reduced test case in C
Depends on target CPU selection. -mcpu=680[012346]0 and -mcpu=cpu32 all work,
but -mcpu=5206 (or apparently any other coldfire) ICEs.
Indeed. Fixed by not trying to use negqi2 directly, but going
through the normal expanders which will DTRT for coldfire.
Tested via cross-compile, committed to mainline and 4.7.
This patch indeed helps me over the ICE from PR 52481, but now I am
tripping over the next bootstrap breakdown (gcc-4_7-branch,
--target=m68k-rtems4.11):
