Revert "Vulkan:Include precision qualifier in GLSL" This reverts commit 93e72f5f0eb80b89334ea8fe577b32901a00b5fb. Reason for revert: This is having a negative impact on gfxbench Manhattan 3.1 tests (20-30%) with only a minor improvement (~4%) in TRex offscreen. Pulling out for now and need to re-evaluate best solution here. Original change's description: > Vulkan:Include precision qualifier in GLSL > > With this initial implementation, it's possible to get precision > qualifier mis-matches in the generated GLSL 4.50. According to the > spec this is allowed. From GLSLangSpec 4.50 section 4.7 "Precision and > Precision Qualifiers": > > For the purposes of determining if an output from one shader stage > matches an input of the next stage, the precision qualifier need not > match. > > However, when converted to SPIR-V and run through the shader validation > any mismatches will cause shader validation errors. Initially just > ignoring those errors with this commit. > > Bug: angleproject:3078 > Change-Id: Ia2b04f90f0a7b6b1302c1b1b3e32bcfd8db9ed49 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2057749 > Reviewed-by: Jamie Madill <jmadill@chromium.org> > Reviewed-by: Tobin Ehlis <tobine@google.com> > Reviewed-by: Tim Van Patten <timvp@google.com> > Commit-Queue: Tobin Ehlis <tobine@google.com> TBR=tobine@google.com,timvp@google.com,jmadill@chromium.org # Not skipping CQ checks because original CL landed > 1 day ago.
