|
||||
|
||||
* ...
|
||||
|
||||
* Added the ``byref`` attribute to better represent argument passing
|
||||
for the `amdgpu_kernel` calling convention.
|
||||
|
||||
* Added type parameter to the ``sret`` attribute to continue work on
|
||||
removing pointer element types.
|
||||
|
||||
* The ``llvm.experimental.vector.reduce`` family of intrinsics have been renamed
|
||||
to drop the "experimental" from the name, reflecting their now fully supported
|
||||
status in the IR.
|
||||
|
||||
|
||||
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.

||||

||||
Changes to the ARM Backend

@ -113,31 +85,11 @@ Changes to the X86 Target
|
||||
|
||||
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.
|
||||
* Support for ``AVXVNNI`` instructions has been added.
|
||||
|
||||
Changes to the AMDGPU Target
|
||||
-----------------------------
|
||||
|
||||
During this release ...
|
||||
|
||||
* The new ``byref`` attribute is now the preferred method for
|
||||
representing aggregate kernel arguments.

Changes to the AVR Target

@ -169,38 +121,16 @@ Changes to the Debug Info
|
||||
|
||||
During this release ...
|
||||
|
||||
* The DIModule metadata is extended with a field to indicate if it is a
|
||||
module declaration. This extension enables the emission of debug info
|
||||
for a Fortran 'use <external module>' statement. For more information
|
||||
on what the debug info entries should look like and how the debugger
|
||||
can use them, please see test/DebugInfo/X86/dimodule-external-fortran.ll.
|
||||
|
||||
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 LLDB
|
||||
---------------------------------
|
||||
|
||||
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.
