Due to the known limitations of .set reassignment (see
https://sourceware.org/PR288), we use diagnostics to reject patterns
that could lead to errors (ae7ac010594f693fdf7b3ab879e196428d961e75 2009-06)).
This code gets refined multiple times, see:
* 9b4a824217f1fe23f83045afe7521acb791bc2d0 (2010-05) `IsUsedInExpr`
* 46c79ef1132607aead144dfda0f26aa8b065214f (2010-11) renamed `IsUsedInExpr` to `IsUsed`
The related `SetUsed` bit seems unnecessary nowadays.
This reverts commit 68ab45f0533f3bbfc1c96bddd53de7e769180219, reapplying
2fd860c1f559c0b0be66cc000e38270a04d0a1a3. The only change is keeping
"lldb/Host/Config.h", which I believe was the cause of the failures.
Some test files for flat container adaptors redundantly include
`<iostream>` and, surprisingly, `<cstddef>`. This patch removes the
redundant inclusions.
Inclusions of `<vector>` is also removed since a sane implementation is
expected to make instantiation of `flat_(multi)map<K, V>` or
`flat_(multi)set<K>` valid when only `<flat_map>` or `<flat_set>` is
included.
Reverts llvm/llvm-project#135429 due buildbot breakage:

Based on the ASan output, I think after the replaceOp on line 775, it's
no longer valid to do getSize() on sliceOp:
```
775 rewriter.replaceOp(sliceOp, newSliceOp.getResult());
776
777 // Remove const_shape size op when it no longer has use point.
778 Operation *sizeConstShape = sliceOp.getSize().getDefiningOp();
```
Move `Fixup.getKind() >= FirstLiteralRelocationKind` from target hooks
to ELFObjectWriter::recordRelocation.
Currently, getRelocType cannot be skipped for LoongArch due to #135519
Add `AllowedTypes` options to support custom defined char like type.
treat `unsigned char` and `signed char` as char like type by default.
The allowed types only effect when the var decl or explicit cast to this
non-canonical type names.
Fixed: #133425
The function is called to test the fast path - when Lo/Hi are within the
same fragment. This is unsafe - Lo/Hi at the begin and end of a
relaxable fragment should not evaluate to a constant. However, we don't
have tests that exercise the code path.
Nevertheless, make the check safer and remove the now unnecessary
isRISCV check (from https://reviews.llvm.org/D103539).
The `__log2i` function template in `<algorithm/sort.h>` is basically
equivalent to `__bit_log2` in `<__bit/bit_log2.h>`. It seems better to
avoid duplication.
On one hand, we intend to force import all functions when the option is
enabled.
On the other hand, we currently drop definitions of some functions and
convert
them to declarations, which contradicts this intent.
With this PR, functions will no longer be converted to declarations when
`force-import-all` is enabled.
The MCOperandPredicate seems to allow symbols as well as immediates, but
the parser/matcher does not due to `isCLUIImm`. This brings both in line
with each other, and should prevent trying to compress a `lui` with a
symbol, which cannot be emitted as a `c.lui` as there are no relocations
for this as `R_RISCV_RVC_LUI` is deprecated/removed.
MaxVF computed in couldPreventStoreLoadFowrard may not be a power of 2,
as CommonStride may not be a power-of-2.
This can cause crashes after 78777a20. Use bit_floor to make sure it is
a suitable power-of-2.

Issue #59813 mentions that static members are not included in
the documentation generated by clang-doc. This patch adds
some basic testing for that property, with the current incorrect
behavior. Follow up patches will address the missing documentation.
This relands https://github.com/llvm/llvm-project/pull/135119, after
fixing crashes seen in LLDB CI reported here:

This changes the TemplateArgument representation to hold a flag
indicating whether a tempalte argument of expression type is supposed to
be canonical or not.
This gets one step closer to solving
https://github.com/llvm/llvm-project/issues/92292
This still doesn't try to unique as-written TSTs. While this would
increase the amount of memory savings and make code dealing with the AST
more well-behaved, profiling template argument lists is still too
expensive for this to be worthwhile, at least for now.
This also fixes the context creation of TSTs, so that they don't in some
cases get incorrectly flagged as sugar over their own canonical form.
This is captured in the test expectation change of some AST dumps.
This fixes some places which were unnecessarily canonicalizing these
TSTs.
The code was using the number of source operands plus one. The plus one
seems to be an ARM specific value accounting for one of the source
operands having 2 sub operands. No other target in tree uses
PseudoLowering with variadic instructions so this worked.
This patch replaces it with a proper count of the number of sub operands
of all operands. While there I update the loop to use MIOperandNo so we
don't need to count up the sub operands as we go.
This reverts commit 54e70ac7650f1c22f687937d1a082e4152f97b22 which
itself fixed an [asan
leak](https://lab.llvm.org/buildbot/#/builders/55/builds/9761) from the
original upstreaming commit. The leak was due to op allocations not
being `free`ed.
~~The necessary change was to explicitly `->destroy()` the ops at the
end of the tests. I believe this is because the rewriter used in the
tests doesn't actually insert them into a module and so without an
explicit `->destroy()` no bookkeeping process is able to take care of
them.~~
The necessary change was to use `OwningOpRef` which calls `op->erase()`
in its [own
destructor](89cfae41ec/mlir/include/mlir/IR/OwningOpRef.h (L39)).
Copies the not-yet-implemented items planned for removal from the
LLVM-20 to the LLVM-21 release notes. This allows to better keep track
of the status of the next release.
Adjusting the existing script to match the new output makes it easy to
review the new script works correctly.
This adjusts the tests to match the changes in the new tests, Notably
- removes the synopsis uses 2 spaces indent in `# if`
It does not implement the conditional include part. This would be quite
some effort and these diffs are easy to review manually.
Note there are no tests for the changes; the existing script will be
phased out when the next generators are complete.
This patch adds `nocallback` attributes for string/math libcalls. It
allows FuncAttributor to infer `norecurse` more precisely and encourages
more aggressive global optimization.
