A patch for gcc/Makefile.in
- To: egcs at cygnus dot com
- Subject: A patch for gcc/Makefile.in
- From: hjl at lucon dot org (H.J. Lu)
- Date: Fri, 17 Oct 1997 16:24:47 -0700 (PDT)
With this patch, I can use -fno-exceptions to compile gcc while
still getting a working libgcc.a.
I also added -fno-exceptions to crtbeginS.o crtendS.o.

* Makefile (GCC_BASE_CFLAGS): New.
(GCC_CFLAGS): Changed to $(GCC_BASE_CFLAGS) $(CFLAGS).
(LIBGCC2_EXTRA_CFLAGS): New, set to $(CFLAGS).
(LIBGCC2_CFLAGS): Use $(LIBGCC2_EXTRA_CFLAGS) $(GCC_BASE_CFLAGS)
instead of $(GCC_CFLAGS).
(crtbeginS.o crtendS.o): Add -fno-exceptions.
