This adds a minimalistic implementation of getcontext() for Android/ARM and Android/x86. The provided code is in assembly and only implements the bare minimum required by Breakpad to get the current processor state. Note that: - The FPU state is not saved to the ucontext_t on ARM. (that's actually the main difference with a normal getcontext() implementation). This is normal. On Linux/ARM, such state must be obtained with PTRACE_GETVFPREGS instead. This will be implemented in a future patch. - On x86, only the 'regular' FPU state is saved, to mimic the GLibc/i386 implementation. The state of SSE/SSE2/etc registers is not part of the upstream getcontext() implementation.

# ndk-build module definition for the Google Breakpad client library

|
#
|
|
# To use this file, do the following:
|
|
#
|
|
# 1/ Include this file from your own Android.mk, either directly
|
|
# or with through the NDK's import-module function.
|
|
#
|
|
# 2/ Use the client static library in your project with:
|
|
#
|
|
# LOCAL_STATIC_LIBRARIES += breakpad_client
|
|
#
|
|
# 3/ In your source code, include "src/client/linux/exception_handler.h"
|
|
# and use the Linux instructions to use it.
|
|
#
|
|
# This module works with either the STLport or GNU libstdc++, but you need
|
|
# to select one in your Application.mk
|
|
#
|
|
|
|
# Sanity check. We can only build for ARM for now.
