Changes to the LLVM IR
|
||||
----------------------
|
||||
|
||||
* The callsite attribute `vector-function-abi-variant
|
||||
<https://llvm.org/docs/LangRef.html#call-site-attributes>`_ has been
|
||||
added to describe the mapping between scalar functions and vector
|
||||
functions, to enable vectorization of call sites. The information
|
||||
provided by the attribute is interfaced via the API provided by the
|
||||
``VFDatabase`` class.
|
||||
|
||||
* `dereferenceable` attributes and metadata on pointers no longer imply
|
||||
anything about the alignment of the pointer in question. Previously, some
|
||||
optimizations would make assumptions based on the type of the pointer. This
|
||||
behavior was undocumented. To preserve optimizations, frontends may need to
|
||||
be updated to generate appropriate `align` attributes and metadata.
|
||||
|
||||
* The DIModule metadata is extended to contain file and line number
|
||||
information. This information is used to represent Fortran modules debug
|
||||
info at IR level.

|
||||
|
||||
During this release ...
|
||||
|
||||
* Implemented C-language intrinsics for the full Arm v8.1-M MVE instruction
|
||||
set. ``<arm_mve.h>`` now supports the complete API defined in the Arm C
|
||||
Language Extensions.
|
||||
|
||||
* Added support for assembly for the optional Custom Datapath Extension (CDE)
|
||||
for Arm M-profile targets.
|
||||
|
||||
* Implemented C-language intrinsics ``<arm_cde.h>`` for the CDE instruction set.
|
||||
|
||||
* Clang now defaults to ``-fomit-frame-pointer`` when targeting non-Android
|
||||
Linux for arm and thumb when optimizations are enabled. Users that were
|
||||
previously not specifying a value and relying on the implicit compiler
|
||||
default may wish to specify ``-fno-omit-frame-pointer`` to get the old
|
||||
behavior. This improves compatibility with GCC.

Changes to the MIPS Target

|
||||
|
||||
During this release ...
|
||||
|
||||
|
||||
* Functions with the probe-stack attribute set to "inline-asm" are now protected
|
||||
against stack clash without the need of a third-party probing function and
|
||||
with limited impact on performance.
|
||||
* -x86-enable-old-knl-abi command line switch has been removed. v32i16/v64i8
|
||||
vectors are always passed in ZMM register when avx512f is enabled and avx512bw
|
||||
is disabled.
|
||||
* Vectors larger than 512 bits with i16 or i8 elements will be passed in
|
||||
multiple ZMM registers when avx512f is enabled. Previously this required
|
||||
avx512bw otherwise they would split into multiple YMM registers. This means
|
||||
vXi16/vXi8 vectors are consistently treated the same as
|
||||
vXi32/vXi64/vXf64/vXf32 vectors of the same total width.
|
||||
|
||||
Changes to the AMDGPU Target
|
||||
-----------------------------
|
||||
|
||||
* The backend default denormal handling mode has been switched to on
|
||||
for all targets for all compute function types. Frontends wishing to
|
||||
retain the old behavior should explicitly request f32 denormal
|
||||
flushing.
|
||||
During this release ...
|
||||
|
||||
Changes to the AVR Target
|
||||
-----------------------------
|
||||
|
||||
* Moved from an experimental backend to an official backend. AVR support is now
|
||||
included by default in all LLVM builds and releases and is available under
|
||||
the "avr-unknown-unknown" target triple.
|
||||
During this release ...
|
||||
|
||||
Changes to the WebAssembly Target
|
||||
---------------------------------
|
||||
|
||||
* Programs which don't have a "main" function, called "reactors" are now
|
||||
properly supported, with a new `-mexec-model=reactor` flag. Programs which
|
||||
previously used `-Wl,--no-entry` to avoid having a main function should
|
||||
switch to this new flag, so that static initialization is properly
|
||||
performed.
|
||||
|
||||
* `__attribute__((visibility("protected")))` now evokes a warning, as
|
||||
WebAssembly does not support "protected" visibility.

Changes to the Debug Info
|
||||
---------------------------------
|
||||
|
||||
* LLVM now supports the debug entry values (DW_OP_entry_value) production for
|
||||
the x86, ARM, and AArch64 targets by default. Other targets can use
|
||||
the utility by using the experimental option ("-debug-entry-values").
|
||||
This is a debug info feature that allows debuggers to recover the value of
|
||||
optimized-out parameters by going up a stack frame and interpreting the values
|
||||
passed to the callee. The feature improves the debugging user experience when
|
||||
debugging optimized code.
|
||||
During this release ...
|
||||
|
||||
Changes to the LLVM tools
|
||||
---------------------------------
|
||||
|
||||
* Added an option (--show-section-sizes) to llvm-dwarfdump to show the sizes
|
||||
of all debug sections within a file.
|
||||
|
||||
* llvm-nm now implements the flag ``--special-syms`` and will filter out special
|
||||
symbols, i.e. mapping symbols on ARM and AArch64, by default. This matches
|
||||
the GNU nm behavior.
