Currently, when creating a gdb.FinishBreakpoint in a function called from an inline frame, it will never be hit: ``` (gdb) py fb=gdb.FinishBreakpoint() Temporary breakpoint 1 at 0x13f1917b4: file C:/src/repos/binutils-gdb.git/gdb/testsuite/gdb.python/py-finish-breakpoint.c, line 47. (gdb) c Continuing. Thread-specific breakpoint 1 deleted - thread 1 no longer in the thread list. [Inferior 1 (process 1208) exited normally] ``` The reason is that the frame_id of a breakpoint has to be the ID of a real frame, ignoring any inline frames. With this fixed, it's working correctly: ``` (gdb) py fb=gdb.FinishBreakpoint() Temporary breakpoint 1 at 0x13f5617b4: file C:/src/repos/binutils-gdb.git/gdb/testsuite/gdb.python/py-finish-breakpoint.c, line 47. (gdb) c Continuing. Breakpoint 1, increase_inlined (a=0x40fa5c) at C:/src/repos/binutils-gdb.git/gdb/testsuite/gdb.python/py-finish-breakpoint.c:47 (gdb) py print(fb.return_value) -8 ``` Approved-By: Tom Tromey <tom@tromey.com>
