llvm: updated to 13.0.1

13.0.1:
Bug-fix release.

Log message:
revbump for icu and libffi

Log message:
llvm: update llvm and friends to 13.0.0

Tested on NetBSD-current and 9.1/amd64.

Also update packages tightly coupled to llvm, if new versions are
available.

Mark creduce, include-what-you-use, and zig broken (waiting for a
new release).

Changes:

Non-comprehensive list of changes in this release

    Windows Control-flow Enforcement Technology: the -ehcontguard
    option now emits valid unwind entrypoints which are validated
    when the context is being set during exception handling.

    Flang is now included in the binary packages released by LLVM.

    The debuginfo-test project has been renamed cross-project-tests
    and is now intended for testing components from multiple
    projects, not just debug information. The new “cross-project-tests”
    name replaces “debuginfo-test” in LLVM_ENABLE_PROJECTS, and a
    new check-cross-project-tests target has been added for running
    all tests in the project. The pre-existing check-debuginfo-
    test target remains for running just the debug information
    tests. (D95339 and D96513)

Changes to the LLVM IR

    The inalloca attribute now has a mandatory type field, similar
    to byval and sret.

    The opaque pointer type ptr has been introduced. It is still
    in the process of being worked on and should not be used yet.

    Using the legacy pass manager for the optimization pipeline is
    deprecated and will be removed after LLVM 14. In the meantime,
    only minimal effort will be made to maintain the legacy pass
    manager for the optimization pipeline.

Changes to building LLVM

    The build system now supports building multiple distributions,
    so that you can e.g. have one distribution containing just
    tools and another for libraries (to enable development). See
    Multi-distribution configurations for details.

Changes to the AArch64 Backend

    Introduced assembly support for Armv9-A’s Realm Management
    Extension (RME) and Scalable Matrix Extension (SME).

    Produce proper cross-section relative relocations on COFF

    Fixed the calling convention on Windows for variadic functions
    involving floats in the fixed arguments

Changes to the ARM Backend

    Produce proper cross-section relative relocations on COFF

Changes to the Hexagon Target

    The Hexagon target now supports V68/HVX ISA.

Changes to the C API

    The C API functions LLVMGetAlignment and LLVMSetAlignment now
    allow changing alignment on atomicrmw and cmpxchg instructions

    A new entry LLVMDIArgListMetadataKind was added to the
    LLVMMetadataKind enum, representing DIArgLists (D88175)

    Type attributes have been added to LLVM-C, introducing
    LLVMCreateTypeAttribute, LLVMGetTypeAttributeValue and
    LLVMIsTypeAttribute. (D977763’)

    The LTO_API_VERSION was bumped to 28, introducing a new function
    lto_set_debug_options for parsing LTO debug options (D92611)

    LLVMJITTargetSymbolFlags was renamed to LLVMJITSymbolTargetFlags
    (rG8d718a0bff73af066675a6258c01307937c33cf9)

    The C API received support for creating custom ORCv2
    MaterializationUnits and APIs to retrieve an LLJIT instance’s
    linking layers. An ABI breaking change for LLVMOrcAbsoluteSymbols
    was introduced to make it consistent with
    LLVMOrcCreateCustomMaterializationUnit.
    (rGc8fc5e3ba942057d6c4cdcd1faeae69a28e7b671)

    The C API received support for adding ORCv2 object buffers
    directly to an object layer.
    (rG7b73cd684a8d5fb44d34064200f10e2723085c33)

    A breaking change to LLVMGetInlineAsm was introduced, adding
    a ninth argument LLVMBool CanThrow (D95745)

    The C API received support for calling into the new pass manager.
    (D102136)

    The C API function LLVMIntrinsicCopyOverloadedName has been
    deprecated. Please migrate to LLVMIntrinsicCopyOverloadedName2
    which takes an extra module argument and which also handles
    unnamed types. (D99173)

    The C API received support for dumping objects from ORCv2
    (rGcec8e69f01c3374cb38c6683058381b96fab8f89)

