Bug ID: 41298
Summary: [AMDGPU][MC] Incorrect parsing of NAME:VALUE modifiers
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]
When VALUE is specified as a constant expression which starts with a "-"
followed by a number, the negation operation is applied to the whole expression
rather than to the first number.
An example:
// GFX9
global_load_dword v1, v[3:4], off offset:-1+1
Assembling this instruction results in the same code as the following:
// GFX9
global_load_dword v1, v[3:4], off offset:-2
A similar bug 41156 manifests itself in another context.
