Explicitly Add Aliased Memory Decoration in SpirV In GLSL, aliased memory qualifier is implicitly available, unless we explicitly specify the memory is restrict: https://www.khronos.org/opengl/wiki/Type_Qualifier_(GLSL)#Memory_qualifiers. However, in SpirV, aliased memory qualifier has to be explicitly specified: https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#AliasingSection This change adds the aliased memory decorations to SSBO if the GLSL does not specify the restrict memory qualifier. This is a temporary workaround to fix the deqp test failures on some android devices. Eventually we would like to waive this test for ANGLE due to alised memory in Vulkan does not suppose to affect SSBOs that have different set/binding, please refer to this Khronos ticket for more details: https://gitlab.khronos.org/Tracker/vk-gl-cts/-/issues/4321 Bug: b/266235549 Change-Id: Ic7afc417a5d421664b60e0413a011314787e14e7 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4312130 Reviewed-by: Yiwei Zhang <zzyiwei@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org>
