[PATCH] D89170: [AMDGPU] Use flat scratch instructions where available

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec updated this revision to Diff 300113.
rampitec added a comment.

Fixed issue with flat scratch not always being initialized. It was not initialized if we had no stack objects or calls, but later did spilling.
It is too late to insert system SGPRs at frame lowering, so initialize it always if flat scratch is used.
