Abstract
Data races are among the most difficult to detect and costly bugs. Race detection
has been studied widely, but none of the existing tools satisfies the requirements
of high speed, detailed reports and wide availability at the same time. We describe
our attempt to create a tool that works fast, has detailed and understandable
reports and is available on a variety of platforms. The race detector is based on
our previous work, ThreadSanitizer, and the instrumentation is done using the LLVM
compiler. We show that applying compiler instrumentation and sampling reduces the
slowdown to less than 1.5x, fast enough for interactive use.
