[fuzzer] Script to detect unbalanced allocation in -trace_malloc output Reviewers: kcc Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D39466 llvm-svn: 317119

// FIXME: This test infinite loops on darwin because it crashes
// printing a stack trace repeatedly
[libfuzzer] Enable trace-malloc-unballanced.test on Windows. Summary: Enables trace-malloc-unbalanced.test on Windows, fixing two problems it had with Windows before. The first fix is specifying python instead of relying on a script's shebang since they can't be used on Windows. The second fix is making the regex tolerate windows' implementation of the "%p" format string.

# Specify python because we can't use the shebang line on Windows.
[libFuzzer] [NFC] Prefix all run lines with %run This patch does not do anything, but paves the way for future changes, where %run command will be expanded into a script performing the testing on device. Differential Revision: https://reviews.llvm.org/D46553 llvm-svn: 332144

[Fuzzer][Test] Use %python substitution for trace-malloc-unbalanced.test This test was found to fail for some of our downstream builds, on computers where python was not on the default $PATH. Therefore add a %python substitution to use sys.executable, based on similar solutions for python calls in tests elsewhere in LLVM. Differential Revision: https://reviews.llvm.org/D96799