    A breaking change to LLVMOrcObjectTransformLayerTransformFunction
    was introduced, changing the order of the function pointer’s
    arguments. (rG8962c68ad007a525f9daa987c99eda57e0d0069a)

    The C API received support for accessing utilities from the
    LLJIT IRTransformLayer and ThreadSafeModule classes. (D103855)

    The C API received support for creating lazy-export
    MaterializationUnits (D104672)

    The C API function LLVMPassBuilderOptionsSetCoroutines was
    removed because couroutine passes have been enabled by default.
    (D105877)

    comdat noduplicates was renamed to comdat nodeduplicate and as
    a result, LLVMNoDuplicatesComdatSelectionKind was renamed to
    LLVMNoDeduplicateComdatSelectionKind. (D106319)

Changes to the FastISel infrastructure

    FastISel no longer tracks killed registers, and instead leaves
    this to the register allocator. This means that hasTrivialKill()
    is removed, as well as the OpNIsKill parameters to the fastEmit_*()
    family of functions.

Changes to the LLVM tools

    The options --build-id-link-{dir,input,output} have been deleted.
    (D96310)

    Support for in-order processors has been added to llvm-mca.
    (D94928)

    llvm-objdump supports -M {att,intel} now. --x86-asm-syntax is
    a deprecated internal option which will be removed in LLVM
    14.0.0. (D101695)

    The llvm-readobj short aliases -s (previously --sections) and
    -t (previously --syms) have been changed to --syms and
    --section-details respectively, to match llvm-readelf. (D105055)

    The llvm-nm short aliases -M (--print-armap), -U (--defined-only),
    and -W (--no-weak) are now deprecated. Use the long form versions
    instead. The alias --just-symbol-name is now deprecated in
    favor of --format=just-symbols and -j. (D105330)

    In lli the default JIT engine switched from MCJIT (-jit-kind=mcjit)
    to ORC (-jit-kind=orc). (D98931)

    llvm-rc got support for invoking Clang to preprocess its input.
    (D100755)

    llvm-rc got a GNU windres compatible frontend, llvm-windres.
    (D100756)

    llvm-ml has improved compatibility with MS ml.exe, managing to
    assemble more asm files.

Changes to LLDB

    LLDB executable is now included in pre-built LLVM binaries.

    LLDB now includes full featured support for AArch64 SVE register
    access.

    LLDB now supports AArch64 Pointer Authentication, allowing
    stack unwind with signed return address.

    LLDB now supports debugging programs on AArch64 Linux that use
    memory tagging (MTE).

    Added memory tag read and memory tag write commands.

    The memory region command will note when a region has memory
    tagging enabled.

    Synchronous and asynchronous tag faults are recognised.

    Synchronous tag faults have memory tag annotations in addition
    to the usual fault address.

Improvements to clangd

Performance

clangd’s memory usage is significantly reduced on most Linux systems. In \ 
particular, memory usage should not increase dramatically over time.

The standard allocator on most systems is glibc’s ptmalloc2, and it creates \ 
disproportionately large heaps when handling clangd’s allocation patterns. By \ 
default, clangd will now periodically call malloc_trim to release free pages on \ 
glibc systems.

Users of other allocators (such as jemalloc or tcmalloc) on glibc systems can \ 
disable this using --malloc_trim=0 or the CMake flag -DCLANGD_MALLOC_TRIM=0.

Added the $/memoryUsage request: an LSP extension. This provides a breakdown of \ 
the memory clangd thinks it is using (excluding malloc overhead etc). The clangd \ 
VSCode extension supports showing the memory usage tree.
Parsing and selection

Improved navigation of broken code in C using Recovery AST. (This has been \ 
enabled for C++ since clangd 11).
Types are understood more often in broken code. (This is the first release where \ 
Recovery AST preserves speculated types).
Heuristic resolution for dependent names in templates.
Code completion

Higher priority for symbols that were already used in this file, and symbols \ 
from namespaces mentioned in this file. (Estimated 3% accuracy improvement)

Introduced a ranking algorithm trained on snippets from a large C++ codebase. \ 
Use the flag --ranking-model=decision_forest to try this (Estimated 6% accuracy \ 
improvement). This mode is likely to become the default in future.

