Matt Arsenault	79ff188add	AMDGPU/GlobalISel: Legalize G_FPOW There are few differences from the DAG handling. First, the DAG handling uses a primitive selection pattern instead of custom legalizing it. Because of this, this makes use of source modifiers while the DAG does not. Also instead of promoting f16, try to use the f16 log/exp. There's no f16 fmul_legacy, so widen just for the multiply, although I'm not sure that's the best solution.	2020-02-21 10:31:13 -05:00

AMDGPU/GlobalISel: Legalize G_FPOW

There are few differences from the DAG handling. First, the DAG
handling uses a primitive selection pattern instead of custom
legalizing it. Because of this, this makes use of source modifiers
while the DAG does not.

Also instead of promoting f16, try to use the f16 log/exp. There's no
f16 fmul_legacy, so widen just for the multiply, although I'm not sure
that's the best solution.
