Bug ID: 71268
   Summary: [PATCH] Fix description of x86_64's -m32 option
   Product: gcc
   Version: unknown
Status: UNCONFIRMED
  Severity: trivial
  Priority: P3
 Component: other

Patch to fix the description

The -m32 option only instructs GCC to produce 32-bit code, but does
not alter the target processor.

So the original description is wrong in that code generated by using
this option will not run on all i386 processors.

Ping. The issue is still valid. Is the revised patch acceptable? How can I
improve it?

I see, I didn't see your comment before attaching it; I had already come up
with that patch before filing the bug.
