[mlir][arith] Check overflow when reassociating integer constants
Folding (x + 100 nsw) + 100 nsw to x + (-56) nsw in i8 introduces
poison for inputs such as x = -100 that were previously defined.
Check signed and unsigned overflow when folding constants in the
add/sub/mul reassociation patterns. Retain each common nsw/nuw flag
only when its constant arithmetic does not overflow. Keep index
behavior unchanged for a separate fix.
Add regression coverage for invalid and preserved overflow flags.
Eliminate very low concurrency limit in RAIDframe, improving write throughput as much as 25%.
RAIDframe maintains a per-set freelist of "emergency buffers" to ensure it can perform I/O
under heavy memory pressure. The freelist size was 10, and each I/O request can require
up to 2 buffers in some recovery conditions, so raidPtr->openings was limited to RAIDOUTSTANDING,
which was set to 6 (this was a bug; it should have been 5).
There is no need at all for this limit for RAID 0 or RAID 1 sets; they do not buffer I/O in
the relevant way. Eliminate the allocation entirely in this case; openings is set as the
configured queue length for the RAID set.
For parity RAID sets, we dynamically size two freelists of pre-allocated buffers and the
openings value so that we consume no more than 1% of system RAM per set:
openings = MIN(maxQueueDepth, MAX(RAIDOUTSTANDING, (1% of physmem), bytes_per_opening))
stripe buffers: 2 * openings
I/O buffers: openings * max_stripes_per_bp * numCol
RAIDOUTSTANDING (now used as a floor) remains 6.

mailsend-go: update to 1.0.13
* Fix Issue #76. The options -printCerts and -verifyCert now take effect
while sending mail, not just with -info. Added -verbose as a shortcut for
-debug -printCerts -verifyCert together.
No need to update unless you need certificate details or verification while sending mail.
* Some code cleanup, use go 1.27 to compile, tagged quotedprintable to
v1.0.1. Updated gomail v1.0.4 to use quotedprintable v1.0.1.
www/node2{2,4,6}: Use bundled merve to avoid loading two simdutfs
node dies with SIGBUS (signal 10) the first time it lexes the exports
of a CommonJS module, e.g. early in any `npm install`, for example
www/tailwindcss4 fails to build, reporting "*** Signal 10".
Running lldb inside poudriere build, because we get a core dump:
frame #0 libsimdutf.so.36 simdutf::detail::find(...) +77: jmpq *%rax
frame #1 libmerve.so.1 lexer::CJSLexer::addReexport(...)
...
frame #6 node node::cjs_lexer::Parse(...)
rax = 0x4444444443434343 ("CCCCDDDD", string data)
This appears to be caused by having two different simdutf versions
loaded into one process:
- node is configured with --shared-merve but not --shared-simdutf, so

cnmagic(9): minor tweaks
Call it a "magic sequence" (not "magic key sequence") - there are no
"keys" in the serial input and wscons(4) does not even use cnmagic(9),
so. Mention that latter fact in CAVEATS.
Document CNC_BREAK.
Update to 9.50
Upstream changes:
9.50 2026-10-16
- Added SECURITY.md policy for reporting security issues.
- Fixed a security issue in Mojo::DOM where the content of title and textarea elements was not escaped during
rendering, allowing escaped end tags to break out and turn sanitized HTML into live markup.
9.49 2026-08-10
- Added EXPERIMENTAL support for partitioned cookies. (rawleyfowler)
- Added EXPERIMENTAL partitioned attributes to Mojo::Cookie::Response and Mojolicious::Sessions
devel/libagcre and textproc/agcre: Update to version 20261015
Changes since previous version:
Bring over changes from the development branch:
+ unicode escapes can be set with \xNNNN as well as \uNNNN
+ tighten up bounds checking when looking ahead while compiling
+ make sure illegal utf8 sequences are handled as single bytes
+ fill out the unicode sequences recognised by unicode_isprint
and unicode_isgraph
+ update unicode_isspace to not recognise 0x200e and 0x200f (they're
directional markers for BiDi text, not whitespace)
+ tighten up the way hex numbers are calculated in unicode escapes
+ bump version number to 20261015
Fix remaining condition identity collisions and mismatches
Follow up on #233038 by preserving Clang's substituted template bindings
when normalizing condition roots. Profile written array bounds through
TypeLoc, including typedef definitions and adjusted function parameters.
Retain bindings in function types and qualified member references, and
include template-specialization qualifiers and array-trait dimensions.
Use the same type normalization for qualified references and aliases.
Normalize Flang intrinsic declarations and implied-DO indices independently
of their scope-local symbol addresses. Preserve resolved procedure identity
and distinguish implied-DO bindings by nesting and type, allowing identical
conditions to participate in the strict-subset tie-break again.
Correct the Clang runtime symbol checks and declare-variant candidate
order. Exercise fresh matching after PCH loading, and add paired distinct
and identical expression controls. Update the implicit-NOTHING test to
check its guarded selection and barrier fallback under source-selector
subset comparison.

[LV] Check stores to invariant addresses before handling unsafe deps (#233142)
canVectorizeMemory validates stores to loop-invariant addresses only
after handling the case where LAA reports the loop as unsafe. The early
exit checking canVectorizeIndirectUnsafeDependences account for
histograms skipped the invariant address checks.
Reorder checks to make sure such accesses are checked even if there
histograms to fix miscompile.

[OpenMP] Preserve condition identity in subset ties (partial #233038)
Subset comparisons previously treated unrelated user conditions with the
same applicability trait as equal. This could select the wrong directive
when candidate scores tied. Add frontend-produced condition keys and
compare source selectors separately from their effective ranking traits.
The standalone Flang reproducer in #233038 now tests a before b and selects
TASKYIELD when both are true. The shared matcher retains the expected
strict-superset result for identical conditions and preserves precedence
when the first candidate has a higher score. This is a partial fix: known
identity defects and failing regression tests remain.
Implemented:
- Add owned condition keys and optional immutable original-selector
snapshots to VariantMatchInfo. Normalize condition truth bits only for
subset comparison, count condition presence once, and require matching
known keys when a prospective subset contains a condition. Keep the
