
conversion to (signed) int8 currently uses a cast to char, which is
undefined for negative values when the type char is implemented as
unsigned. Thus, fix to cast to "signed char", which has the intended
semantic on all implementations.
Fixes#2807
There were two implementations of isInf() and isNan(), in Constant.cpp
and in intermOut.cpp. The former only works on little-endian systems,
the latter is a wrapper for library functions and works regardless of
endianness. Move the second version into Common.h and adopt it in both
places. Thereby avoid the duplication and fix for big-endian systems.
A previous commit with the same intent and purpose had missed a required
header for builds on Windows.
On s390x, this fixes the test case
Glsl/CompileToAstTest.FromFile/constFold_frag.

Otherwise this can race with other threads for access to the fields it's
supposed to be initializing/finalizing.
For example, imagine another thread is calling ShInitialize() while the
first thread is calling ShFinalize() - the finalize function would
destroy the state at the same time as the initialize function is trying
to initialize it.
Holding on to the global lock for the entire function prevents all of
these failure modes.
1. spirv_execution_mode_id and spirv_decorate_id could support
specialization constants. The original implementation always
assume only normal frontend constants are valid. It is not true.
2. spirv_type donesn't support type_specifier as an option of
spirv_type_parameter. At present, only constant_expression is the
valid option.
it's a little strange how the resolver takes an arbitrary intermediate
in it's constructor. Really this should be an 'options' object that
holds the various resolve/remapping options which are read from this
intermediate.
At least for now rename it so it's more clear it's used differently from
other intermediates that are accessed in the resolver (such as the per
stage ones).
* add ability to upgrade uniform block to push constants assuming it fits within the size limit imposed by the caller
* allow selecting the packing for the auto push constants
* check the size using the potential layout packing of the push constants
