From 516034834f1bcade05e3dcd85e9c7c8b899adbd6 Mon Sep 17 00:00:00 2001 From: Daniel Jacobowitz Date: Sun, 5 Jan 2003 01:39:56 +0000 Subject: [PATCH] * 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/ChangeLog | 57 ++++++++++++++ gdb/Makefile.in | 2 +- gdb/alpha-tdep.c | 1 - gdb/arm-tdep.c | 2 +- gdb/avr-tdep.c | 3 +- gdb/blockframe.c | 133 +++++++++++++++++++------------- gdb/config/m32r/tm-m32r.h | 2 - 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 +-- gdb/config/mn10200/tm-mn10200.h | 3 +- gdb/config/sparc/tm-sparclite.h | 5 +- gdb/cris-tdep.c | 3 +- gdb/d10v-tdep.c | 11 +-- gdb/frame.c | 22 +----- gdb/frame.h | 17 +--- gdb/frv-tdep.c | 1 - gdb/gdbarch.c | 19 ++++- gdb/gdbarch.h | 28 +++++-- gdb/gdbarch.sh | 9 +-- gdb/h8300-tdep.c | 1 - gdb/hppa-tdep.c | 3 - gdb/i386-tdep.c | 7 -- gdb/ia64-tdep.c | 3 +- gdb/m68hc11-tdep.c | 4 +- gdb/m68k-tdep.c | 4 +- gdb/mcore-tdep.c | 3 +- gdb/mips-tdep.c | 1 - gdb/mn10300-tdep.c | 4 +- gdb/ns32k-tdep.c | 1 - gdb/ppcnbsd-tdep.c | 3 - gdb/rs6000-tdep.c | 2 - gdb/s390-tdep.c | 1 - gdb/sh-tdep.c | 1 - gdb/sparc-tdep.c | 8 -- gdb/v850-tdep.c | 1 - gdb/vax-tdep.c | 1 - gdb/x86-64-tdep.c | 5 +- 40 files changed, 203 insertions(+), 206 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 63fbb552e7a..774ac880ead 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,60 @@ +2003-01-04 Daniel Jacobowitz + + * 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.
