The normal IEEE not equal operation tests whether operands are unordered
or not equal (so comparison with a NaN returns true). This corresponds
to the SPIR-V OpFUnordNotEqual, so change to using that.
Analogous to gcc, -g0 would strip all debug info. This is done
regardless of whether optimizations are enabled.

If a uniform has an initializer it will now be given as the optional
initializer operand to the OpVariable instruction.

* HLSL: Fix handling of uniforms in entry point parameters
* HLSL: fix handling of "uniform in"
* Tests: Update baseResults of hlsl.function.frag.out for #2254
* HLSL: fix uniforms in function parameters for opaque types
Swizzled out operands were added in bbbd9a2a. This was sufficient
for most tests, but we ran into problems with umulExtended and
imulExtended, which have two.
This CL converts the tracking values to vectors so multiple operands
can be supported.
Test: KHR-GLES31.core.shader_bitfield_operation.*
Test: ctest
For GLSL function imageAtomicStore, it will be translated to
OpImageTexelPointer + OpAtomicStore. The result type of
OpImageTexelPointer must be the same as the sampled type of OpTypeImage.
On translation, the result type is mistakenly fetched from operand list
operands[2] while operands[2] corresponds to sampleNum whose type is
always uint. This leads to an error if the image type is iimageXXX that is
int image.
Root cause:
GlslangToSpv use symbol structure's ptr as a map key, but multiple shader object can build a new AST.
In the AST the the same symbol has different ptr point to their structure, so indext map faild.
solution:
Add a new map glslangTypeToIdMap to map ptr to symbol id, and use symbol id to index memberRemapper.
v2: Move addCapability and addExtension extension calls from
TGlslangToSpvTraverser::createBinaryOperation to
TGlslangToSpvTraverser::visitAggregate. Suggested by JohnK.
More aggressively prune unreachable code as follows.
When no control flow edges reach a merge block or continue target:
- delete their contents so that:
- a merge block becomes OpLabel, then OpUnreachable
- a continue target becomes OpLabel, then an OpBranch back to the
loop header
- any basic block which is dominated by such a merge block or continue
target is removed as well.
- decorations targeting the removed instructions are removed.
Enables the SPIR-V builder post-processing step the GLSLANG_WEB case.
If the semantics that require the KHR form over the EXT form are seen
(OpBitcast between a vector and a pointer) promote the requested extension
from the EXT to the KHR.
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.
