Bug ID: 20703
Summary: [gas][x86] Cannot assemble certain registers for
vpmuludq instruction
Product: binutils
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: nholcomb at wisc dot edu
Target Milestone: ---
The following instruction produced by objdump cannot be assembled by GAS due to
an error:
Bytes: 62 c1 95 00 f4 41 42
Instruction: vpmuludq 0x420(%r9), %xmm29, %xmm16
ERROR: invalid register operand for `vpmuludq'
This might be a limitation on the part of gas. Checking other decoders like XED
and LLVM, the instruction appears to be valid.
