      runtime: fix data race in findfunc() · 91f0f181
      Dmitriy Vyukov authored
      The data race can lead to reads of partially
      initialized concurrently mutated symbol data.
      The change also adds a simple sanity test
      for Caller() and FuncForPC().

      syscall: move bsd pipe syscall · eb2b3f5d
      Joel Sing authored
      Not all BSDs have the same pipe() syscall implementation - move the Darwin/FreeBSD specific implementation into their respective OS syscall files. This will be needed to add OpenBSD syscall support.

      runtime: improve Linux mutex · 4e5086b9
      Dmitriy Vyukov authored
      The implementation is hybrid active/passive spin/blocking mutex.
      The design minimizes amount of context switches and futex calls.
      The idea is that all critical sections in runtime are intentially
      small, so pure blocking mutex behaves badly causing
      a lot of context switches, thread parking/unparking and kernel calls.
      Note that some synthetic benchmarks become somewhat slower,
      that's due to increased contention on other data structures,
      it should not affect programs that do any real work.