Note: this is a generic model, not specialized for your code. clangd does not \ 
collect any data from your code to train code completion.

Signature help works with functions with template-dependent parameter types.
Go to definition

Selecting an auto or decltype keyword will attempt to navigate to a definition \ 
of the deduced type.
Improved handling of aliases: navigate to the underlying entity more often.
Better understanding of declaration vs definition for Objective-C classes and \ 
protocols.
Selecting a pure-virtual method shows its overrides.
Find references

Indexes are smarter about not returning stale references when code is deleted.
References in implementation files are always indexed, so results should be more \ 
complete.
Find-references on a virtual method shows references to overridden methods.
New navigation features

Call hierarchy (textDocument/callHierarchy) is supported. Only incoming calls \ 
are available.
Go to implementation (textDocument/implementation) is supported on abstract \ 
classes, and on virtual methods.
Symbol search (workspace/symbol) queries may be partially qualified. That is, \ 
typing b::Foo will match the symbol a::b::c::Foo.
Refactoring

New refactoring: populate switch statement with cases. (This acts as a fix for \ 
the -Wswitch-enum warning).
Renaming templates is supported, and many other complex cases were fixed.
Attempting to rename to an invalid or conflicting name can produce an error \ 
message rather than broken code. (Not all cases are detected!)
The accuracy of many code actions has been improved.
Hover

Hovers for auto and decltype show the type in the same style as other hovers. \ 
this is also now supported.
Displayed type names are more consistent and idiomatic.
Semantic highlighting

Inactive preprocessor regions (#ifdef) are highlighted as comments.
clangd 12 is the last release with support for the non-standard \ 
textDocument/semanticHighlights notification. Clients sholud migrate to the \ 
textDocument/semanticTokens request added in LSP 3.16.
Remote index (alpha)

clangd can now connect to a remote index server instead of building a project \ 
index locally. This saves resources in large codebases that are slow to index.
The server program is clangd-index-server, and it consumes index files produced \ 
by clangd-indexer.
This feature requires clangd to be built with the CMake flag \ 
-DCLANGD_ENABLE_REMOTE=On, which requires GRPC libraries and is not enabled by \ 
default. Unofficial releases of the remote-index-enabled client and server tools \ 
are at https://github.com/clangd/clangd/releases
Large projects can deploy a shared server, and check in a .clangd file to enable \ 
it (in the Index.External section). We hope to provide such a server for \ 
llvm-project itself in the near future.
Configuration

Static and remote indexes can be configured in the Index.External section. \ 
Different static indexes can now be used for different files. (Obsoletes the \ 
flag --index-file).
Diagnostics can be filtered or suppressed in the Diagnostics section.
Clang-tidy checks can be enabled/disabled in the Diagnostics.ClangTidy section. \ 
(Obsoletes the flag --clang-tidy-checks).
The compilation database directory can be configured in the CompileFlags \ 
section. Different compilation databases can now be specified for different \ 
files. (Obsoletes the flag --compile-commands-dir).
Errors in loaded configuration files are published as LSP diagnostics, and so \ 
should be shown in your editor.
Full reference of configuration options

System integration

Changes to compile_commands.json and compile_flags.txt will take effect the next \ 
time a file is parsed, without restarting clangd.
clangd --check=<filename> can be run on the command-line to simulate \ 
opening a file without actually using an editor. This can be useful to reproduce \ 
crashes or aother problems.
Various fixes to handle filenames correctly (and case-insensitively) on windows.
If incoming LSP messages are malformed, the logs now contain details.
Miscellaneous

“Show AST” request (textDocument/ast) added as an LSP extension. This \ 
displays a simplified view of the clang AST for selected code. The clangd VSCode \ 
extension supports this.
clangd should no longer crash while loading old or corrupt index files.
The flags --index, --recovery-ast and -suggest-missing-includes have been \ 
retired. These features are now always enabled.
Too many stability and correctness fixes to mention.
