           Summary: [X86] Assembler does not ensure gather/scatter
                    registers are unique
           Product: libraries
           Version: trunk
          Hardware: PC

            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org

The gather/scatter instructions require certain registers to be unique. The
assembler does not enforce this.

For example, this should not assemble

vgatherdps %xmm2, (%rdi,%xmm2,2), %xmm2
