Changes
  1. [llvm-readobj] - Refactor the code.

    It's a straightforward refactoring that allows to simplify and encapsulate the code.

  2. [Clang] Pragma vectorize_width() implies vectorize(enable)

    Specifying the vectorization width was supposed to implicitly enable
    vectorization, except that it wasn't really doing this. It was only
    setting the vectorize.width metadata, but not vectorize.enable.

    This should fix PR27643.

  4. [RISCV] Add option aliases: -mcmodel=medany and -mcmodel=medlow

    RISC-V GCC use -mcmodel=medany and -mcmodel=medlow, but LLVM use
    -mcmodel=small and -mcmodel=medium.

    Add those two option aliases for provide same user interface between
    GCC and LLVM.

  5. [bugpoint] Add support for -Oz and properly enable -Os.

    This patch adds -Oz as option and also properly enables support for -Os.
    Currently, the existing check for -Os is dead, because the enclosing if
    only checks of O1, O2 and O3.

    There is still a difference between the -Oz pipeline compared to opt,
    but I have not been able to track that down yet.

  6. [RISCV] Define __riscv_cmodel_medlow and __riscv_cmodel_medany correctly

    RISC-V LLVM was only implement small/medlow code model, so it defined
    __riscv_cmodel_medlow directly without check.

    Now, we have medium/medany code model in RISC-V back-end, it should
    define according the actually code model.

  12. [X86] Split oversized vXi1 vector arguments and return values into scalars on avx512 targets.

    Previously we tried to split them into narrower v64i1 or v16i1
    pieces that each got promoted to vXi8 and then passed in a zmm
    or xmm register. But this crashes when you need to pass more
    pieces than available registers reserved for argument passing.

  21. [libFuzzer] Always print DSO map on Fuchsia libFuzzer launch

    Fuchsia doesn't have /proc/id/maps, so it relies on the kernel logging system
    to provide the DSO map to be able to symbolize in the context of ASLR. The DSO
    map is logged automatically on Fuchsia when encountering a crash or writing to
    the sanitizer log for the first time in a process. There are several cases
    where libFuzzer doesn't encounter a crash, e.g. on timeouts, OOMs, and when
    configured to print new PCs as they become covered, to name a few. Therefore,
    this change always writes to the sanitizer log on startup to ensure the DSO map
    is available in the log.

  36. [lit] Make internal diff work in pipelines

    When using lit's internal shell, RUN lines like the following
    accidentally execute an external `diff` instead of lit's internal
    `diff`:

    ```
    # RUN: program | diff file -
    # RUN: not diff file1 file2 | FileCheck %s
    ```

    Such cases exist now, in `clang/test/Analysis` for example.  We are
    preparing patches to ensure lit's internal `diff` is called in such
    cases, which will then fail because lit's internal `diff` cannot
    currently be used in pipelines and doesn't recognize `-` as a
    command-line option.

    To enable pipelines, this patch moves lit's `diff` implementation into
    an out-of-process script, similar to lit's `cat` implementation.  A
    follow-up patch will implement `-` to mean stdin.

  47. [PGO] Use linkonce_odr linkage for __profd_ variables in comdat groups

    This fixes relocations against __profd_ symbols in discarded sections,
    which is PR41380.

    In general, instrumentation happens very early, and optimization and
    inlining happens afterwards. The counters for a function are calculated
    early, and after inlining, counters for an inlined function may be
    widely referenced by other functions.

    For C++ inline functions of all kinds (linkonce_odr &
    available_externally mainly), instr profiling wants to deduplicate these
    __profc_ and __profd_ globals. Otherwise the binary would be quite
    large.

    I made __profd_ and __profc_ comdat in r355044, but I chose to make
    __profd_ internal. At the time, I was only dealing with coverage, and in
    that case, none of the instrumentation needs to reference __profd_.
    However, if you use PGO, then instrumentation passes add calls to
    __llvm_profile_instrument_range which reference __profd_ globals. The
    solution is to make these globals externally visible by using
    linkonce_odr linkage for data as was done for counters.

    This is safe because PGO adds a CFG hash to the names of the data and
    counter globals, so if different TUs have different globals, they will
    get different data and counter arrays.

  49. Implement std::condition_variable via pthread_cond_clockwait() where available

    std::condition_variable is currently implemented via
    pthread_cond_timedwait() on systems that use pthread. This is
    problematic, since that function waits by default on CLOCK_REALTIME
    and libc++ does not provide any mechanism to change from this
    default.

    Due to this, regardless of if condition_variable::wait_until() is
    called with a chrono::system_clock or chrono::steady_clock parameter,
    condition_variable::wait_until() will wait using CLOCK_REALTIME. This
    is not accurate to the C++ standard as calling
    condition_variable::wait_until() with a chrono::steady_clock parameter
    should use CLOCK_MONOTONIC.

    This is particularly problematic because CLOCK_REALTIME is a bad
    choice as it is subject to discontinuous time adjustments, that may
    cause condition_variable::wait_until() to immediately timeout or wait
    indefinitely.

