Bug ID: 44912
Summary: [AMDGPU][MC][GFX908] dot opcodes operating 4-bit and
8-bit packed data should not support op_sel
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
dot opcodes that have packed data smaller than 16 bits should not allow
op_sel/op_sel_hi modifiers. This is confirmed by Justin Smith.
Examples of failed tests:
v_dot4_u32_u8 v0, v1, v2, v3 op_sel:[1,1]
v_dot8_i32_i4 v0, v1, v2, v3 op_sel_hi:[1,1]
