Revert "[mlir] Link libraries that aren't included in libMLIR to libMLIR (#123477)"
This reverts commit af6616676fb7f9dd4898290ea684ee0c90f1701d. It broke
builds with `-DBUILD_SHARED_LIBS=ON`.
[SystemZ] Add support for new cpu architecture - arch15
This patch adds support for the next-generation arch15
CPU architecture to the SystemZ backend.
This includes:
- Basic support for the new processor and its features.
- Detection of arch15 as host processor.
- Assembler/disassembler support for new instructions.
- Exploitation of new instructions for code generation.
- New vector (signed|unsigned|bool) __int128 data types.
- New LLVM intrinsics for certain new instructions.
- Support for low-level builtins mapped to new LLVM intrinsics.
- New high-level intrinsics in vecintrin.h.
- Indicate support by defining __VEC__ == 10305.
Note: No currently available Z system supports the arch15
architecture. Once new systems become available, the
official system name will be added as supported -march name.
[clang] Improve the documentation for the init_priority attribute (#123098)
The documentation wasn't very clear about whether ordering is controlled
within or across TUs, and same for dylibs. Clarify that, and also add
mentions for the state of support on Mach-O platforms.
[memprof] Add simplify_type (NFC) (#123556)
IndexCall is a simple wrapper around:
PointerUnion<CallsiteInfo *, AllocInfo *>
Now, because we don't have CastInfo for IndexCall, we would have to
use getBase like so:
dyn_cast_if_present<CallsiteInfo *>(Call.getBase())
This patch adds simplify_type<IndexCall>, which in turn enables
CastInfo for IndexCall, so we can drop getBase like so::
dyn_cast_if_present<CallsiteInfo *>(Call)
[libc++][chrono] implements UTC clock.
While implementing this feature and its associated LWG issues it turns out
- LWG3316 Correctly define epoch for utc_clock / utc_timepoint
only added non-normative wording to the standard.
Implements parts of:
- P0355 Extending <chrono> to Calendars and Time Zones
- P1361 Integration of chrono with text formatting
- LWG3359 <chrono> leap second support should allow for negative leap seconds
[AMDGPU] Handle natively unsupported types in addrspace(7) lowering (#110572)
The current lowering for ptr addrspace(7) assumed that the instruction
selector can handle arbtrary LLVM types, which is not the case. Code
generation can't deal with
- Values that aren't 8, 16, 32, 64, 96, or 128 bits long
- Aggregates (this commit only handles arrays of scalars, more may come)
- Vectors of more than one byte
- 3-word values that aren't a vector of 3 32-bit values (for axample, a
<6 x half>)
This commit adds a buffer contents type legalizer that adds the needed
bitcasts, zero-extensions, and splits into subcompnents needed to
convert a load or store operation into one that can be successfully
lowered through code generation.
In the long run, some of the involved bitcasts (though potentially not
the buffer operation splitting) ought to be handled by the instruction
legalizer, but SelectionDAG makes this difficult.

[NFC] llvm-cgdata use StringRef in exitWithError to reduce construction (#120771)
Replace `static void exitWithError(Twine Message, std::string Whence =
"", std::string Hint = "")` std::string with StringRef to remove
constructing Strings on every call or passing by value
Fixes: #100065
[mlir] Link libraries that aren't included in libMLIR to libMLIR (#123477)
Use `mlir_target_link_libraries()` to link dependencies of libraries
that are not included in libMLIR, to ensure that they link to the dylib
when they are used in Flang. Otherwise, they implicitly pull in all
their static dependencies, effectively causing Flang binaries to
simultaneously link to the dylib and to static libraries, which is never
a good idea.
I have only covered the libraries that are used by Flang. If you wish, I
can extend this approach to all non-libMLIR libraries in MLIR, making
MLIR itself also link to the dylib consistently.
[SPIR-V] Fix SPIRVEmitIntrinsics undefined behavior (#123625)
Before this change InstrSet in SPIRVEmitIntrinsics was uninitialized
before running runOnFunction. This change adds a new function
getPreferredInstructionSet in SPIRVSubtarget.
[ConstantFolding] Add ilogb in isMathLibCallNoop (#122582)
ilogb libcall was not being constant folded correctly. This patch adds
ilogb case in isMathLibCallNoop with correct error condition.
Fixes #101873
[SDAG] Fix CSE for ADDRSPACECAST nodes (#122912)
Correct CSE in SelectionDAG can make DAG combining more effective and
reduces the size of the DAG and thus should improve compile time.
[libc++] Define an internal API for std::invoke and friends (#116637)
Currently we're using quite different internal names for the
`std::invoke` family of type traits. This adds a layer around the
current implementation to make it easier to understand when it is used
and makes it easier to define multiple implementations of it.
Add missing include to X86MCTargetDesc.h (#123320)
In gcc-15, explicit includes of `<cstdint>` are required when fixed-size
integers are used. In this file, this include only happened as a side
effect of including SmallVector.h
Although llvm compiles fine, the root-project would benefit from
explicitly including it here, so we can backport the patch.
Maybe interesting for @hahnjo and @vgvassilev
[AMDGPU] Fix DAG types for V_MAD_I64_I32 and V_MAD_U64_U32. NFC. (#123629)
These instructions return a 64-bit result and a 1-bit carry, unlike
smul_lohi and umul_lohi which return a pair of 32-bit results.
This does not appear to make any difference in practice because the DAG
types are not used for anything before these nodes are converted to
MachineInstrs.
[libclc] Move mad to the CLC library (#123607)
All targets build `__clc_mad` -- even SPIR-V targets -- since it
compiles to the optimal `llvm.fmuladd` intrinsic. There is no change to
the bytecode generated for non-SPIR-V targets.
The `mix` builtin, which is implemented as a wrapper around `mad`, is
left as an OpenCL-layer wrapper of `__clc_mad`. I don't know if it's
worth having a specific CLC version of `mix`.
The changes to the other CLC files/functions are moving uses of `mad` to
`__clc_mad`, and reformatting. There is an additional instance of
`trunc` becoming `__clc_trunc`, which was missed before.
[BOLT] Skip flushing optional out-of-range pending relocs
When a pending relocation is created it is also marked whether it is
optional or not. It can be optional when such relocation is added as
part of an optimization (i.e., `scanExternalRefs`).
When bolt tries to `flushPendingRelocations`, it safely skips any
optional relocations that cannot be encoded.
Background:
BOLT, as part of scanExternalRefs, identifies external references from
calls and creates some pending relocations for them. Those when flushed
will update references to point to the optimized functions. This
optimization can be disabled using `--no-scan`.
BOLT can assert if any of these pending relocations cannot be encoded.
This patch does not disable this optimization but instead selectively
applies it given that a pending relocation is optional.
