I'd like to ping patch in
While testing trunk and 4.3 branch for ColdFire, I noticed several
failures in gcc.c-torture testsuite, which the above patch fixes.
The patch was tested on m68k-linux-gnu and m68k-elf (both for coldfire)
with no new regressions.
Without this patch current trunk ICEs in reload when compiling
gcc.c-torture/execute/20060420-1.c for m68k/ColdFire. The fix is safe
(as it just reduces optimization space) and it does not affect
benchmarks (EEMBC and CSiBE were tested).
Is there any chance of committing this before 4.4 branches or should I
ping again when stage1 has started.
