Subject: [patch 1/2] Fix linking on non-x86* after libgdb.a removal
Hi,
I am sorry but I found after the patch
[patch 2/2] Do not build libgdb.a by default
http://sourceware.org/ml/gdb-patches/2011-12/msg00716.html
For example s390x-linux-gnu no longer builds native GDB:
corelow.o:(.bss+0x0): multiple definition of `core_gdbarch'
corelow.o:(.bss+0x0): first defined here
corelow.o: In function `deprecated_add_core_fns':
corelow.c:(.text+0x0): multiple definition of `deprecated_add_core_fns'
corelow.o:corelow.c:(.text+0x0): first defined here
I have found more such duplicates:
solib.o is clear, that one is now in COMMON_OBS. BTW it seems this change
broke functionality of xcoffsolib.c due to:
powerpc-*-aix* | rs6000-*-*)
gdb_host=aix ;;
as xcoffsolib.c probably cannot work with solib.c together but that is offtopic
here, I do not have access+interest in AIX.
xcoffread.o is also clear, powerpc/aix.mh NATDEPFILES get used only together
with configure.tgt entry for the same target which is:
powerpc-*-aix* | rs6000-*-*)
# Target: PowerPC running AIX
gdb_target_obs="rs6000-tdep.o rs6000-aix-tdep.o xcoffread.o \
ppc-sysv-tdep.o solib-svr4.o"
There remains that more complicated corelow.o for the next patch.
gdbtui was bigger performance hit than libgdb.a but after libgdb.a got removed
I do not want to revert that patch as this duplicity fix does not look hard.
Sorry,
Jan
