Bug ID: 41361
Summary: [AMDGPU][MC][GFX9] Incorrect parsing of op_sel* and
neg_* modifiers
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
Assembler supports the following syntax variants for these modifiers:
STRING:[X]
STRING:[X,Y]
STRING:[X,Y,Z]
STRING:[X,Y,Z,W]
The 4th variant must end with "]", however assembler accepts any token.
Examples of GFX9 code which trigger no errors:
v_max3_f16 v5, v1, v2, v3 op_sel:[1,1,1,1,
v_max3_f16 v5, v1, v2, v3 op_sel:[1,1,1,1[
v_max3_f16 v5, v1, v2, v3 op_sel:[1,1,1,1 1
