Message : Vulkan: Call glslang at compile time With this change, the ANGLE translator immediately compiles the generated GLSL into SPIR-V with glslang and discards the source. This is in preparation for generating SPIR-V directly, by making the frontend and backend already able to digest it. This change also allows the expensive glslang calls to be parallelized, improving the following perf test by about 20%: LinkProgramBenchmark.Run/vulkan_compile_and_link_multi_thread Previously, the test was run as such in the Vulkan backend: Main Thread 1 Thread 2 Compile1 ---> Compile2 ---------------------> Translator Translator <--- <--------------------- Link glslang for shader1 glslang for shader2 Done With this change, it is run as such: Main Thread 1 Thread 2 Compile1 ---> Compile2 ---------------------> Translator Translator glslang glslang <--- <--------------------- Link Done glslang_wrapper_utils no longer interacts with glslang! A rename will follow.
