The original mail had also the second part:

# 2009-10-25  Jan Kratochvil  <jan.kratochvil@redhat.com>
# 
# gdb/testsuite/
#         * gdb.base/unload.c (main): Change the UNLOADSHR parameter to 1.
#         Replace the printf call of Y by provided "y-set-1" label.  New block
#         for the second shared library.
#         * gdb.base/unload.exp: Compile also the second library, call
#         gdb_load_shlibs also for it.  Use now gdb_breakpoint.
#         (single pending breakpoint info): Rename to ...
#         (pending breakpoint info before run): ... this extended test.
#         (libfile2, libname2, libsrcfile2, libsrc2)
#         (lib_sl2): New variables.
#         (exec_opts): Set also SHLIB_NAME2.
#         (pending breakpoint info on first run at shrfunc1)
#         (pending breakpoint info on second run at shrfunc1)
#         (pending breakpoint info on second run at shrfunc2)
#         (print y from libfile, print y from libfile2): New tests.
#         * gdb.base/unloadshr.c (shrfunc1): Change the returned value.
#         * gdb.base/unloadshr2.c: New.

Do I understand it correctly your approval is for the gdb/ part while the
gdb/testsuite/ part is still left pending for review some other day?


Thanks for the review,
Jan
