This option increases the max_id_bound in the optimizer to 0x3FFFFFFF, and then runs a
compact-id pass if the final result has a max_id greater than the standard limit of 0x3FFFFF.
Also eliminates dead output variables and unused output variable
components. Finally calls aggressive dead code elimination.
AnalyzeDeadOutputStores also supplied to be called on the following
shader to provide input for the Eliminate* function.
It can't be safely used unilaterally on other stages, since that will
result in output/input mismatches between stages. They arn't
having their output variables eliminated accordingly.
Also update known goods to Vulkan 1.3 support
Also re-enable SPIR-V 1.6 tests with vulkan1.3 target
Also re-cache SPIRV 1.6 header which somehow regressed back to 1.5
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
Generate load of interpolant for first operand to GLSLstd450
InterpolateAt* SPIR-V ops. This allows the interpolants to
propagate from the input struct in the wrapper around main
into the shader during HLSL legalization. A new pass has been
added to legalization which will remove the load and replace
with the pointer of the load to create valid external
interpolate op.
Fixes#2584
If GL_EXT_scalar_block_layout is requested by the shader, set the
option to allow scalar blocks in the SPIR-V validator.
Fix the existing tests using scalar layout to not expect "Validation
failed".
Fixes#2400.
* Add new SpirvToolsDisassemble API interface + Improve Doc on existing API interface (#2408)
* Add more flexible SpirvToolsDisassemble interface to allow specifying spv_target_env for disassembly output.
Improve documentation on existing SpirvToolsDisassemble interface.
* Update pre-processor check - following existing ENABLE_OPT checks.
* Fix not-found header paths for glslangValidator and glslangtests.
* Add spirv_tools/include path where there is an ENABLE_OPT=1 in the BUILD.gn configuration.
* Do not use PropagateLineInfoPass and RedundantLineInfoElimPass
Since spirv-opt will remove PropagateLineInfoPass and
RedundantLineInfoElimPass, glslang should not use it. spirv-opt will
propagate the line instructions and eliminate the redundant lines by
default in IR loading/emission.
* Update known_good.json for spirv-tool
Analogous to gcc, -g0 would strip all debug info. This is done
regardless of whether optimizations are enabled.

The spvtools::Optimizer::Run method glslang is using constructs a default set
of spvtools::OptimizerOptions. This default set of options instructs the
validator to run. That is not quite correct since glslang will invoke the
validator _explicitly_ after the optimization pass.
