For the last few days I've been unable to make or bootstrap on i386-apple-darwin8.10.1. It doesn't seem to be a problem on my Core2-based Mac Pro, but on my Intel Core Duo (MacBook Pro) the build fails with the error message below.
Perhaps we're trying to use Core2-only instructions on this platform? Is there a workaround? - Doug /Users/dgregor/Projects/mainlinegcc-build/./gcc/xgcc -B/Users/dgregor/Projects/mainlinegcc-build/./gcc/ -B/Users/dgregor/Projects/mainlinegcc-install/i386-apple-darwin8.10.1/bin/ -B/Users/dgregor/Projects/mainlinegcc-install/i386-apple-darwin8.10.1/lib/ -isystem /Users/dgregor/Projects/mainlinegcc-install/i386-apple-darwin8.10.1/include -isystem /Users/dgregor/Projects/mainlinegcc-install/i386-apple-darwin8.10.1/sys-include -g -fkeep-inline-functions -O2 -O2 -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -pipe -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. -I../.././gcc -I../../../mainlinegcc/libgcc -I../../../mainlinegcc/libgcc/. -I../../../mainlinegcc/libgcc/../gcc -I../../../mainlinegcc/libgcc/../include -DHAVE_CC_TLS -o unwind-dw2_s.o -MT unwind-dw2_s.o -MD -MP -MF unwind-dw2_s.dep -DSHARED -fexceptions -c ../../../mainlinegcc/libgcc/../gcc/unwind-dw2.c :3825:operands given don't match any known 386 instruction :5178:operands given don't match any known 386 instruction :5198:operands given don't match any known 386 instruction :6196:operands given don't match any known 386 instruction :7709:operands given don't match any known 386 instruction :7835:operands given don't match any known 386 instruction :8030:operands given don't match any known 386 instruction :8126:operands given don't match any known 386 instruction :8310:operands given don't match any known 386 instruction :8390:operands given don't match any known 386 instruction :8491:operands given don't match any known 386 instruction make[3]: *** [unwind-dw2_s.o] Error 1 make[2]: *** [all-stage1-target-libgcc] Error 2 make[1]: *** [stage1-bubble] Error 2 make: *** [all] Error 2
