[PATCH] D71358: AMDGPU: Remove denormal subtarget features

[Matt Arsenault via Phabricator via llvm-commits]

arsenm created this revision.
arsenm added a reviewer: rampitec.
Herald added subscribers: hiraditya, t-tye, tpr, dstuttard, yaxunl, nhaehnle, wdng, jvesely, kzhuravl.
Herald added a project: LLVM.

Switch to using the denormal-fp-math/denormal-fp-math-f32
attributes. Determine the defaults from the calling convention, to
assume flushing in graphics shaders by default.
