Thiago Jung Bauermann <bauerman@br.ibm.com> Tom Tromey <tromey@redhat.com> * breakpoint.c (condition_command): Simplify. Move condition setting code to ... (set_breakpoint_condition): ... here. New function. * breakpoint.h (set_breakpoint_condition): Declare. * Makefile.in (SUBDIR_PYTHON_OBS): Add py-breakpoint. (SUBDIR_PYTHON_SRCS): Likewise. (py-breakpoint.o): New rule. * python/py-breakpoint.c: New file. * python/python-internal.h (gdbpy_breakpoints) (gdbpy_initialize_breakpoints): Declare. (GDB_PY_SET_HANDLE_EXCEPTION) Define. 2010-04-09 Phil Muldoon <pmuldoon@redhat.com> * gdb.python/py-breakpoint.exp: New File. * gdb.python/py-breakpoint.C: Ditto. 2010-04-09 Phil Muldoon <pmuldoon@redhat.com> Thiago Jung Bauermann <bauerman@br.ibm.com> Tom Tromey <tromey@redhat.com> * gdb.texinfo (Breakpoints In Python): New Node.
