Glad to see GCC has so good internals documentation. I've fixed it to use
TARGET_{OS,CPU}_CPP_BUILTINS, hacked some other config stuff and got c,c++
to pass "make check" with just a few errors.
I'm not sure how to define the __i386__ macro portably though. I'm forced to
add this define unconditionaly in kfreebsdgnu.h:
#undef TARGET_CPU_CPP_BUILTINS
#define TARGET_CPU_CPP_BUILTINS() \
builtin_define ("__i386__"); \
builtin_define_std ("i386"); \
builtin_assert ("cpu=i386"); \
builtin_assert ("machine=i386");
Otherwise stage1 breaks because of xgcc not defining __i386__. Other systems
don't hardcode cpu macros in their headers; What is the correct way to get
these macros defined?
Thanks,
