Bug ID: 46421
Summary: [AMDGPU][MC][GFX10] An out-of-range MTBUF 'format'
modifier does not trigger an error
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: AMDGPU
Assignee: unassignedb...@nondot.org
Reporter: dpreobrazhen...@luxoft.com
CC: llvm-bugs@lists.llvm.org
This modifier should specify a 7-bit unsigned value however any 8-bit value is
accepted.
An example of a failed test:
tbuffer_store_format_x v0, v1, s[0:3], format:255, 0 idxen
This code is assembled without errors and results in the same encoding as
produced for the following valid opcode:
tbuffer_store_format_x v0, v1, s[0:3], format:127, 0 idxen
