  2. [Remarks] Allow the RemarkStreamer to be used directly with a stream

    The filename in the RemarkStreamer should be optional to allow clients

    This introduces a new overload of `setupOptimizationRemarks`, and avoids
    enforcing the presence of a filename at different places. (detail/ViewSVN)

  3. [Timers] Fix printing some `-ftime-report` sections twice. Fixes PR40328.

    Starting from r324788 timer groups aren't cleared automatically when
    printed out. As a result some timer groups were printed one more time.
    For example, "Pass execution timing report" was printed again in
    `ManagedStatic<PassTimingInfo>` destructor, "DWARF Emission" in
    `ManagedStatic<Name2PairMap> NamedGroupedTimers` destructor.

    Fix by clearing timer groups manually.

  4. [PGO] Change hardcoded thresholds for cold/inlinehint to use summary

    The PGO counter reading will add cold and inlinehint (hot) attributes
    to functions that are very cold or hot. This was using hardcoded
    thresholds, instead of the profile summary cutoffs which are used in
    other hot/cold detection and are more dynamic and adaptable. Switch
    to using the summary-based cold/hot detection.

    The hardcoded limits were causing some code that had a medium level of
    hotness (per the summary) to be incorrectly marked with a cold
    attribute, blocking inlining.

  6. [ARM] VFPv2 only supports 16 D registers.

    r361845 changed the way we handle "D16" vs. "D32" targets; there used to
    be a negative "d16" which removed instructions from the instruction set,
    and now there's a "d32" feature which adds instructions to the
    instruction set.  This is good, but there was an oversight in the
    implementation: the behavior of VFPv2 was changed.  In particular, the
    "vfp2" feature was changed to imply "d32". This is wrong: VFPv2 only
    supports 16 D registers.

    In practice, this means if you specify -mfpu=vfpv2, the compiler will
    generate illegal instructions.

    This patch gets rid of "vfp2d16" and "vfp2d16sp", and fixes "vfp2" and
    "vfp2sp" so they don't imply "d32".

  9. [PGO] Don't use comdat groups for counters & data on COFF

    For COFF, a comdat group is really a symbol marked
    IMAGE_COMDAT_SELECT_ANY and zero or more other symbols marked
    IMAGE_COMDAT_SELECT_ASSOCIATIVE. Typically the associative symbols in
    the group are not external and are not referenced by other TUs, they are
    things like debug info, C++ dynamic initializers, or other section
    registration schemes. The Visual C++ linker reports a duplicate symbol
    error for symbols marked IMAGE_COMDAT_SELECT_ASSOCIATIVE even if they
    would be discarded after handling the leader symbol.

  13. Ignore exception specifier mismatch when merging redeclarations

    Exception specifiers are now part of the function type in C++17.
    Normally, it is illegal to redeclare the same function or specialize a
    template with a different exception specifier, but under
    -fms-compatibility, we accept it with a warning. Without this change,
    the function types would not match due to the exception specifier, and
    clang would claim that the types were "incompatible". Now we emit the
    warning and merge the redeclaration as we would in C++14 and earlier.

    Fixes PR42842, which is about compiling _com_ptr_t in C++17.

  14. [AArch64][GlobalISel] Support -tailcallopt

    This adds support for `-tailcallopt` tail calls to CallLowering. This
    piggy-backs off the changes from D67577, since doing it without a bit of
    refactoring gets extremely ugly.

    Support is basically ported from AArch64ISelLowering. The main difference here
    is that tail calls in `-tailcallopt` change the ABI, so there's some extra
    bookkeeping for the stack.

    Show that we are correctly lowering these by updating tail-call.ll.

    Also show that we don't do anything strange in general by updating
    fastcc-reserved.ll, which passes `-tailcallopt`, but doesn't emit any tail

    I.e. the "sub of shift amounts" tells us how many bits will be left

  25. Data Dependence Graph Basics

    This is the first patch in a series of patches that will implement data dependence graph in LLVM. Many of the ideas used in this implementation are based on the following paper:
    D. J. Kuck, R. H. Kuhn, D. A. Padua, B. Leasure, and M. Wolfe (1981). DEPENDENCE GRAPHS AND COMPILER OPTIMIZATIONS.
    This patch contains support for a basic DDGs containing only atomic nodes (one node for each instruction). The edges are two fold: def-use edges and memory-dependence edges.
    The implementation takes a list of basic-blocks and only considers dependencies among instructions in those basic blocks. Any dependencies coming into or going out of instructions that do not belong to those basic blocks are ignored.

    The algorithm for building the graph involves the following steps in order:

      1. For each instruction in the range of basic blocks to consider, create an atomic node in the resulting graph.
      2. For each node in the graph establish def-use edges to/from other nodes in the graph.
      3. For each pair of nodes containing memory instruction(s) create memory edges between them. This part of the algorithm goes through the instructions in lexicographical order and creates edges in reverse order if the sink of the dependence occurs before the source of it.

    AnnotatedLine has a tree structure, and things like the body of a lambda will be

    will have an AnnotatedLine with a child:

        [&]() {};
         '- foo(a);

    Currently, when the `Cleaner` class analyzes the affected lines, it does not
    cleanup the lines' children nodes, which results in missed cleanup
    opportunities, like the lambda body in the example above.

    This revision extends the algorithm to visit children, thereby fixing the above problem.

    Also the narrowing loads/stores can be created with frame indices even though they do not accept SP as a register. We need in those cases to make sure we have an emergency register to use as the frame base, as SP can never be used.

    in which we perform these actions. First, the caches for the whole
    module are created, then we start to create abstract attributes.

    I don't have a unit test but the LLVM test suite exposes this problem.

  80. Add SemanticRanges to Clangd server.

    Adds Semantic Ranges capabilities to Clangd server.
    Also adds tests for running it via clangd server.

    This differs from the LSP spec as the spec needs this to be evaluated on multiple 'pos' and the expected output is an list of list of semantic ranges.
    This is majorly for multi cursor and assuming this is a rare thing, we don't want to optimize make things complicated just for this.
    This should be done in the LSP level by queueing one request per 'pos' in the input.

    LSP Spec:

  82. [SVE][MVT] Fixed-length vector MVT ranges

      * Reordered MVT simple types to group scalable vector types
      * New range functions in MachineValueType.h to only iterate over
        the fixed-length int/fp vector types.
      * Stopped backends which don't support scalable vector types from
        iterating over scalable types.

    We can do it now.

  94. [ARM] LE support in ConstantIslands

    The low-overhead branch extension provides a loop-end 'LE' instruction
    that performs no decrement nor compare, it just jumps backwards. This
    patch modifies the constant islands pass to try to insert LE
    instructions in place of a Thumb2 conditional branch, instead of
    shrinking it. This only happens if a cmp can be converted to a cbn/z
    and used to exit the loop.

  95. [LoopUnroll] Use LoopSize+1 as threshold, to allow unrolling loops matching LoopSize.

    We use `< UP.Threshold` later on, so we should use LoopSize + 1, to
    allow unrolling if the result won't exceed to loop size.

    Fixes PR43305.
