Issue ID: 16857
Summary: inline assembler reverses operands of VPEXTRW
instruction
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
The following code:
void foo() {
asm {
vpextrw EBX, XMM2, 0xF;
}
}
Compiles to:
C5 F9 C5 DA 0F vpextrw EDX,XMM3,0Fh
But the 'modregrm' DA should be D3, i.e. the 'reg' and 'rm' fields are swapped.
This reversal doesn't happen with the vpextrb instruction.
