From 125f8a3ddedd413a2290dae011f0bed9ffc78278 Mon Sep 17 00:00:00 2001 From: Gary Benson Date: Thu, 19 Jun 2014 14:46:38 +0100 Subject: Move shared native target specific code to gdb/nat https://sourceware.org/gdb/wiki/Common describes the following directory structure: gdb/nat/ Native target backend files. Code that interfaces with the host debug API. E.g., ptrace code, Windows debug API code, procfs code should go here. gdb/target/ Host-independent, target vector specific code (target_ops). gdb/common/ All other shared code. This commit moves all native target backend files currently in gdb/common to gdb/nat. gdb/ 2014-06-20 Gary Benson * common/gdb_thread_db.h: Moved to nat. All includes updated. * common/glibc_thread_db.h: Likewise. * common/i386-cpuid.h: Likewise. * common/i386-gcc-cpuid.h: Likewise. * common/linux-btrace.h: Likewise. * common/linux-osdata.h: Likewise. * common/linux-procfs.h: Likewise. * common/linux-ptrace.h: Likewise. * common/mips-linux-watch.h: Likewise. * common/linux-btrace.c: Moved to nat. * common/linux-osdata.c: Likewise. * common/linux-procfs.c: Likewise. * common/linux-ptrace.c: Likewise. * common/mips-linux-watch.c: Likewise. * nat/gdb_thread_db.h: Moved from common. * nat/glibc_thread_db.h: Likewise. * nat/i386-cpuid.h: Likewise. * nat/i386-gcc-cpuid.h: Likewise. * nat/linux-btrace.c: Likewise. * nat/linux-btrace.h: Likewise. * nat/linux-osdata.c: Likewise. * nat/linux-osdata.h: Likewise. * nat/linux-procfs.c: Likewise. * nat/linux-procfs.h: Likewise. * nat/linux-ptrace.c: Likewise. * nat/linux-ptrace.h: Likewise. * nat/mips-linux-watch.c: Likewise. * nat/mips-linux-watch.h: Likewise. * Makefile.in (HFILES_NO_SRCDIR): Reflect new locations. (object file files): Reordered. * gdb/copyright.py (EXCLUDE_LIST): Reflect new location of glibc_thread_db.h. gdb/gdbserver/ 2014-06-20 Gary Benson * Makefile.in (SFILES): Update locations for files moved from common to nat. (object file files): Reordered. gdb/testsuite/ 2014-06-20 Gary Benson * gdb.arch/i386-avx.exp: Fix include file location. * gdb.arch/i386-sse.exp: Likewise. --- gdb/common/linux-procfs.c | 121 ---------------------------------------------- 1 file changed, 121 deletions(-) delete mode 100644 gdb/common/linux-procfs.c (limited to 'gdb/common/linux-procfs.c') diff --git a/gdb/common/linux-procfs.c b/gdb/common/linux-procfs.c deleted file mode 100644 index 1443a88..0000000 --- a/gdb/common/linux-procfs.c +++ /dev/null @@ -1,121 +0,0 @@ -/* Linux-specific PROCFS manipulation routines. - Copyright (C) 2009-2014 Free Software Foundation, Inc. - - This file is part of GDB. - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
