* Use breakpad_getcontext on all Linux platforms missing getcontextMichael Forney2020-03-161-1/+15
| | | | | | | | | | | | | | | | | | | | getcontext is also not available on musl libc, so generalize breakpad_getcontext so it can be used as a fallback for non-Android platforms as well. On x86_64 and i386, ucontext_t uses an Android-specific offset for storage of FP registers, since its sigset_t differs in size. So, make the definition of MCONTEXT_FPREGS_MEM and UCONTEXT_FPREGS_MEM_OFFSET conditional on whether we are building for Android. On glibc and musl, signal.h and asm/sigcontext.h can't be included together, so in breakpad_context_unittest.cc, only compare the libc and kernel _fpstate when on Android.

* Add support for parsing the DW_AT_ranges attributesGabriele Svelto2018-08-131-5/+5
| | | | | | | | | | | | | | | | This enables the DWARF reader to properly parse DW_AT_ranges attributes in compilation units and functions. Code covered by a function is now represented by a vector of ranges instead of a single contiguous range and DW_AT_ranges entries are used to populate it. All the code and tests that assumed functions to be contiguous entities has been updated to reflect the change. DW_AT_ranges attributes found in compilation units are parsed but no data is generated for them as it is not currently needed.

* Make minidump name generation on Linux as random as possibleGabriele Svelto2017-04-121-4/+84
| | | | | | | | | | | | | | | This patch ensures that two crashes taken within the same second have different minidump names. The random characters used in the minidump filename are now read from /dev/urandom where possible or generated via arc4random(). If neither is available we fall back to regular rand() but mixing the address of an object to the current time when generating the random seed to make it slightly less predictable.

| | | | | | | | | | | | | | | | | The Rust compiler uses GCC C++ name mangling, but it has another layer of encoding so abi::cxa_demangle doesn't produce great results.

* Add custom getcontext() implementation for Android.digit@chromium.org2012-08-311-47/+863
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | This patch remove many Android-specific #ifdefs from the Breakpad source code. This is achieved by providing "fixed-up" platform headers (e.g. <signal.h> or <sys/user,h>), 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.
