            Bug ID: 26115
           Summary: x86 xsuspldtrk mnemonic should be xsusldtrk
           Product: binutils
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: bnutls at mail dot com
  Target Milestone: ---

x86/x64:

Intel uses `xsusldtrk` but gas uses `xsuspldtrk` (note the extra `p`). I don't
see a good reason to not use the official mnemonic.

Intel docs:

binutils source:

opcodes/i386-opc.tbl:

// TSXLDTRK instructions.

xsuspldtrk, 0, 0xf20f01e8, None, 3, CpuTSXLDTRK,
No_bSuf|No_wSuf|No_lSuf|No_sSuf|No_qSuf|No_ldSuf, { 0 }
xresldtrk, 0, 0xf20f01e9, None, 3, CpuTSXLDTRK,
No_bSuf|No_wSuf|No_lSuf|No_sSuf|No_qSuf|No_ldSuf, { 0 }

// TSXLDTRK instructions end.
