[llvm] Remove the docs for the (now removed) LLVM test-suite Makefiles (#179288)
The LLVM test suite used to provide a Makefile-based suite, which had
been deprecated and mostly unmaintained for many years. As explained in
https://discourse.llvm.org/t/llvm-test-suite-removing-the-deprecated-makefiles,
we recently got consensus to remove that test suite, which was done in
llvm/llvm-test-suite#320. This patch cleans up the related
documentation.
[libc++] Enable additional tests when Clang modules are enabled (#168967)
Disabling tests when Clang modules are enabled is not great because we
are moving more and more tests towards using Clang modules by default.
Instead, disable Clang modules on a per-test basis.
[HLSL][DXIL][SPRIV] Added WaveActiveProduct intrinsic #164385 (#165109)
From issue #99165, adds the implementation of WaveActiveProduct. Mainly
followed how WaveActiveSum was implemented
- [x] Implement WaveActiveProduct clang builtin,
- [x] Link WaveActiveProduct clang builtin with hlsl_intrinsics.h
- [x] Add sema checks for WaveActiveProduct to
CheckHLSLBuiltinFunctionCall in SemaChecking.cpp
- [x] Add codegen for WaveActiveProduct to EmitHLSLBuiltinExpr in
CGBuiltin.cpp
- [x] Add codegen tests to
clang/test/CodeGenHLSL/builtins/WaveActiveProduct.hlsl
- [x] Add sema tests to
clang/test/SemaHLSL/BuiltIns/WaveActiveProduct-errors.hlsl
- [x] Create the int_dx_WaveActiveProduct intrinsic in
IntrinsicsDirectX.td
- [x] Create the DXILOpMapping of int_dx_WaveActiveProduct to 119 in
DXIL.td

[SPARC] Set how many bytes load from or store to stack slot (#182674)
Refer from: https://reviews.llvm.org/D44782
The testcase is copied from
llvm/test/CodeGen/RISCV/stack-slot-coloring.mir.
[MLIR][Python] Allow passing dialect as a class keyword argument (#182465)
Previously, we constructed new ops using the pattern `class
MyOp(MyInt.Operation)`.
Now we’ve added a new pattern: `class MyOp(Operation, dialect=MyInt)`,
which allows more flexible composition. For example:
```python
class BinOpBase(Operation): # it can be used in any dialect!
res: Result[Any]
lhs: Operand[Any]
rhs: Operand[Any]
class MyInt(Dialect, name="myint"):
pass
class AddOp(BinOpBase, dialect=MyInt, name="add"):
...
```
[TableGen] Add OPC_EmitIntegerByHwMode0 and OPC_CheckChildXTypeByHwMode0. NFC (#182686)
Add versions of these opcodes that implicitly call getValueTypeForHwMode
with index 0.
This reduces llc size by ~100K.
[clang][diagnostics] Refactor `warn_doc_function_method_decl_mismatch` to use enum_select (#181769)
Related: https://github.com/llvm/llvm-project/issues/123121
This patch refactors the `warn_doc_function_method_decl_mismatch`
diagnostic to use `enum_select` instead of `select`. This gets rid of
magic numbers in its caller and improves readability.
[LLVM][ADT] Add some more `starts_with`, `ends_with`, and `contains` overloads to `SmallString` (#182692)
This makes `SmallString` consistent with `std::string`,
`std::string_view`, and `StringRef`.
[ELF] Add target-specific relocation scanning for ARM (#182440)
Implement ARM::scanSectionImpl, following the pattern established for
AArch64 and other targets. This merges the getRelExpr and TLS handling
for SHF_ALLOC sections into the target-specific scanner, enabling
devirtualization and eliminating abstraction overhead.
- Inline relocation classification into scanSectionImpl with a switch
on relocation type, replacing the generic rs.scan() path.
- Use processR_PC/processR_PLT_PC for common PC-relative and PLT
relocations.
- Handle TLS inline: checkTlsLe for TLS LE, handleTlsIe<false> for
TLS IE (no IE-to-LE optimization for ARM), and direct flag/reloc
emission for TLS GD/LD (no GD/LD optimization for ARM).
- Set hasGotOffRel for R_GOTREL/R_GOTONLY_PC relocations.
- Simplify getRelExpr to only handle relocations needed by
relocateNonAlloc and preprocessRelocs.
[flang][NFC] Converted five tests from old lowering to new lowering (part 19) (#182554)
Tests converted from test/Lower/forall: forall-construct-4.f90,
forall-construct.f90, forall-ranked.f90, forall-slice.f90,
forall-stmt.f90
[lldb][Process/FreeBSDKernel] Print unread message buffer on start (#178027)
This is equivalent of kgdb_dmesg() in fbsd-kvm.c in FreeBSD kgdb(1)
port. Unread kernel messages is only printed in interactive mode (i.e.
not in batch mode) to mimic KGDB's behaviour.
Example output:
```
➜ sudo ./build/bin/lldb /boot/kernel/kernel -c /var/crash/vmcore.last
(lldb) target create "/boot/kernel/kernel" --core "/var/crash/vmcore.last"
Unread portion of the kernel message buffer:
panic: kdb_sysctl_panic
cpuid = 1
time = 1769364579
KDB: stack backtrace:
db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe01b435fa20
vpanic() at vpanic+0x136/frame 0xfffffe01b435fb50
panic() at panic+0x43/frame 0xfffffe01b435fbb0

[llvm-mca][Darwin] Fix crash on .subsections_via_symbols in asm input (#182694)
## Summary
This PR fixes an llvm-mca crash on Darwin assembly containing
`.subsections_via_symbols`. The directive is forwarded by
`DarwinAsmParser` to `emitSubsectionsViaSymbols()`, which crashes when
it hits the base `MCStreamer` `llvm_unreachable` path. The fix adds a
no-op override in `llvm/tools/llvm-mca/CodeRegionGenerator.h`, scoped to
llvm-mca only
## Problem manifestation
I ran across this while tinkering around with making an interactive
interpreter/code analyzer and implementing apple silicon support.
## Root cause
- `DarwinAsmParser::parseDirectiveSubsectionsViaSymbols` calls

[SelectionDAG] Emit error instead of asserting for unsupported FP_EXTEND (#182660)
Replace the assertion failure in
`DAGTypeLegalizer::SoftenFloatRes_FP_EXTEND` with a user-friendly error
when no libcall is available for the requested
Fix
Replace the `assert` with an `emitError` call that reports the
unsupported
conversion gracefully and returns a poison value
Fixes: #182449
