This commit adds a static analysis checker to verify the correct usage of the MPI API in C and C++. This version updates the reverted r271981 to fix a memory corruption found by the ASan bots. Three path-sensitive checks are included: - Double nonblocking: Double request usage by nonblocking calls without intermediate wait - Missing wait: Nonblocking call without matching wait. - Unmatched wait: Waiting for a request that was never used by a nonblocking call Examples of how to use the checker can be found at https://github.com/0ax1/MPI-Checker A patch by Alexander Droste! Reviewers: zaks.anna, dcoughlin Differential Revision: http://reviews.llvm.org/D21081 llvm-svn: 272529
