Did so. I copied the reload.o files that were created by: make restage2 BOOT_CFLAGS="-O2 -g -fomit-frame-pointer" and: make restage3 BOOT_CFLAGS="-O2 -g -fomit-frame-pointer" into: GCC/FSF/bootstrap-failure_gcc-4.0-20041212/stage2 and: GCC/FSF/bootstrap-failure_gcc-4.0-20041212/stage3 and then did the following with them: otool -tV GCC/FSF/bootstrap-failure_gcc-4.0-20041212/stage3/reload.o &> stage3.reload.o.otool.s otool -tV GCC/FSF/bootstrap-failure_gcc-4.0-20041212/stage2/reload.o &> stage2.reload.o.otool.s which yielded two nice assembler files that I'll attach here (plus a diff for quick overview) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18972
