Improvements to clangd
|
||||
----------------------
|
||||
|
||||
- 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``.

||||

New Compiler Flags
|
||||
------------------
|
||||
|
||||
- ...
|
||||
|
||||
- -fpch-codegen and -fpch-debuginfo generate shared code and/or debuginfo
|
||||
for contents of a precompiled header in a separate object file. This object
|
||||
file needs to be linked in, but its contents do not need to be generated
|
||||
for other objects using the precompiled header. This should usually save
|
||||
compile time. If not using clang-cl, the separate object file needs to
|
||||
be created explicitly from the precompiled header.
|
||||
Example of use:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ clang++ -x c++-header header.h -o header.pch -fpch-codegen -fpch-debuginfo
|
||||
$ clang++ -c header.pch -o shared.o
|
||||
$ clang++ -c source.cpp -o source.o -include-pch header.pch
|
||||
$ clang++ -o binary source.o shared.o
|
||||
|
||||
- Using -fpch-instantiate-templates when generating the precompiled header
|
||||
usually increases the amount of code/debuginfo that can be shared.
|
||||
- In some cases, especially when building with optimizations enabled, using
|
||||
-fpch-codegen may generate so much code in the shared object that compiling
|
||||
it may be a net loss in build time.
|
||||
- Since headers may bring in private symbols of other libraries, it may be
|
||||
sometimes necessary to discard unused symbols (such as by adding
|
||||
-Wl,--gc-sections on ELF platforms to the linking command, and possibly
|
||||
adding -fdata-sections -ffunction-sections to the command generating
|
||||
the shared object).
|
||||
- New option ``-fbinutils-version=`` specifies the targeted binutils version.
|
||||
For example, ``-fbinutils-version=2.35`` means compatibility with GNU as/ld
|
||||
before 2.35 is not needed: new features can be used and there is no need to
|
||||
work around old GNU as/ld bugs.
|
||||
|
||||
Deprecated Compiler Flags
|
||||
-------------------------
|
||||
|
||||
The following options are deprecated and ignored. They will be removed in
|
||||
future versions of Clang.
|
||||
|
||||
- ...
|
||||
|
||||
Modified Compiler Flags
|
||||
-----------------------
|
||||
|
||||
- On ELF, ``-gz`` now defaults to ``-gz=zlib`` with the integrated assembler.
|
||||
It produces ``SHF_COMPRESSED`` style compression of debug information. GNU
|
||||
binutils 2.26 or newer, or lld is required to link produced object files. Use
|
||||
``-gz=zlib-gnu`` to get the old behavior.
|
||||
- Now that `this` pointers are tagged with `nonnull` and `dereferenceable(N)`,
|
||||
`-fno-delete-null-pointer-checks` has gained the power to remove the
|
||||
`nonnull` attribute on `this` for configurations that need it to be nullable.
|
||||
- ``-gsplit-dwarf`` no longer implies ``-g2``.
|
||||
- ``-fasynchronous-unwind-tables`` is now the default on Linux AArch64/PowerPC.
|
||||
This behavior matches newer GCC.

What's New in Libc++ 12.0.0?
|
||||
What's New in Libc++ 13.0.0?
|
||||
============================
|
||||
|
||||
New Features
|
||||
------------
|
||||
- Random device support has been made optional. It's enabled by default and can
|
||||
be disabled by building libc++ with ``-DLIBCXX_ENABLE_RANDOM_DEVICE=OFF``.
|
||||
Disabling random device support can be useful when building the library for
|
||||
platforms that don't have a source of randomness, such as some embedded
|
||||
platforms. When this is not supported, most of ``<random>`` will still be
|
||||
available, but ``std::random_device`` will not.
|
||||
- Localization support has been made optional. It's enabled by default and can
|
||||
be disabled by building libc++ with ``-DLIBCXX_ENABLE_LOCALIZATION=OFF``.
|
||||
Disabling localization can be useful when porting to platforms that don't
|
||||
support the C locale API (e.g. embedded). When localization is not
|
||||
supported, several parts of the library will be disabled: ``<iostream>``,
|
||||
``<regex>``, ``<locale>`` will be completely unusable, and other parts may be
|
||||
only partly available.
|
||||
- If libc++ is compiled with a C++20 capable compiler it will be compiled in
|
||||
C++20 mode. Else libc++ will be compiled in C++17 mode.
|
||||
- Several unqualified lookups in libc++ have been changed to qualified lookups.
|
||||
This makes libc++ more ADL-proof.
|
||||
- The libc++ implementation status pages have been overhauled. Like other parts
|
||||
documentation they now use restructured text instead of html. Starting with
|
||||
libc++12 the status pages are part of libc++'s documentation.
|
||||
- More C++20 features have been implemented. :doc:`Cxx2aStatus` has the full
|
||||
overview of libc++'s C++20 implementation status.
|
||||
- Work has started to implement new C++2b features. :doc:`Cxx2bStatus` has the
|
||||
full overview of libc++'s C++2b implementation status.
|
||||
|
||||
- ...
|
||||
|
||||
API Changes
|
||||
-----------
|
||||
- By default, libc++ will _not_ include the definition for new and delete,
|
||||
since those are provided in libc++abi. Vendors wishing to provide new and
|
||||
delete in libc++ can build the library with ``-DLIBCXX_ENABLE_NEW_DELETE_DEFINITIONS=ON``
|
||||
to get back the old behavior. This was done to avoid providing new and delete
|
||||
in both libc++ and libc++abi, which is technically an ODR violation. Also
|
||||
note that we couldn't decide to put the operators in libc++ only, because
|
||||
they are needed from libc++abi (which would create a circular dependency).
|
||||
- During the C++20 standardization process some new low-level bit functions
|
||||
have been renamed. Libc++ has renamed these functions to match the C++20
|
||||
Standard.
|
||||
- ``ispow2`` has been renamed to ``has_single_bit``
|
||||
- ``ceil2`` has been renamed to ``bit_ceil``
|
||||
- ``floor2`` has been renamed to ``bit_floor``
|
||||
- ``log2p1`` has been renamed to ``bit_width``
|
||||
|
||||
- In C++20 mode, ``std::filesystem::path::u8string()`` and
|
||||
``generic_u8string()`` now return ``std::u8string`` according to P0428,
|
||||
while they return ``std::string`` in C++17. This can cause source
|
||||
incompatibility, which is discussed and acknowledged in P1423, but that
|
||||
paper doesn't suggest any remediation for this incompatibility.

