Summary: Merge r324353 into the 6.0 branch
Product: libraries
Version: 6.0
Hardware: PC
OS: Linux
Status: NEW
Severity: release blocker
Priority: P
Component: Backend: AMDGPU
Assignee: unassignedb...@nondot.org
Reporter: b...@basnieuwenhuizen.nl
CC: llvm-bugs@lists.llvm.org
Blocks: 35804
r324353 fixes a GPU hang due to to a pseudo instruction generated with a new
pattern not having SGPR->VGPR promotion support.
"AMDGPU: Fix S_BUFFER_LOAD_DWORD_SGPR moveToVALU.
It moves the offset to vgpr, but did not handle being called for
any of the other arguments, while LLVM 5 would select
BUFFER_LOAD_DWORD_OFFEN immediately, which does the right thing.
This calls legalizeOperands to fix up the operands after we converted
to a BUFFER_LOAD_DWORD_OFFEN."
