From 1557b85d755f3373e232f6c3acb643b1e2992eec Mon Sep 17 00:00:00 2001 From: Andrew Cagney Date: Mon, 17 Mar 2003 14:23:50 +0000 Subject: 2003-03-17 Andrew Cagney Fix frame off-by-one bug. * frame-unwind.h (frame_this_id_ftype): Replace frame_unwind_id_ftype. (frame_prev_register_ftype): Replace frame_unwind_reg_ftype. (struct frame_unwind): Replace "id" with "this_id". Replace "reg" with "prev_register". * frame-unwind.c (frame_unwind_find_by_pc): Return legacy_saved_regs_unwind instead of trad_frame_unwind. Update comment. * dummy-frame.c (cached_find_dummy_frame): Delete function. (dummy_frame_this_id): Replace dummy_frame_id_unwind. (dummy_frame_prev_register): Replace dummy_frame_register_unwind. (dummy_frame_unwind): Update. * sentinel-frame.c (sentinel_frame_prev_register): Replace sentinel_frame_register_unwind. (sentinel_frame_this_id): Replace sentinel_frame_id_unwind. (sentinel_frame_unwinder): Update. * frame.h (legacy_saved_regs_unwind): Replace trad_frame_unwind. (struct frame_info): Rename "unwind_cache" to "prologue_cache". * frame.c (create_sentinel_frame): Update. Initialize "prologue_cache" instead of "unwind_cache". (frame_register_unwind): Call this frame's prev_register with the next frame and this frame's prologue cache. (get_prev_frame): Simplify. Always call prev frame's this_id with this frame and prev frame's prologue cache. Document that this call is shifted one to the left when compared to the frame_register_unwind call. (legacy_saved_regs_prev_register): Replace frame_saved_regs_register_unwind. (legacy_saved_regs_this_id): Replace frame_saved_regs_id_unwind. (legacy_saved_regs_unwinder): Replace trad_frame_unwinder. (legacy_saved_regs_unwind): Replace trad_frame_unwind. * d10v-tdep.c (d10v_frame_this_id): Replace d10v_frame_id_unwind. (d10v_frame_unwind): Update. (d10v_frame_prev_register): Replace d10v_frame_register_unwind. (d10v_frame_unwind_cache): Replace this "fi" with "next_frame". (saved_regs_unwinder): Replace this "frame" with "next_frame", and "saved_regs" with "this_saved_regs". --- gdb/frame-unwind.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) (limited to 'gdb/frame-unwind.c') diff --git a/gdb/frame-unwind.c b/gdb/frame-unwind.c index a889f955d84..c72d24a0b23 100644 --- a/gdb/frame-unwind.c +++ b/gdb/frame-unwind.c @@ -83,16 +83,19 @@ frame_unwind_find_by_pc (struct gdbarch *gdbarch, CORE_ADDR pc) int i; struct frame_unwind_table *table = gdbarch_data (gdbarch, frame_unwind_data); - /* Seriously old code.
