Far thunking breaks GCC build #41

Closed mfld-fr closed 5 years ago

I tried to build your latest commit (bfd61dc), and I got an error:

GCC is built that way (from ELKS tools/Makefile):

cd gcc-build && ../gcc-src/configure --target=ia16-elf --prefix="$(CROSSDIR)" --without-headers --enable-languages=c --disable-libssp --without-isl
make -C gcc-build

I guess the root cause is not linked to #40, so I opened a distinct issue for this one.

Hello @mfld-fr ,

Thanks for the report. I guess I did not notice that <sys/types.h> was tied to a C runtime library, and that libgcc.a should only need whatever facilities are available from the compiler itself.

(I had been trying to add some support for calling near functions (in the default text segment) from other text segments, using some sort of thunking (this will make the far_section function attribute a lot more useful than it is now). I have reverted the problematic commit --- since it seems I will need to redo the implementation in any case.)

Thank you!

Just tested with commit 2aa70f8c292e4e67b980d7468a011206130bfd7d: build completes now without any error. Thank you for the quick fix !
