gdb/ * infcmd.c (finish_backward): Set a step-resume breakpoint at the function's entry point instead of a manually managed momentary breakpoint, and only ever issue one proceed call. * infrun.c (handle_inferior_event) <BPSTAT_WHAT_STEP_RESUME>: If doing a reverse-finish, switch to stepi mode, to do another step. (insert_step_resume_breakpoint_at_sal): Make public. (normal_stop): No need to save function value return registers if going reverse. * inferior.h (insert_step_resume_breakpoint_at_sal): Declare. gdb/testsuite/ * gdb.reverse/finish-reverse-bkpt.exp: New test.
