# 687ec75d	22-Oct-2018	Matt Arsenault <[email protected]>	DAG: Change behavior of fminnum/fmaxnum nodes Introduce new versions that follow the IEEE semantics to help with legalization that may need quieted inputs. There are some regressions from inserting DAG: Change behavior of fminnum/fmaxnum nodes Introduce new versions that follow the IEEE semantics to help with legalization that may need quieted inputs. There are some regressions from inserting unnecessary canonicalizes when these are matched from fast math fcmp + select which should be fixed in a future commit. llvm-svn: 344914 show more ...

Handle any type of load since in principle we should do the same combine for the various load intrinsics. llvm-svn: 341219 show more ...

# 1349a04e	22-May-2018	Matt Arsenault <[email protected]>	AMDGPU: Make v2i16/v2f16 legal on VI This usually results in better code. Fixes using inline asm with short2, and also fixes having a different ABI for function parameters between VI and gfx9. Part AMDGPU: Make v2i16/v2f16 legal on VI This usually results in better code. Fixes using inline asm with short2, and also fixes having a different ABI for function parameters between VI and gfx9. Partially cleans up the mess used for lowering of the d16 operations. Making v4f16 legal will help clean this up more, but this requires additional work. llvm-svn: 332953 show more ...
