  2. clang-misexpect: Profile Guided Validation of Performance Annotations in LLVM

    This patch contains the basic functionality for reporting potentially
    incorrect usage of __builtin_expect() by comparing the developer's
    annotation against a collected PGO profile. A more detailed proposal and
    discussion appears on the CFE-dev mailing list
    ( and a
    prototype of the initial frontend changes appear here in D65300

    We revised the work in D65300 by moving the misexpect check into the
    LLVM backend, and adding support for IR and sampling based profiles, in
    addition to frontend instrumentation.

    We add new misexpect metadata tags to those instructions directly
    influenced by the llvm.expect intrinsic (branch, switch, and select)
    when lowering the intrinsics. The misexpect metadata contains
    information about the expected target of the intrinsic so that we can
    check against the correct PGO counter when emitting diagnostics, and the
    compiler's values for the LikelyBranchWeight and UnlikelyBranchWeight.
    We use these branch weight values to determine when to emit the
    diagnostic to the user.

    A future patch should address the comment at the top of
    LowerExpectIntrisic.cpp to hoist the LikelyBranchWeight and
    UnlikelyBranchWeight values into a shared space that can be accessed
    outside of the LowerExpectIntrinsic pass. Once that is done, the
    misexpect metadata can be updated to be smaller.

    In the long term, it is possible to reconstruct portions of the
    misexpect metadata from the existing profile data. However, we have
    avoided this to keep the code simple, and because some kind of metadata
    tag will be required to identify which branch/switch/select instructions
    are influenced by the use of llvm.expect

  4. Revert [git-llvm] Do not reinvent `@{upstream}`

    This reverts r371290 (git commit 7faffd544b16f851a632d6b8f93e3c8485ff34bb)

    The change wasnt NFC and broke some users' workflow. Reverting while figuring
    out the best alternative to move forward. (detail)

  6. Remove REQUIRES:shell from tests that pass for me on Windows

    I see in the history for some of these tests REQUIRES:shell was used as
    a way to disable tests on Windows because they are flaky there. I tried
    not to re-enable such tests, but it's possible that I missed some and
    this will re-enable flaky tests on Windows. If so, we should disable
    them with UNSUPPORTED:system-windows and add a comment that they are
    flaky there. So far as I can tell, the lit internal shell is capable of
    running all of these tests, and we shouldn't use REQUIRES:shell as a
    proxy for Windows. (detail)

  15. [Windows] Replace TrapUnreachable with an int3 insertion pass

    This is an alternative to D66980, which was reverted. Instead of
    inserting a pseudo instruction that optionally expands to nothing, add a
    pass that inserts int3 when appropriate after basic block layout.
