- Subject: Update shared library support on m68k-linux
I've committed some updates for the shared library support on m68k-linux.
Andreas.
2004-11-21 Andreas Schwab <schwab@suse.de>
* m68klinux-tdep.c: Include "glibc-tdep.h" and "solib-svr4.h".
(m68k_linux_init_abi): Set solib_svr4_fetch_link_map_offsets to
svr4_ilp32_fetch_link_map_offsets and gdbarch_skip_solib_resolver
to glibc_skip_solib_resolver.
* config/m68k/linux.mt (TDEPFILES): Add glibc-tdep.o. Remove
solib-legacy.o.
* Makefile.in (m68klinux-tdep.o): Update dependencies.
