config.gcc (*-*-openbsd*): Add fragment to compile libgcc correctly for shared configurations.
2001-07-13 Marc Espie <espie@cvs.openbsd.org>
* config.gcc (*-*-openbsd*): Add fragment to compile libgcc
correctly for shared configurations.
* config/t-libgcc-pic: New.
* config/{i386,m68k,sparc}/t-openbsd: New.
* config/openbsd.h: Include cpu_spec in cpp_spec where needed.
Support -shared. Support debugging libraries with -g.
* config/i386/openbsd.h: Correct ASM_COMMENT_START. Ensure dwarf2
frame information does not emit pointer diffs.
* config/sparc/openbsd.h: Ensure dwarf2 frame information does not
emit pointer diffs.
