  3. [llvm] Expose DWARFDebugLine::LineTable::getFileNameEntry

    This is useful for scenarios where Prologue was directly used and DWARF
    5 awareness is required. The current alternative would be to either
    duplicate the logic in getFileNameEntry, or to use getFileNameByIndex.
    The latter isn't quite an in-place replacement - it performs some
    processing, and it produces a string instead of a StringRef, meaning
    the caller needs to handle its lifetime.

  8. [clang-scan-deps] initial outline of the tool that runs preprocessor to find
    dependencies over a JSON compilation database

    This commit introduces an outline for the clang-scan-deps tool that will be
    used to implement fast dependency discovery phase using implicit modules for
    explicit module builds.

    The initial version of the tool works by computing non-modular header dependencies
    for files in the compilation database without any optimizations
    (i.e. without source minimization from r362459).
    The tool spawns a number of worker threads to run the clang compiler workers in parallel.

    The immediate goal for clang-scan-deps is to create a ClangScanDeps library
    which will be used to build up this tool to use the source minimization and
    caching multi-threaded filesystem to implement the optimized non-incremental
    dependency scanning phase for a non-modular build. This will allow us to do
    benchmarks and comparisons for performance that the minimization and caching give us

    Note that this is *not* what MSVC does: MSVC has not yet implemented C++

    by rksimon
  30. [SCEV] Teach computeSCEVAtScope benefit from one-input Phi. PR39673

    SCEV does not propagate arguments through one-input Phis so as to make it easy for the SCEV expander (and related code) to preserve LCSSA.  It's not entirely clear this restriction is neccessary, but for the moment it exists.   For this reason, we don't analyze single-entry phi inputs.  However it is possible that when an this input leaves the loop through LCSSA Phi, it is a provable constant.  Missing that results in an order of optimization issue in loop exit value rewriting where we miss some oppurtunities based on order in which we visit sibling loops.

    This patch teaches computeSCEVAtScope about this case. We can generalize it later, but so far we can only replace LCSSA Phis with their constant loop-exiting values.  We should probably also add similiar logic directly in the SCEV construction path itself.

    As discussed on D62910, we need to check whether particular types of memory access are allowed, not just their alignment/address-space.

    This NFC patch adds a MachineMemOperand::Flags argument to allowsMemoryAccess and allowsMisalignedMemoryAccesses, and wires up calls to pass the relevant flags to them.

  46. LoopDistribute/LAA: Respect convergent

    This case is slightly tricky, because loop distribution should be

    checks don't need to be introduced, this should be OK. This is further
    complicated by the fact that LoopDistribute partially ignores if LAA
    says that vectorization is safe, and then does its own runtime pointer
    legality checks.

    Note this pass still does not handle noduplicate correctly, as this
    should always be forbidden with it. I'm not going to bother trying to
    fix it, as it would require more effort and I think noduplicate should
    be removed. (detail/ViewSVN)

  57. [ARM] Implement TTI::isHardwareLoopProfitable
    Implement the backend target hook to drive the HardwareLoops pass.
    The low-overhead branch extension for Arm M-class cores is flexible
    enough that we don't have to ensure correctness at this point, except
    checking that the loop counter variable can be stored in LR - a
    32-bit register. For it to be profitable, we want to avoid loops that
    contain function calls, or any other instruction that alters the PC.
    This implementation uses TargetLoweringInfo, to query type and
    operation actions, looks at intrinsic calls and also performs some
    manual checks for remainder/division and FP operations.
    I think this should be a good base to start and extra details can be
    filled out later.

  64. [ThinLTO]LTO]Legacy] Fix dependent libraries support by adding querying of the IRSymtab

    Dependent libraries support for the legacy api was committed in a
    broken state (see: This was missed
    due to the painful nature of having to integrate the changes into a
    linker in order to test. This change implements support for dependent
    libraries in the legacy LTO api:

    - I have removed the current api function, which returns a single
    string, and   added functions to access each dependent library
    specifier individually.

    - To reduce the testing pain, I have made the api functions as thin as
    possible to   maximize coverage from llvm-lto.

