SPIRVReader has contained a bug for a long time, fixed in KhronosGroup/SPIRV-LLVM-Translator#3373 While the proper fix will be backported to earlier branches - it still will take a lot of time for adoption by LTS driver. Hence we have to add a W/A restoring old behaviour of lifetime intrinsics translation, inserting artificial bitcast to i8*. PR also includes update of a test from KhronosGroup/SPIRV-LLVM-Translator#3376 Signed-off-by: Sidorov, Dmitry <[email protected]>

There was a problem hiding this comment.
This strip bitcast is missing in intel/llvm, but it present in every other repository, both Khronos and downstream.