    This change fixes this issue with a new POSIX function,
    pthread_cond_clockwait() proposed on
    http://austingroupbugs.net/view.php?id=1216. The new function is
    similar to pthread_cond_timedwait() with the addition of a clock
    parameter that allows it to wait using either CLOCK_REALTIME or
    CLOCK_MONOTONIC, thus allowing condition_variable::wait_until() to
    wait using CLOCK_REALTIME for chrono::system_clock and CLOCK_MONOTONIC
    for chrono::steady_clock.

    pthread_cond_clockwait() is implemented in glibc (2.30 and later) and
    Android's bionic (Android API version 30 and later).

    This change additionally makes wait_for() and wait_until() with clocks
    other than chrono::system_clock use CLOCK_MONOTONIC.<Paste> (detail/ViewSVN)

  55. [SimplifyCFG] FoldTwoEntryPHINode(): consider *total* speculation cost, not per-BB cost

    Summary:
    Previously, if the threshold was 2, we were willing to speculatively
    execute 2 cheap instructions in both basic blocks (thus we were willing
    to speculatively execute cost = 4), but weren't willing to speculate
    when one BB had 3 instructions and other one had no instructions,
    even thought that would have total cost of 3.

    This looks inconsistent to me.
    I don't think `cmov`-like instructions will start executing
    until both of it's inputs are available: https://godbolt.org/z/zgHePf
    So i don't see why the existing behavior is the correct one.

    Also, let's add it's own `cl::opt` for this threshold,
    with default=4, so it is not stricter than the previous threshold:
    will allow to fold when there are 2 BB's each with cost=2.
    And since the logic has changed, it will also allow to fold when
    one BB has cost=3 and other cost=1, or there is only one BB with cost=4.

    This is an alternative solution to D65148:
    This fix is mainly motivated by `signbit-like-value-extension.ll` test.
    That pattern comes up in JPEG decoding, see e.g.
    `Figure F.12 – Extending the sign bit of a decoded value in V`
    of `ITU T.81` (JPEG specification).
    That branch is not predictable, and it is within the innermost loop,
    so the fact that that pattern ends up being stuck with a branch
    instead of `select` (i.e. `CMOV` for x86) is unlikely to be beneficial.

    This has great results on the final assembly (vanilla test-suite + RawSpeed): (metric pass - D67240)
    | metric                                 |     old |     new | delta |      % |
    | x86-mi-counting.NumMachineFunctions    |   37720 |   37721 |     1 |  0.00% |
    | x86-mi-counting.NumMachineBasicBlocks  |  773545 |  771181 | -2364 | -0.31% |
    | x86-mi-counting.NumMachineInstructions | 7488843 | 7486442 | -2401 | -0.03% |
    | x86-mi-counting.NumUncondBR            |  135770 |  135543 |  -227 | -0.17% |
    | x86-mi-counting.NumCondBR              |  423753 |  422187 | -1566 | -0.37% |
    | x86-mi-counting.NumCMOV                |   24815 |   25731 |   916 |  3.69% |
    | x86-mi-counting.NumVecBlend            |      17 |      17 |     0 |  0.00% |

    We significantly decrease basic block count, notably decrease instruction count,
    significantly decrease branch count and very significantly increase `cmov` count.

    Performance-wise, unsurprisingly, this has great effect on
    target RawSpeed benchmark. I'm seeing 5 **major** improvements:

    That being said, it's always best-effort, so there will likely
    be cases where this worsens things.

  56. [clangd] Simplify semantic highlighting visitor

    Summary:
    - Functions to compute highlighting kinds for things are separated from
      the ones that add highlighting tokens.
      This keeps each of them more focused on what they're doing: getting
      locations and figuring out the kind of the entity, correspondingly.

    - Less special cases in visitor for various nodes.

    This change is an NFC.

  57. [InstCombine] remove unneeded one-use checks for icmp fold

    Related folds were added in:
    rL125734
    ...the code comment about register pressure is discussed in
    more detail in:
    https://bugs.llvm.org/show_bug.cgi?id=2698

    But 10 years later, perf testing bzip2 with this change now
    shows a slight (0.2% average) improvement on Haswell although
    that's probably within test noise.

    Given that this is IR canonicalization, we shouldn't be worried
    about register pressure though; the backend should be able to
    adjust for that as needed.

    This is part of solving PR43310 the theoretically right way:
    https://bugs.llvm.org/show_bug.cgi?id=43310
    ...ie, if we don't cripple basic transforms, then we won't
    need to add special-case code to detect larger patterns.

    rL371940 and rL371981 are related patches in this series. (detail/ViewSVN)

  63. [ExecutionEngine] Don't dereference a dyn_cast result. NFCI.

    The static analyzer is warning about potential null dereferences of dyn_cast<> results - in these cases we can safely use cast<> directly as we know that these cases should all be the correct type, which is why its working atm and anyway cast<> will assert if they aren't. (detail/ViewSVN)

  65. [LV] Add ARM MVE tail-folding tests

    Now that the vectorizer can do tail-folding (rL367592), and the ARM backend
    understands MVE masked loads/stores (rL371932), it's time to add the MVE
    tail-folding equivalent of the X86 tests that I added. (detail/ViewSVN)

  66. [SystemZ]  Call erase() on the right MBB in SystemZTargetLowering::emitSelect()

    Since MBB was split *before* MI, the MI(s) will reside in JoinMBB (MBB) at
    the point of erasing them, so calling StartMBB->erase() is actually wrong,
    although it is "working" by all appearances.
