I was wondering if anyone has built GCC using a CFLAGS (and CXXFLAGS) setting that causes GCC to generate code that is not compatibile with the default GCC output. Basically, I am building GCC on ia64-hp-hpux11.31 where I set CFLAGS and CXXFLAGS to "-mlp64" to generate 64 bit code instead of the default 32 bit code. During the build libiberty is built in 64 bit mode but then the object files that go into genmodes (genmodes.o, errors.o, etc) are compiled without using CFLAGS and the link of genmodes fails because genmodes.o and errors.o are in 32 bit mode and libiberty is in 64 bit mode.
I have tried setting CFLAGS_FOR_BUILD and ALL_CFLAGS but these didn't have any affect. Is there a flag that I am missing or is this a bug in the build process? This problem only seems to occur when I am doing a bootstrap build, if I use --disable-bootstrap and build all-gcc then I don't have this problem. Steve Ellcey s...@cup.hp.com
