Bug ID: 33838
Summary: Incorrect operand sizes for MMX instructions
Product: tools
Version: 4.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: llvm-as
Assignee: unassignedb...@nondot.org
Reporter: pe...@trailofbits.com
CC: llvm-bugs@lists.llvm.org
The x86 MMX variants of punpcklbw, punpcklwd, punpckldq that operate on memory
operate on dwords, but the LLVM assembler only accepts qword ptr arguments.
For example, LLVM rejects the following:
punpcklwd mm0, dword ptr [rsp]
and incorrectly accepts the following:
punpcklwd mm0, qword ptr [rsp]
