Mirko Brkusanin	ae36c02ad0	[AMDGPU] Set DS alignment requirements to be more strict ... Alignment requirements for ds_read/write_b96/b128 for gfx9 and onward are now the same as for other GCN subtargets. This way we can avoid any unintentional use of these instructions on systems that do not support dword alignment and instead require natural alignment. This also makes 'SH_MEM_CONFIG.alignment_mode == STRICT' the default. Differential Revision: https://reviews.llvm.org/D87821	2020-09-18 15:26:24 +02:00
Jay Foad	c799f873cb	[AMDGPU] Don't cluster stores ... Clustering loads has caching benefits, but as far as I know there is no advantage to clustering stores on any AMDGPU subtargets. The disadvantage is that it tends to increase register pressure and restricts scheduling freedom. Differential Revision: https://reviews.llvm.org/D85530	2020-09-14 13:40:17 +01:00
Mirko Brkusanin	0654ff703d	[AMDGPU] Use ds_read/write_b96/b128 when possible for SDag ... Do not break down local loads and stores so ds_read/write_b96/b128 in ISelLowering can be selected on subtargets that support them and if align requirements allow them.
