Bug ID: 41156
Summary: [AMDGPU][MC][GFX9] Invalid handling of "-" before
expressions
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: AMDGPU
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Constant expressions started with "-" followed by a symbol are evaluated
incorrectly when used with VOP opcodes. In these cases the "-" sign is simply
ignored.
For example, the sequence
.set foo, 1
v_mul_f32 v0, -foo+2, v2 // -foo+2 = 1?
results in the same code as the following:
v_mul_f32 v0, 3, v2
