From 7d85a9c0e3639345cb6d19c139ccb9da5095fc76 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Tue, 17 Mar 2009 19:28:09 +0000 Subject: [PATCH] Add a target_ops parameter to the to_kill method in struct target_ops. * target.h (struct target_ops): Add a "target_ops *" parameter to method to_kill. (target_kill): Remove macro. Add declaration. * target.c (debug_to_kill): Delete, no longer necessary. (target_kill): New function. (update_current_target): Stop inheriting the to_kill method. Do not de_fault it to no_process either. (setup_target_debug): Do not set current_target.to_kill. * gnu-nat.c, go32-nat.c, hpux-thread.c, inf-ptrace.c, inf-ttrace.c, linux-nat.c, monitor.c, nto-procfs.c, procfs.c, remote-m32r-sdi.c, remote-mips.c, remote-sim.c, remote.c, windows-nat.c: Update accordingly. --- gdb/ChangeLog | 17 +++++++++++++++++ gdb/gnu-nat.c | 2 +- gdb/go32-nat.c | 8 ++++---- gdb/hpux-thread.c | 4 ++-- gdb/inf-ptrace.c | 2 +- gdb/inf-ttrace.c | 2 +- gdb/linux-nat.c | 2 +- gdb/monitor.c | 2 +- gdb/nto-procfs.c | 2 +- gdb/procfs.c | 4 ++-- gdb/remote-m32r-sdi.c | 2 +- gdb/remote-mips.c | 3 +-- gdb/remote-sim.c | 6 +++--- gdb/remote.c | 6 +++--- gdb/target.c | 34 +++++++++++++++++++--------------- gdb/target.h | 5 ++--- gdb/windows-nat.c | 6 +++--- 17 files changed, 63 insertions(+), 44 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index ce50ba2eb3a..1759b0b0046 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,20 @@ +2009-03-17 Joel Brobecker + + Add a target_ops parameter to the to_kill method in struct target_ops. + + * target.h (struct target_ops): Add a "target_ops *" parameter to + method to_kill. + (target_kill): Remove macro.
