Nathan Gauër	1a7f71afb4	clean: constexpr-ify and unify anon namespace use (#4991) ... Constexpr guaranteed no runtime init in addition to const semantics. Moving all opt/ to constexpr. Moving all compile-unit statics to anonymous namespaces to uniformize the method used (anonymous namespace vs static has the same behavior here AFAIK).

alan-baker	d35a78db57	Switch SPIRV-Tools to use spirv.hpp11 internally (#4981) ... Fixes #4960 * Switches to using enum classes with an underlying type to avoid undefined behaviour	2022-11-04 17:27:10 -04:00
Jaebaek Seo	d997c83b10	Add spirv-opt pass to replace descriptor accesses based on variable indices (#4574) ... This commit adds a spirv-opt pass to replace accesses to descriptor array based on variable indices with constant elements. Before: ``` %descriptor = OpVariable %_ptr_array_Image Uniform ... %ac = OpAccessChain %_ptr_Image %descriptor %variable_index (some image instructions using %ac) ``` After: ``` %descriptor = OpVariable %_ptr_array_Image Uniform ... OpSwitch %variable_index 0 %case0 1 %case1 ... ... %case0 = OpLabel %ac = OpAccessChain %_ptr_Image %descriptor %uint_0 ... %case1 = OpLabel %ac = OpAccessChain %_ptr_Image %descriptor %uint_1 ... (use OpPhi for value with concrete type) ```	2021-10-26 17:20:58 -04:00
