- Subject: RFA: update name of glibc PLT fixup function
No regressions on FC6 IA-32. But there are also no reports that this
is necessary. Andreas Schwab simply pointed out that ld-linux.so
doesn't use 'fixup' any more, so I thought I'd be pro-active.
Okay to commit?
gdb/ChangeLog:

* glibc-tdep.c (glibc_skip_solib_resolver): Look for '_dl_fixup',
then plain 'fixup'.