Changes to building LLVM
|

------------------------
|
||||
|
||||
* The internal ``llvm-build`` Python script and the associated ``LLVMBuild.txt``
|
||||
files used to describe the LLVM component structure have been removed and
|
||||
replaced by a pure ``CMake`` approach, where each component stores extra
|
||||
properties in the created targets. These properties are processed once all
|
||||
components are defined to resolve library dependencies and produce the header
|
||||
expected by llvm-config.
|
||||

||||
Changes to TableGen
|
||||
-------------------
|
||||
|
||||
* The new "TableGen Programmer's Reference" replaces the "TableGen Language
|
||||
Introduction" and "TableGen Language Reference" documents.
|
||||
|
||||
* The syntax for specifying an integer range in a range list has changed.
|
||||
The old syntax used a hyphen in the range (e.g., ``{0-9}``). The new syntax
|
||||
uses the "`...`" range punctuation (e.g., ``{0...9}``). The hyphen syntax
|
||||
is deprecated.

During this release ...
|
||||
|
||||
* The 'mpx' feature was removed from the backend. It had been removed from clang
|
||||
frontend in 10.0. Mention of the 'mpx' feature in an IR file will print a
|
||||
message to stderr, but IR should still compile.
|
||||
* Support for ``-march=alderlake``, ``-march=sapphirerapids``,
|
||||
``-march=znver3`` and ``-march=x86-64-v[234]`` has been added.
|
||||
* The assembler now has support for {disp32} and {disp8} pseudo prefixes for
|
||||
controlling displacement size for memory operands and jump displacements. The
|
||||
assembler also supports the .d32 and .d8 mnemonic suffixes to do the same.
|
||||
* A new function attribute "tune-cpu" has been added to support -mtune like gcc.
|
||||
This allows microarchitectural optimizations to be applied independent from
|
||||
the "target-cpu" attribute or TargetMachine CPU which will be used to select
|
||||
Instruction Set. If the attribute is not present, the tune CPU will follow
|
||||
the target CPU.
|
||||
* Support for ``HRESET`` instructions has been added.
|

* Support for ``UINTR`` instructions has been added.

Changes to the LLVM tools
|
||||
---------------------------------
|
||||
|
||||
* llvm-readobj and llvm-readelf behavior has changed to report an error when
|
||||
executed with no input files instead of reading an input from stdin.
|
||||
Reading from stdin can still be achieved by specifying `-` as an input file.
|
||||
|
||||
* llvm-mca supports serialization of the timeline and summary views.
|

The `--json` command line option prints a JSON representation of
|

these views to stdout.

|
||||
Changes to Sanitizers
|
||||
---------------------
|
||||
|
||||
The integer sanitizer `-fsanitize=integer` now has a new sanitizer:
|
||||
`-fsanitize=unsigned-shift-base`. It's not undefined behavior for an unsigned
|
||||
left shift to overflow (i.e. to shift bits out), but it has been the source of
|
||||
bugs and exploits in certain codebases in the past.
|
||||
|
||||
Many Sanitizers (asan, cfi, lsan, msan, tsan, ubsan) have support for

||||
musl-based Linux distributions. Some of them may be rudimentary.
