Default to `-fvisibility=hidden`, and annotate the public glslang interface with `GLSLANG_EXPORT` to change the visibility of these cherry-picked symbols to default.
This is also used by Windows builds for `__declspec(dllexport)`-ing the public DLL interface.
This allows us to classify API changes into those that are publicly backwards compatible, and those that are not.
Note that `libSPIRV` will likely need similar treatment.
Issues: #2283, #1484
Fix#2298.
The AST has two precisions, an operation precision and a result precision.
Actual use of GLSL with mediump samplers wants the result precision, so
pick that up instead of the operation precision.
Now that the HLSL source files are part of the `glslang` target (#2271), it makes sense for these to sit in the `glslang` directory.
Changed the case of the directory from `hlsl` to `HLSL` to better match the sibling directories.
... and stub the HLSL target.
Fixes the building of shared libraries.
This breaks the cyclic dependency between the `glslang` and `hlsl` targets (by essentially removing the `hlsl` target).
The `BUILD.gn` and `BUILD.bazel` build rules already pull the `HLSL` source into the `glslang` target.
`Android.mk` is the only remaining build config that has a dedicated `HLSL` target, but this is explicity static and does not suffer the same link-time issues with the cyclic dependency (we may wish to stub this target too).

* Fix xfb_stride limit issue
Unsized array can't apply to transform trace. layout qualifier "offset" require GL_ARB_enhanced_layouts enable or glsl core version > 440.

Fix compile information issue and test comment issue.

* Fix xfb_stride limit issue
Unsized array can't apply to transform trace. layout qualifier "offset" require GL_ARB_enhanced_layouts enable or glsl core version > 440.
Add negative test for xfb limit
* Move es profile check out of version number check
* Adjust error information and related cases
remove the new version check, refine original version check.
* Revert condition for vulkan, and remove redundant test code.
* 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.
According to the spec glsl4.60.7:
4.4.5. Uniform and Shader Storage Block Layout Qualifiers:
"The packed qualifier overrides only std140, std430, and shared; other qualifiers are inherited.
When packed is used, no shareable layout is guaranteed. The compiler and linker can optimize
memory use based on what variables actively get used and on other criteria. Offsets must be
queried, as there is no other way of guaranteeing where (and which) variables reside within the
block"
we should reserve std140 block and shared block in reflection.
According to the spec glsl4.60.7:
4.4.5. Uniform and Shader Storage Block Layout Qualifiers:
"The row_major and column_major qualifiers only affect the layout of matrices, including all
matrices contained in structures and arrays they are applied to, to all depths of nesting. These
qualifiers can be applied to other types, but will have no effect."
We need ensure all matrix block member been effect.
Support EShMsgKeepUncalled in reflection
EShMsgKeepUncalled is a link message for link program.
We need only one option to control uncalled function optimization.
If we set EShMsgKeepUncalled as false in link time, linker won't be keep the uncall function sequence in AST, and if we set EShMsgKeepUncalled as true in link time, linker will keep all uncalled function sequence in AST.
So, in reflecte time, we just only travers all function sequence. It make EShMsgKeepUncalled only work at linker, and can effect reflection.
Recursively layout packing to "block member"
layout packing isn't set recursively, it causes TReflection::getOffsets doesn't work correctly.
This allows casting from and to any unsigned value, previously this was
undefined behavior.
This fixes ubsan complaining in `TParseContext::layoutQualifierCheck`,
where `~EShLangComputeMask` is used.
* Introduces builtin variables gl_SecondaryFragColorEXT and gl_SecondaryFragDataEXT
* Introduces builtin constant gl_MaxDualSourceDrawBuffersEXT
