From 516034834f1bcade05e3dcd85e9c7c8b899adbd6 Mon Sep 17 00:00:00 2001 From: Daniel Jacobowitz Date: Sun, 5 Jan 2003 01:39:56 +0000 Subject: * arm-tdep.c (arm_frame_chain_valid): Remove unnecessary test. * d10v-tdep.c (d10v_frame_chain_valid): Remove unnecessary tests. * hppa-tdep.c (hppa_frame_chain_valid): Remove unnecessary test. * blockframe.c: Include "gdbcmd.h" and "command.h". (backtrace_below_main): New variable. (file_frame_chain_valid, func_frame_chain_valid) (nonnull_frame_chain_valid, generic_file_frame_chain_valid) (generic_func_frame_chain_valid): Remove functions. (frame_chain_valid, do_flush_frames_sfunc): New functions. (_initialize_blockframe): New function. * Makefile.in (blockframe.o): Update dependencies. * frame.c (frame_saved_regs_id_unwind, get_prev_frame): Remove FIXME comment. Call frame_chain_valid (). * frame.h: Remove old prototypes. Add prototype for frame_chain_valid and update comments to match. * gdbarch.sh: Change FRAME_CHAIN_VALID into a predicated function. Remove old comment. * gdbarch.h: Regenerated. * gdbarch.c: Regenerated. Plus updates to all other targets not to provide a FRAME_CHAIN_VALID. --- gdb/config/m68k/tm-apollo68b.h | 4 +--- gdb/config/m68k/tm-m68kv4.h | 6 +----- gdb/config/m68k/tm-monitor.h | 7 +------ gdb/config/m68k/tm-os68k.h | 10 +--------- gdb/config/m68k/tm-vx68.h | 11 ++--------- 5 files changed, 6 insertions(+), 32 deletions(-) (limited to 'gdb/config/m68k') diff --git a/gdb/config/m68k/tm-apollo68b.h b/gdb/config/m68k/tm-apollo68b.h index d43eec9..f0b7488 100644 --- a/gdb/config/m68k/tm-apollo68b.h +++ b/gdb/config/m68k/tm-apollo68b.h @@ -1,5 +1,5 @@ /* Parameters for execution on Apollo 68k running BSD. - Copyright 1986, 1987, 1989, 1991, 1993, 1994, 1998 + Copyright 1986, 1987, 1989, 1991, 1993, 1994, 1998, 2003 Free Software Foundation, Inc.
