I tried the patch with a biarch powerpc64-linux compiler; sixtrack now
works with "-m32 -O2 -ftree-loop-linear" but the swim compile dies in a
new place:
/home/janis/tools/gcc-mline-20050323-20612/bin/gfortran -c -o swim.o
-m32 -O2 -ftree-loop-linear swim.f
swim.f: In function ?MAIN__?:
swim.f:46: internal compiler error: in get_loop_body, at cfgloop.c:819
This ought to be reproducible with a vanilla powerpc-linux cross compiler
but I haven't tried that and won't have time to play with this for a few
days.
