Description Evandro 2008-03-06 23:31:21 UTC 
If .exitm is used outside a macro definition, then it behaves as .end, stopping
further processing.

For example:

.macro MAC
xor %eax, %eax
.endm

.exitm

MAC

bogus %eax, %eax # never flagged as illegal insn

.end

Hi Evandro,

  Thank you very much for reporting this bug and providing a patch to fix it.

  I have checked your patch in, along with the changelog entry below.  I also
added a testcase to the gas testsuite in order to make sure that this problem
does not reoccur.

Cheers
  Nick
