Works faster than gcc and the warning messages are interesting ;-> In the last couple of weeks, since wide-int code went into gcc trunk, this has broke. clang suggested using flag -fheinous-gnu-extensions, but that didn't help. Here is 20140514 failing to bootstrap Comparing stages 2 and 3 warning: gcc/cc1-checksum.o differs warning: gcc/cc1plus-checksum.o differs Bootstrap comparison failure! gcc/simplify-rtx.o differs gcc/fold-const.o differs gcc/tree-ssa-ccp.o differs make[2]: *** [compare] Error 1 make[2]: Leaving directory `/home/dcb/gcc/working' make[1]: *** [stage3-bubble] Error 2 make[1]: Leaving directory `/home/dcb/gcc/working' make: *** [bootstrap] Error 2 Thu 15 May 18:28:51 BST 2014 Configure line is ../src/trunk/configure --prefix=/home/dcb/gcc/results --enable-checking=release --enable-languages=c,c++,fortran --disable-werror CC="clang -g -O2 -Wall -fheinous-gnu-extensions" CXX="clang++ -g -O2 -Wall -fheinous-gnu-extensions" and bootstrap line is make BOOT_CFLAGS='-g -O3' CFLAGS_FOR_TARGET='-g -O3' -j 2 bootstrap
