From c0eca49f4e3382163153a1cdbb090a25b4a32e31 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 16 Jan 2014 11:39:32 -0700 Subject: [PATCH] convert to_decr_pc_after_break This converts to_decr_pc_after_break to the new style of delegation, removing forward_target_decr_pc_after_break. 2014-02-19 Tom Tromey * record-btrace.c (record_btrace_decr_pc_after_break): Delegate directly. * target-delegates.c: Rebuild. * target.h (struct target_ops) : Use TARGET_DEFAULT_FUNC. * target.c (default_target_decr_pc_after_break): Rename from forward_target_decr_pc_after_break. Simplify. (target_decr_pc_after_break): Rely on delegation. --- gdb/ChangeLog | 11 +++++++++++ gdb/record-btrace.c | 2 +- gdb/target-delegates.c | 10 ++++++++++ gdb/target.c | 15 +++++++-------- gdb/target.h | 3 ++- 5 files changed, 31 insertions(+), 10 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index d41f14ed4cd..ff6188b0347 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,14 @@ +2014-02-19 Tom Tromey + + * record-btrace.c (record_btrace_decr_pc_after_break): Delegate + directly. + * target-delegates.c: Rebuild. + * target.h (struct target_ops) : Use + TARGET_DEFAULT_FUNC. + * target.c (default_target_decr_pc_after_break): Rename from + forward_target_decr_pc_after_break.
