www/hedgedoc: Add new port
The best platform to write and share markdown.
HedgeDoc (formerly known as CodiMD) is an open-source, web-based,
self-hosted, collaborative markdown editor.
You can use it to easily collaborate on notes, graphs and even
presentations in real-time. All you need to do is to share your
note-link to your co-workers and they're ready to go.
...
This brings back www/hedgedoc which was removed a while back because of
the node.js version on tree.
[ConstraintElim] Fold sadd.with.overflow with a constant op. (#223239)
Generalize the overflow-math simplification to also allow simplifying
sadd.with.overflow if the second operand is constant, using
makeGuaranteedNoWrapRegion.
Note that this partially overlaps with the flag strengthening logic.
I'll share a patch soon to try to unify the code more.
No improvements in llvm-opt-benchmarks-nightly. It improves end-to-end
optimizations for Swift (which emits a lot of checked arithmetic) and
also Clang + UBsan.
An end-to-end improvement with overflow intrinsics is

RegisterCoalescer: Remove empty subranges after merging subranges (#222050)
Merging subranges in joinVirtRegs didn't try to clear empty ranges after
refineSubRanges, manifesting in an assert in overlaps checks later.
Exposed with subregister liveness once LiveIntervals runs before
TwoAddress.

smptd: extend mask-src to suppress session details
mask-src omits the source host from Received headers but retains the
SMTP variant, TLS parameters and authentication details; suppress the
with clause and TLS metadata, including the authentication status and
username emitted by received-auth, when source masking is enabled.

[KnownFPClass] Unify and refine interested classes for `KnownFPClass::log` (#219751)
Previously, `ValueTracking` and `GISelValueTracking` only called
`KnownFPClass::log` when the requested classes included NaN or infinity.
As a result, narrowly interested queries could miss unconditional
deductions, for example, `log(x)` is never subnormal or negative zero
(With the exception of `PPCDoubleDouble`
https://github.com/llvm/llvm-project/issues/217658).
This change makes the interested-class handling consistent between
`ValueTracking` and `GISelValueTracking`. The source is queried only
when its classes are needed, but `KnownFPClass::log` is always called so
its unconditional deductions are preserved.
Future work:
- Fixing `KnownFPClass::log` for `PPCDoubleDouble`.
AI disclosure:
I used OpenAI Codex (sol 5.6) to help write the unit tests, which I
reviewed and ran locally.
README: point the build badge at SourceHut
Cirrus CI stopped running jobs on 2026-06-01 when Cirrus Labs joined OpenAI,
so the badge no longer renders and its link is dead. SourceHut has been
building poudriere since 2026-05-05 via .builds/freebsd.yml.
Fixes #1331
[SLP]Model copyable lanes of idempotent binops as op(V, V) when the operand column has a constant lane
The op(V, identity) form lets the reorder move the lane out of the
joined column, breaking the opcode-peer node; the symmetric form is
reorder-proof.

[SLP]Reduce logical and/or reductions in the wide leaf type
Logical and/or reductions on i1 with booleanized wide leaves (truncs
of same-op chains, zero-tests of values from [0, 1]) are performed in
the wide type, exposing the underlying consecutive values to the tree;
bit 0 of the result is the final value. Fixes the fragmented reduction
and the gather-of-scalars regression for compile-time-expanded Boolean
reductions.
