[PATCH, ARM, iWMMXT] PR target/54338 - Include IWMMXT_GR_REGS in ALL_REGS

Tue, 02 Apr 2013 02:45:35 -0700 

Hi,
  According to Vladimir Makarov's analysis, the root cause of PR target/54338 
is that ALL_REGS doesn't contain IWMMXT_GR_REGS in REG_CLASS_CONTENTS.
  It seems there is no reason to exclude the IWMMXT_GR_REGS from ALL_REGS as 
IWMMXT_GR_REGS are the real registers.
  This patch simply makes ALL_REGS include IWMMXT_GR_REGS to fix this PR.
  Since the test case gcc.target/arm/mmx-2.c would fail for the same reason and 
become pass with this fix, no extra test case need to be add.
  Pass arm.exp test. Patch attached.

ChangeLog

        * config/arm/arm.h (REG_CLASS_CONTENTS): Include IWMMXT_GR_REGS in 
ALL_REGS.


OK?

Thanks,
Xinyu
