Matt Arsenault	ce16b6835b	AMDGPU: Don't kill super-register with overlapping copy ... This would end up killing part of the result super-register, resulting in a verifier error on a later use of the overlapping registers. We could add kills of any non-aliasing registers, but we should be moving away from relying on kill flags.	2020-10-16 09:34:35 -04:00
Matt Arsenault	e56e9022bc	AMDGPU: Fix liveness errors when copying AGPR tuples ... Avoid recursively calling copyPhysReg for AGPR handling. This was dropping the necessary super register implicit defs to avoid liveness verifier errors.	2020-07-30 18:13:04 -04:00

Pushpinder Singh	e1a31f52cd	[AMDGPU] Control num waves per EU for implicit work-group size ... Summary: If amdgpu-flat-work-group-size is not specified in LLVM IR, the backend uses default value of 1024. For this, minimum waves per EU should be 4. However, backend is still setting minimum value to 1 instead of calculated value. This is not observed normally as frontend always provide amdgpu-flat-work-group-size attribute.

Matt Arsenault	a230f1db3f	AMDGPU: Fix missing tracksRegLiveness in tests ... I have no idea why this is considered optional, or why it's not the default. Also add uses of the copied registers for more useful liveness testing.	2020-07-01 18:58:59 -04:00