    - When doing ThinLTO the system linker will load the modules lazily
    when scanning   the input files. Unfortunately, when modules are
    lazily loaded there is no access   to module level named metadata. To
    fix this I have added api functions that allow   querying the IRSymtab
    for the dependent libraries. I hope to expand the api in the   future
    so that, eventually, all the information needed by a client linker
    during   scan can be retrieved from the IRSymtab.

  72. [AVR] Fix the 'avr-tiny.ll' and 'avr25.ll' subtarget feature tests

    When these tests were originally written, the middle end would introduce
    an unnecessary copy from r24:r23->GPR16->r24:r23, and these tests
    mistakenly relied on it.

    The most optimal codegen for the functions in the test cases before this patch
    would be NOPs. This is because the first i16 argument always gets the same register
    allocation as an i16 return value in the AVR calling convention.

    These tests broke in r362963 when the codegen was improved and the
    redundant copy was eliminated. After this, the test functions
    were lowered to their optimal form - a 'ret' and nothing else.

    This patch prepends an extra i16 operand to each of the test functions
    so that a 16-bit copy must be inserted for the program to be correct. (detail/ViewSVN)

    which has higher priority when the platform is PowerPC on Linux. They are mainly developed by Steven Munroe,
    with contributions from Paul Clarke, Bill Schmidt, Jinsong Ji and Zixuan Wu.

    It's a follow-up patch of D62121.

  82. Apply [[nodebug]] to typedefs throughout the STL.

    When applied to a typedef or alias template, the [[nodebug]] attribute
    makes the typedef transparent to the debugger, so instead of seeing
    allocator<remove_reference<void(&)()>, void()>::_Target` you see
    `void(&)()` as the type of the variable in your debugger.

    Removing all this SFINAE noise from debug info has huge binary size
    wins, in addition to improving the readability.

    For now this change is on by default. Users can override it by
    specifying -D_LIBCPP_NODEBUG_TYPE= (detail/ViewSVN)

  83. [X86] [ABI] Fix i386 ABI "__m64" type bug

    According to System V i386 ABI: the  __m64 type paramater and return
    value are passed by MMX registers. But current implementation treats
    __m64 as i64 which results in parameter passing by stack and returning
    by EDX and EAX.

    This patch fixes the bug (
    for Linux and NetBSD.

  86. Fix a bug in getSCEVAtScope w.r.t. non-canonical loops

    The issue is that if we have a loop with multiple predecessors outside the loop, the code was expecting to merge them and only return if equal, but instead returned the first one seen.

    I have no idea if this actually tripped anywhere.  I noticed it by accident when reading the code and have no idea how to go about constructing a test case. (detail/ViewSVN)

  88. Add documentation and tests for Clangs C++11 extensions in C++03.

    As we gear up to drop support for GCC in C++03, we should make clear
    what our C++03 mode is, the C++11 extensions it provides,
    and the C++11 extensions it depends on.

    The section of this document discussing user-facing extensions has
    been left blank while the community discusses new directions. For now
    it's just a warning to users.

    Additionally, the document contains examples of how these extensions
    should be used and why. For example, using alias templates over class
    templates. (detail/ViewSVN)

  89. Generalize icmp matching in IndVars' eliminateTrunc

  91. [Analysis] add isSplatValue() for vectors in IR

    We have the related getSplatValue() already in IR (see code just above the proposed addition).
    But sometimes we only need to know that the value is a splat rather than capture the splatted
    scalar value. Also, we have an isSplatValue() function already in SDAG.

    Motivation - recent bugs that would potentially benefit from improved splat analysis in IR:

  94. [docs] Add "GNU binutils Replacements" section to command guide

    This splits out a section in the command guide for llvm tools that can be used as replacements for GNU tools. For pages that didn't exist, I added stub pages that can be individually filled in by followup patches.

    Tested by running `ninja docs-llvm-html` and inspecting locally.

  98. [scudo][standalone] Unmap memory in tests

    The more tests are added, the more we are limited by the size of the
    address space on 32-bit. Implement `unmapTestOnly` all around (like it
    is in sanitzer_common) to be able to free up some memory.
    This is not intended to be a proper "destructor" for an allocator, but
    allows us to not fail due to having no memory left.

    Instead, mark the MemorySSA analysis as preserved by each pass that does
