Hi,
due to recent discussion on the basic asm, and the special handling of
ASM_INPUT in ia64, I tried to build a bare-metal cross-compiler for ia64, but
that did not work, because it seems to be impossible to build it without having
a stdlib.h.
With the attached patch, I was finally able to build the cross compiler, by
declaring abort in the way as it is done already in many other places at libgcc.
In case someone wants to know, working configure options are as follows:
../binutils-2.25.1/configure --prefix=../ia64-elf --target=ia64-unknown-elf
../gcc-trunk/configure --prefix=../ia64-elf --target=ia64-unknown-elf
--enable-languages=c --with-gnu-as --disable-threads --disable-sjlj-exceptions
--disable-libssp --disable-libquadmath
I have successfully built a bare-metal cross compiler with this patch.
Is it OK for trunk?
I wouldn't call it "many" places in libgcc. I just see one -- fp-bit.c
and that one is only to give "sane" handle to extended mode floating point.
For ia64-elf ISTM this header should be coming from newlib.
