Bug ID: 36332
Summary: R9285 Unreal tournament game hang since [AMDGPU]
Suppress redundant waitcnt instrs.
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: AMDGPU
Assignee: unassignedb...@nondot.org
Reporter: adf.li...@gmail.com
CC: llvm-bugs@lists.llvm.org
R9285 since below the Uneral Tournament alpha after some random time will hang
in its display thread and after a timeout enter its error reporting and quit
with a segfault (haven't found the details for that).
There is nothing in dmesg and it seems no harm is done to GPU/System.
