New revision: 345449
URL: https://svnweb.freebsd.org/changeset/base/345449

Log:
  Pull in r356809 from upstream llvm trunk (by Eli Friedman):

    [ARM] Don't form "ands" when it isn't scheduled correctly.

    In r322972/r323136, the iteration here was changed to catch cases at
    the beginning of a basic block... but we accidentally deleted an
    important safety check.  Restore that check to the way it was.

    Fixes https://bugs.llvm.org/show_bug.cgi?id=41116

    Differential Revision: https://reviews.llvm.org/D59680

  This should fix "Assertion failed: (LiveCPSR && "CPSR liveness tracking
  is wrong!"), function UpdateCPSRUse" errors when building the devel/xwpe
  port for armv7.
