            Bug ID: 31388
           Summary: There is no document for -moperand-check
           Product: binutils
           Version: 2.43 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com

commit 7bab8ab56f7c09acbaca2645314e0622b20c2afe
Author: Jan Beulich <jbeulich@novell.com>
Date:   Tue Aug 7 16:55:00 2012 +0000

    The VGATHER group of instructions requires that all three involved
    xmm/ymm registers are distinct. This patch adds code to check for this,
    and at once eliminates a superfluous check for not using PC-relative
    addressing for these instructions (the fact that an index register is
    required here already excludes valid PC-relative addresses). The
    severity of the resulting diagnostics can be controlled via command
    line option or directive.

added the assembler option, -moperand-check.  But there is no documentation
for this option.
