  1. [ThinLTO] only emit used or referenced CFI records to index

    distributed ThinLTO indices to implement indirect function call
    checking.  This change causes us to only emit entries for functions
    that are either defined or used by the module we're writing the index
    for (instead of all functions in the combined index), which can make
    the indices substantially smaller.

    Fixes PR42378.

  2. Add a transform pass to make the executable semantics of poison explicit in the IR

    Implements a transform pass which instruments IR such that poison semantics are made explicit. That is, it provides a (possibly partial) executable semantics for every instruction w.r.t. poison as specified in the LLVM LangRef. There are obvious parallels to the sanitizer tools, but this pass is focused purely on the semantics of LLVM IR, not any particular source language.

    The target audience for this tool is developers working on or targetting LLVM from a frontend. The idea is to be able to take arbitrary IR (with the assumption of known inputs), and evaluate it concretely after having made poison semantics explicit to detect cases where either a) the original code executes UB, or b) a transform pass introduces UB which didn't exist in the original program.

    At the moment, this is mostly the framework and still needs to be fleshed out. By reusing existing code we have decent coverage, but there's a lot of cases not yet handled. What's here is good enough to handle interesting cases though; for instance, one of the recent LFTR bugs involved UB being triggered by integer induction variables with nsw/nuw flags would be reported by the current code.

    (See comment in PoisonChecking.cpp for full explanation and context)

  3. Try to appease the Windows build bots.

    Several of the conditonal operators commited in llvm-svn: 365524 fail to compile
    on the windows buildbots. Converting to an if and early return to try to fix. (detail/ViewSVN)

  6. [clangd] Rewrite of logic to rebuild the background index serving structures.

    Previously it was rebuilding every 5s by default, which was much too frequent
    in the long run - the goal was to provide an early build. There were also some
    bugs. There were also some bugs, and a dedicated thread was used in production
    but not tested.

    - rebuilds are triggered by #TUs built, rather than time. This should scale
       more sensibly to fast vs slow machines.
    - there are two separate indexed-TU thresholds to trigger index build: 5 TUs
       for the first build, 100 for subsequent rebuilds.
    - rebuild is always done on the regular indexing threads, and is affected by
       blockUntilIdle. This means unit/lit tests run the production configuration.
    - fixed a bug where we'd rebuild after attempting to load shards, even if there
       were no shards.
    - the BackgroundIndexTests don't really test the subtleties of the rebuild
       policy (for determinism, we call blockUntilIdle, so rebuild-on-idle is enough
       to pass the tests). Instead, we expose the rebuilder as a separate class and
       have fine-grained tests for it.

  11. [Object][XCOFF] Add support for 64-bit file header and section header dumping.

    Adds a readobj dumper for 32-bit and 64-bit section header tables, and extend
    support for the file-header dumping to include 64-bit object files. Also
    refactors the binary file parsing to be done in a helper function in an attempt
    to cleanup error handeling.

  12. [InstCombine] add tests for trunc(load); NFC

    I'm not sure if transforming any of these is valid as
    a target-independent fold, but we might as well have
    a few tests here to confirm or deny our position. (detail/ViewSVN)

  13. [clangd] Show documentation in hover, and fetch docs from index if needed.

    I assume showing docs is going to be part of structured hover rendering, but
    it's unclear whether that's going to make clangd 9 so this is low-hanging fruit.

    (Also fixes a bug uncovered in FormattedString's plain text output: need blank
    lines when text follows codeblocks)
