TargetLowering: Allow FMINNUM/FMAXNUM to lower to FMINIMUM/FMAXIMUM even without `nsz` (#177828)
This restriction was originally added in
https://reviews.llvm.org/D143256, with the given justification:
> Currently, in TargetLowering, if the target does not support fminnum,
we lower to fminimum if neither operand could be a NaN. But this isn't
quite correct because fminnum and fminimum treat +/-0 differently; so,
we need to prove that one of the operands isn't a zero.
As far as I can tell, this was never correct. Before
https://github.com/llvm/llvm-project/pull/172012, `minnum` and `maxnum`
were nondeterministic with regards to signed zero, so it's always been
perfectly legal to lower them to operations that order signed zeroes.
py-pillow_heif: update to 1.2.0.
## [1.2.0 - 2026-01-23]
### Changed
- libheif was updated from the `1.20.2` to `1.21.2` version. #399
- Dropped `Python 3.9` support. #402
- `PREFERRED_DECODER` must now always be a valid, available decoder ID, or an exception will be raised. (libheif change)
### Fixed
- PREFERRED_DECODER is now correctly taken into account when decoding depth and aux images. #399
py-markdown: update to 3.10.1.
Fixed
Ensure nested elements inside inline comments are properly unescaped (#1571).
Make the docs build successfully with mkdocstrings-python 2.0 (#1575).
Fix infinite loop when multiple bogus or unclosed HTML comments appear in input (#1578).
Fix another infinite loop when handling bad comments (#1586).
py-cparser: update to 3.0.
Removed dependency on PLY, by rewriting pycparser to use a hand-written lexer and recursive-descent parser for C. No API changes / functionality changes intended - the same AST is produced.
Add support for Python 3.14 and drop EOL 3.8 by @hugovk in #581
Update _ast_gen.py to be in sync with c_ast.py by @simonlindholm in #582
[LV] Add additional tests for early-exit loops loads not known deref.
Add additional test coverage for loops with loads that are not known to
be dereferenceable.
py-black: update to 26.1.0.
## 26.1.0
### Highlights
Introduces the 2026 stable style (#4892), stabilizing the following changes:
- `always_one_newline_after_import`: Always force one blank line after import
statements, except when the line after the import is a comment or an import statement
(#4489)
- `fix_fmt_skip_in_one_liners`: Fix `# fmt: skip` behavior on one-liner declarations,
such as `def foo(): return "mock" # fmt: skip`, where previously the declaration would
have been incorrectly collapsed (#4800)
- `fix_module_docstring_detection`: Fix module docstrings being treated as normal
strings if preceded by comments (#4764)
- `fix_type_expansion_split`: Fix type expansions split in generic functions (#4777)
- `multiline_string_handling`: Make expressions involving multiline strings more compact
(#1879)

[InstCombine] Don't convert a compare+select into a minnum/maxnum intrinsic that can't be lowered back to a compare+select (#177821)
This is a step on the yak-shaving expedition to properly implement the
new `minnum`/`maxnum` signed-zero semantics.
`InstCombineSelect` will convert a `fcmp`+`select` sequence to a
`minnum`/`maxnum` intrinsic. It doesn't require the `fcmp` to have any
particular fast-math flags, just that the `select` has `nnan` and `nsz`
(or is being used in a context where the result doesn't care about
signed zero).
It's not correct to propagate the `nnan` flag from the `fcmp`
instruction for poison-propagation reasons. Patches like
https://github.com/llvm/llvm-project/pull/117977 and
https://github.com/llvm/llvm-project/pull/141010 have *generously* made
it so that if `fcmp` doesn't have fast-math flags, we can still perform
the transformation by simply dropping the flags on the generated
intrinsic.
