            Bug ID: 24253
           Summary: X86 Vcomis uses xmmword ptr (instead of dword ptr)
           Product: binutils
           Version: 2.33 (HEAD)
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: p.antoine at catenacyber dot fr
  Target Milestone: ---

Calling `print_insn_i386` with buffer \xc5\xf8\x2f\x10 returns `vcomiss
xmm2,dword ptr [eax]` when it should return `vcomiss xmm2,xmmword ptr [eax]`
Same goes with \xc5\xf9\x2f\x10 vcomisd xmm2,qword ptr [eax]
