* 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.
* Introduces builtin variables gl_SecondaryFragColorEXT and gl_SecondaryFragDataEXT
* Introduces builtin constant gl_MaxDualSourceDrawBuffersEXT
* enables support for layout qualifier "index" in es profile
* rework how shader interface block naming rules are handled
* Fixes 2136
According to the spec, shader interfaces (uniform blocks, buffer
blocks, input blocks, output blocks) all should be matched up via
their block names across all compilation units, not instance names.
Also, all block names can be re-used between all 4 interface types
without conflict. This change makes it so all of these blocks are
matched and remapped using block name and not by instance name.
Additional the rule that matched uniform and buffer blocks must
either be anonymous or named (but not nessearily the same name) is
now imposed.
* add warning if instance names differ between matched shader interfaces
* Add test cases from #2137 which is now fixed as well.
* replace some tab characters with spaces
* buffer blocks and uniform blocks now share the same block namespace
When we use unsized array in shader storage buffer, glslang calculate the offset during delcaring the block, it may lead to incorrect block offsets when its implicit array size changed.
So here is what we do:
1. For GLSL, we add flag explicitOffset in TQualifier, and set it when layout offset is specified explicitly
2. By using this flag we could tell difference as whether it is an explicit offset, and recalculate the block member offset conditionally in OpenGL.
TPoolAllocator is not copy assignable, so this setter could never have
been used. After a recent change (878a24ee2), new versions of Clang
reject this code outright.
The changes to glslang/glslang/MachineIndependent/ParseHelper.cpp exist
purely to prevent even more instances of "warning: enumeration value
‘EOp...’ not handled in switch"
v2: Remove 8-bit types. Overzealous copy-and-paste led to adding
support for a bunch of types that the extension doesn't actually enable.
v3: Update expected test results file. Just changing an expected
results file to make a test pass seems sketchy to me, but I'm not sure
what else to do.
v4: Add missing entry for EOpAbsDifference in
TOutputTraverser::visitBinary. Noticed by JohnK.
