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.
Also use this to move deferred member-function-body parsing to a better
place.
This should also be well poised for implementing the 'namespace' keyword.
Added version check (version >= 150) for GL_(core/compatibility)_profile macros.
Added GL_core_profile standard macro check to "150.vert" test file.
Fixed version check for GL_core_profile macros, and removed bad token character from 150.vert test.
Updated 150.vert.out test base-result with google-test suite.
This is slightly cleaner today for entry-point wrapping, which sometimes made
two subtrees for a function definition instead of just one subtree. It will be
critical though for recognizing a struct with multiple member functions.
Use an explicit cast from size_t to int to avoid errors like the following:
glslang\glslang\MachineIndependent\preprocessor\Pp.cpp(1053) : error C2220: warning treated as error - no 'object' file generated
glslang\glslang\MachineIndependent\preprocessor\Pp.cpp(1053) : warning C4267: '=' : conversion from 'size_t' to 'int', possible loss of data
affects Pp.cpp, hlslParseHelper.cpp.
Initialize local variable to get rid of warningsa about potentially
uninitialized variables:
glslang\hlsl\hlslparsehelper.cpp(3667) : error C2220: warning treated as error - no 'object' file generated
glslang\hlsl\hlslparsehelper.cpp(3667) : warning C4701: potentially uninitialized local variable 'builtIn' used
affects hlslParseHelper.cpp
This PR adds the ability to pass structuredbuffer types by reference
as function parameters.
It also changes the representation of structuredbuffers from anonymous
blocks with named members, to named blocks with pseudonymous members.
That should not be an externally visible change.
New command line option --shift-ssbo-binding mirrors --shift-ubo-binding, etc.
New reflection query getLocalSize(int dim) queries local size, e.g, CS threads.
This obsoletes WIP PR #704, which was built on the pre entry point wrapping master. New version
here uses entry point wrapping.
This is a limited implementation of tessellation shaders. In particular, the following are not functional,
and will be added as separate stages to reduce the size of each PR.
* patchconstantfunctions accepting per-control-point input values, such as
const OutputPatch <hs_out_t, 3> cpv are not implemented.
* patchconstantfunctions whose signature requires an aggregate input type such as
a structure containing builtin variables. Code to synthesize such calls is not
yet present.
These restrictions will be relaxed as soon as possible. Simple cases can compile now: see for example
Test/hulsl.hull.1.tesc - e.g, writing to inner and outer tessellation factors.
PCF invocation is synthesized as an entry point epilogue protected behind a barrier and a test on
invocation ID == 0. If there is an existing invocation ID variable it will be used, otherwise one is
added to the linkage. The PCF and the shader EP interfaces are unioned and builtins appearing in
the PCF but not the EP are also added to the linkage and synthesized as shader inputs.
Parameter matching to (eventually arbitrary) PCF signatures is by builtin variable type. Any user
variables in the PCF signature will result in an error. Overloaded PCF functions will also result in
an error.
[domain()], [partitioning()], [outputtopology()], [outputcontrolpoints()], and [patchconstantfunction()]
attributes to the shader entry point are in place, with the exception of the Pow2 partitioning mode.
This needs some render testing, but is destined to be part of master.
This also leads to a variety of other simplifications.
- IO are global symbols, so only need one list of linkage nodes (deferred)
- no longer need parse-context-wide 'inEntryPoint' state, entry-point is localized
- several parts of splitting/flattening are now localized
