Subproject Builds

Revision: 302613
  1. [Core] Make parallel algorithms match C++ Parallelism TS.

    Differential Revision: (detail/ViewSVN)

  2. [CodeGen] Don't require AA in TwoAddress at -O0.

    This is a follow-up to r302611, which moved an -O0 computation of DT
    from SDAGISel to TwoAddress.

    Don't use it here either, and avoid computing it completely.  The only
    use was forwarding the analysis as an optional argument to utility

  3. [CodeGen] Don't require AA in SDAGISel at -O0.

    Before r247167, the pass manager builder controlled which AA
    implementations were used, exporting them all in the AliasAnalysis
    analysis group.

    Now, AAResultsWrapperPass always uses BasicAA, but still uses other AA
    implementations if made available in the pass pipeline.

    But regardless, SDAGISel is required at O0, and really doesn't need to
    be doing fancy optimizations based on useful AA results.

    Don't require AA at CodeGenOpt::None, and only use it otherwise.

    This does have a functional impact (and one testcase is pessimized
    because we can't reuse a load).  But I think that's desirable no matter

    Note that this alone doesn't result in less DT computations: TwoAddress
    was previously able to reuse the DT we computed for SDAG.  That will be
    fixed separately.

  4. [CodeGen] Compute DT/LI lazily in SafeStackLegacyPass. NFC.

    We currently require SCEV, which requires DT/LI.  Those are expensive to
    compute, but the pass only runs for functions that have the safestack

    Compute DT/LI to build SCEV lazily, only when the pass is actually going
    to transform the function.

  5. [CodeGen] Split SafeStack into a LegacyPass and a utility. NFC.

    This lets the pass focus on gathering the required analyzes, and the
    utility class focus on the transformation.

    Differential Revision: (detail/ViewSVN)
    by ab
  6. [CodeGen] Add an -O0 backend pipeline test. NFC.

    This should hopefully makes changes to the O0 pipeline obvious; it's
    easy to require expensive passes, and this helps make informed

    Case in point: in the few weeks separating the time when I initially
    wrote this patch to the time when I committed, the test regressed as
    r302103 added another use of DT! (detail/ViewSVN)
