2017-10-04[XRay][compiler-rt] Use a hand-written circular buffer in BufferQueueDean Michael Berris
Summary: This change removes the dependency on using a std::deque<...> for the storage of the buffers in the buffer queue. We instead implement a fixed-size circular buffer that's resilient to exhaustion, and preserves the semantics of the BufferQueue. We're moving away from using std::deque<...> for two reasons: - We want to remove dependencies on the STL for data structures. - We want the data structure we use to not require re-allocation in the normal course of operation. The internal implementation of the buffer queue uses heap-allocated arrays that are initialized once when the BufferQueue is created, and re-uses slots in the buffer array as buffers are returned in order. We also change the lock used in the implementation to a spinlock instead of a blocking mutex. We reason that since the release operations now take very little time in the critical section, that a spinlock would be appropriate. This change is related to D38073. This change is a re-submit with the following changes: - Keeping track of the live buffers with a counter independent of the pointers keeping track of the extents of the circular buffer. - Additional documentation of what the data members are meant to represent.

Notably: - `config.android` is dealt with in the common code - `config.compile_wrapper` can be prepended to allow for the use of the android commands - `SCUDO_OPTIONS` must be passed with the environment when running a test - `preinit.cpp` fails with some API levels, not sure why, I will have to dig into this later.

Summary: Mark Android as supported in the cmake configuration for Scudo. Scudo is not added yet in the Android build bots, but code builds and tests pass locally. It is for a later CL. I also checked that Scudo builds as part of the Android toolchain. A few modifications had to be made: - Android defaults to `abort_on_error=1`, which doesn't work well with the current tests. So change the default way to pass `SCUDO_OPTIONS` to the tests to account for this, setting it to 0 by default; - Disable the `valloc.cpp` & `random_shuffle.cpp` tests on Android; - There is a bit of gymnatic to be done with the `SCUDO_TEST_TARGET_ARCH` string, due to android using the `-android` suffix, and `i686` instead of `i386`; - Android doesn't need `-lrt`.

2017-09-18[XRay][compiler-rt] Handle tail-call exits in the XRay runtimeDean Michael Berris
Summary: This change starts differentiating tail exits from normal exits. We also increase the version number of the "naive" log to version 2, which will be the starting version where these records start appearing. In FDR mode we treat the tail exits as normal exits, and are thus subject to the same treatment with regard to record unwriting. Updating the version number is important to signal older builds of the llvm-xray tool that do not deal with the tail exit records must fail early (and that users should only use the llvm-xray tool built after the support for tail exits to get accurate handling of these records).
