This avoids regressions in a future AMDGPU change to make v4i16/v4f16 legal. For these types, build_vector is implemented as bitcasted operations on v2i32. This combine was creating v4i16s out of what would have been already been a v2i32 build_vector, creating a mess of nodes that never get cleaned up. I'm not sure this is the right condition to check. I initially tried just checking for the legality of the new build_vector. This works for my case, but breaks dozens of x86 tests. A Mips test seems to show some improvement or at least a neutral change. I don't want to think about how long it would take to analyze the set of different x86 vector operations impacted. Test included in future commit. llvm-svn: 334218 |
