Bug ID: 35962
Summary: [AMDGPU][MC] Incorrect encoding of VDATA for image
atomics
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: AMDGPU
Assignee: unassignedb...@nondot.org
Reporter: dpreobrazhen...@luxoft.com
CC: llvm-bugs@lists.llvm.org
VDATA specified in the instruction is not encoded; VADDR is encoded instead.
For example (VI):
image_atomic_add v6, v255, s[8:15] dmask:0x1
0x00,0x01,0x48,0xf0,0xff,0xff,0x02,0x00 // VADDR=VDATA=0xff
image_atomic_add v252, v2, s[8:15] dmask:0x1
0x00,0x01,0x48,0xf0,0x02,0x02,0x02,0x00 // VADDR=VDATA=0x02
