  1. [x86] move vector shift tests for PR37428; NFC

    As suggested in the post-commit thread for rL363392 - it's
    wasteful to have so many runs for larger tests. AVX1/AVX2
    is what shows the diff and probably what matters most going
    forward. (detail)

  2. GlobalISel: Avoid producing Illegal copies in RegBankSelect

    Avoid producing illegal register bank copies for reg_sequence and
    phi. The default implementation assumes it is possible to pick any
    operand's bank and use that for the result, introducing a copy for
    operands with a different bank. This does not check for illegal
    copies. It is not legal to introduce a VGPR->SGPR copy, so any VGPR
    operand requires the result to be a VGPR.

    The changes in getInstrMappingImpl aren't strictly necessary, since
    AMDGPU now just bypasses this for reg_sequence/phi. This could be
    replaced with an assert in case other targets run into this. It is
    currently responsible for producing the error for unsatisfiable
    copies, but this will be better served with a verifier check.

    For phis, for now assume any undetermined operands must be
    VGPRs. Eventually, this needs to be able to defer mapping these
    operations. This also does not yet have a way to check for whether the
    block is in a divergent region. (detail)

  5. [Attributor] Introduce bit-encodings for abstract states

    The IntegerState, and its sepecialization BooleanState, can be used to
    simplify the implementation of abstract attributes. The two abstract
    state implementations provide storage and helpers to deal with bit-wise
    encoded state.

  6. AMDGPU: Fold readlane intrinsics of constants

    I'm not 100% sure about this, since I'm worried about IR transforms
    that might end up introducing divergence downstream once replaced with
    a constant, but I haven't come up with an example yet. (detail)

  9. Revert "Revert r363377: [yaml2obj] - Allow setting custom section types for implicit sections."

    LLD test case will be fixed in a following commit.

    Original commit message:

    [yaml2obj] - Allow setting custom section types for implicit sections.

    We were hardcoding the final section type for sections that
    are usually implicit. The patch fixes that.

    This also fixes a few issues in existent test cases and removes
    one precompiled object.

  13. RegBankSelect: Remove checks for invalid mappings

    Avoid a check for valid and a set of redundant asserts. The place

    this. (detail)

  16. [lit] Fix UnicodeEncodeError when test commands contain non-ASCII chars

    Ensure that the bash script written by lit TestRunner is open with UTF-8
    encoding when using Python 3.  Otherwise, attempt to write non-ASCII
    characters causes UnicodeEncodeError.  This happened e.g. with
    the following LLD test:

    UNRESOLVED: lld :: ELF/format-binary-non-ascii.s (657 of 2119)
    ******************** TEST 'lld :: ELF/format-binary-non-ascii.s' FAILED ********************

  17. [MCA] Ignore invalid processor resource writes of zero cycles. NFCI

    In debug mode, the tool also raises a warning and prints out a message which
    helps identify the problematic MCWriteProcResEntry from the scheduling class.
    This message would have been useful to have when triaging PR42282. (detail)

  22. [docs][llvm-dwarfdump] Make the --show-parents and --show-children help text and docs more consistent and correct

    The docs and help text for --show-parents and --show-children were a bit
    inconsistent. The help text claimed they had an effect when "=<offset>"
    was used, whereas the doc said it had an effect when "--find" or
    "--name" were used. This change changes the doc to mention "=<offset>"
    and removes this reference from the help text, to avoid having a very
    long description in the help text (it still says "when selectively
    printing entries").

  30. [llvm-readobj] - Do not fail to dump the object which has wrong type of .shstrtab.

    Imagine we have object that has .shstrtab with type != SHT_STRTAB.
    In this case, we fail to dump the object, though GNU readelf dumps it without
    any issues and warnings.

    This patch fixes that. It adds a code to ELFDumper.cpp which is based on the implementation of getSectionName from the ELF.h:

    The difference is that all non critical errors are ommitted what allows us to
    improve the dumping on a tool side. Also, this opens a road for a follow-up that
    should allow us to dump the section headers, but drop the section names in case if .shstrtab is completely absent and/or broken.

  31. [ARM] MVE VPT Block Pass

    Initial commit of a new pass to create vector predication blocks, called VPT
    blocks, that are supported by the Armv8.1-M MVE architecture.

    This is a first naive implementation. I.e., for 2 consecutive predicated
    instructions I1 and I2, for example, it will generate 2 VPT blocks:


    A more optimal implementation would obviously put instructions in the same VPT
    block when they are predicated on the same condition and when it is allowed to
    do this:


    We will address this optimisation with follow up patches when the groundwork is
    in. Creating VPT Blocks is very similar to IT Blocks, which is the reason I
    added this to Thumb2ITBlocks.cpp. This allows reuse of the def use analysis
    that we need for the more optimal implementation.

    VPT blocks cannot be nested in IT blocks, and vice versa, and so these 2 passes
    cannot interact with each other. Instructions allowed in VPT blocks must
    be MVE instructions that are marked as VPT compatible.
