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.
Testing just with arm.exp is not enough.
Ok if no regressions running the entire regression testsuite for C and
C++ for arm*-*-*eabi with an iwmmxt configuration.
Thanks
