Personal I would prefer to get it byte for byte identical. I can mention that it seems to be an arm-elf issue, we build powerpc-eabi(spe) and bfin-elf the same way and they don't produce output that differs, any hints about that? We've also tried Cygwin built toolchains, they produce the same output as the mingw hosted. Seems to bee an Linux VS Windows issue. Regards Andreas Btw, the solution wasn't implemented in the gcc-4.2.2 and the ChangeLog didn't mention why or why not. tree-ssa-live.c ... static int compare_pairs (const void *p1, const void *p2) { #if 0 partition_pair_p * pp1 = (partition_pair_p *) p1; partition_pair_p * pp2 = (partition_pair_p *) p2; int result; result = (* pp2)->cost - (* pp1)->cost; /* Issue 128204: Cygwin vs Linux host differences: If the costs are the same, use the partition indicies in order to obtain a stable, reproducible sort.
