From 62d486be7c8b6e866c3104b6e8170e69db0a95f1 Mon Sep 17 00:00:00 2001 From: "digit@chromium.org" Date: Tue, 21 Aug 2012 14:34:48 +0000 Subject: Improve Android support This patch remove many Android-specific #ifdefs from the Breakpad source code. This is achieved by providing "fixed-up" platform headers (e.g. or ), in the new directory src/common/android/include/, which masks differences between the NDK and GLibc headers. The old "android_link.h" and "android_ucontext.h" are moved and renamed. This also requires putting this directory as the first include path during Android-hosted builds, hence the modification of Makefile.am and configure.ac Review URL: https://breakpad.appspot.com/434002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1017 4c0a9323-5329-0410-9bdc-e9ce6186880e --- src/common/android/include/elf.h | 159 +++++++++++++++++++++++++++++ src/common/android/include/link.h | 67 ++++++++++++ src/common/android/include/stab.h | 100 ++++++++++++++++++ src/common/android/include/sys/procfs.h | 113 +++++++++++++++++++++ src/common/android/include/sys/signal.h | 35 +++++++ src/common/android/include/sys/stat.h | 39 +++++++ src/common/android/include/sys/ucontext.h | 163 ++++++++++++++++++++++++++++++ src/common/android/include/sys/user.h | 134 ++++++++++++++++++++++++ src/common/android/include/ucontext.h | 41 ++++++++ 9 files changed, 851 insertions(+) create mode 100644 src/common/android/include/elf.h create mode 100644 src/common/android/include/link.h create mode 100644 src/common/android/include/stab.h create mode 100644 src/common/android/include/sys/procfs.h create mode 100644 src/common/android/include/sys/signal.h create mode 100644 src/common/android/include/sys/stat.h create mode 100644 src/common/android/include/sys/ucontext.h create mode 100644 src/common/android/include/sys/user.h create mode 100644 src/common/android/include/ucontext.h (limited to 'src/common/android/include') diff --git a/src/common/android/include/elf.h b/src/common/android/include/elf.h new file mode 100644 index 00000000..debe30be --- /dev/null +++ b/src/common/android/include/elf.h @@ -0,0 +1,159 @@ +// Copyright (c) 2012, Google Inc. +// All rights reserved. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are +// met: +// +// * Redistributions of source code must retain the above copyright +// notice, this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above +// copyright notice, this list of conditions and the following disclaimer +// in the documentation and/or other materials provided with the +// distribution. +// * Neither the name of Google Inc. nor the names of its +// contributors may be used to endorse or promote products derived from +// this software without specific prior written permission. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +// A PARTICULAR PURPOSE ARE DISCLAIMED.
