OK, seems like there were unused TARGET_MACHO macros that would protect
these errors from happening. I made some modifications that add #if
TARGET_MACHO.
Now the error is a linkage problem:
/home/varth/project/llvm-cvs/llvm-gcc4/obj/gcc/xgcc: symbol lookup
error: /home/varth/project/llvm-cvs/llvm-gcc4/obj/gcc/libgcc_s.so.1:
undefined symbol: __thenan_sf
And even if I force the definition of thenan_sf with
const fp_number_type __thenan_sf = { CLASS_SNAN, 0, 0, {(fractype) 0} };
I still get the error.
Cheers,
Nicolas

I assume this is supposed to be coming from gcc/config/fp-bit.c, but I don't know how any of this stuff works. -Chris> Cheers, > Nicolas > > Nicolas Geoffray wrote: >> Chris Lattner wrote: >> >>> This looks like you're compiling llvm-gcc3, which is quite dead by now. >>> Please follow these instructions: >>> http://llvm.org/docs/CFEBuildInstrs.html >>> >>> >>> >> Oups, sorry for that.
