[PATCH] D149579: [X86][MC] Fix parsing Intel syntax indirect branch with symbol only

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

It looks we accept a case (`t2`, w/o or with the patch) that GNU as rejects.

  % as -msyntax=intel =(printf 'call qword ptr [rip + fn_ref]') -o gcc.o
  /tmp/zshjfuv2e: Assembler messages:
  /tmp/zshjfuv2e: Warning: end of file not at end of a line; newline inserted
  /tmp/zshjfuv2e:1: Error: invalid operands (*UND* and *UND* sections) for `+'

We parse it as `callq   *fn_ref(%rip)`.
