From 7df05f2b91d56bb6305625b73f0180187f4d66ff Mon Sep 17 00:00:00 2001 From: Andrew Cagney Date: Sat, 5 Apr 2003 03:56:00 +0000 Subject: 2003-04-04 Andrew Cagney * frame.c (get_prev_frame): Do not call frame_type_from_pc. Set the frame's type from the unwinder. (get_frame_type): Map UNKNOWN_FRAME onto NORMAL_FRAME. (create_new_frame, legacy_get_prev_frame): When the unwinder's type isn't UNKNOWN_FRAME, initalize "type" from the unwinder. (get_frame_base_address): Use get_frame_type. (get_frame_locals_address, get_frame_args_address): Ditto. (legacy_saved_regs_unwinder): Set the type to UNKNOWN_TYPE. * frame.h (enum frame_type): Add UNKNOWN_FRAME. (struct frame_info): Add comment explaining why the frame contains a "type" field. * dummy-frame.c (dummy_frame_unwind): Set the type to DUMMY_FRAME. * d10v-tdep.c (d10v_frame_unwind): Set the type to NORMAL_FRAME. * sentinel-frame.c (sentinel_frame_unwinder): Set the type to NORMAL_FRAME. * frame-unwind.h: Include "frame.h". (struct frame_unwind): Add "type" field. * Makefile.in (frame_unwind_h): Add $(frame_h). --- gdb/frame.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'gdb/frame.h') diff --git a/gdb/frame.h b/gdb/frame.h index 231aaad..9870fc2 100644 --- a/gdb/frame.h +++ b/gdb/frame.h @@ -225,6 +225,11 @@ extern int frame_relative_level (struct frame_info *fi); enum frame_type { + /* The frame's type hasn't yet been defined.
