I compiled the actual snapshot 20041205 with gcc from last week using ../gcc40/configure --prefix=/usr/local/gcc40c --program-suffix=40c --with- arch=opteron --enable-languages=c,c++ --enable-checking
and CFLAGS="-pipe -g -O3 -march=opteron -fmessage-length=0 -falign-loops=16 -falign-jumps=16 -falign-functions=32 -fstrict-aliasing -fsched-interblock -ffast-math -funroll-all-loops -funit-at-a-time -fpeel-loops -ftracer -funswitch-loops -loop-optimize2 -fmove-loop-invariants -fgcse-after-reload -frename-registers -modulo-sched --param max-gcse-passes=5 --param max-unrolled-insns=600 --param inline-unit-growth=300 --param large-function-growth=400" I got an segfault on my opteron system and an ICE on a ppc system. On both system I did a full boostrap using CFLAGS="-pipe -g -O2 -march=opteron -fmessage-length=0" CFLAGS_FOR_BUILD=<full options> On both system this bootstrap completed. I installed the compiler, cleared the object dir and did a configure / make with CFLAGS=<full options>. On both systems I got ICEs as shown below.
