Mk/Uses/npm.mk: Add new variable NPM_PREFETCH_ARCHS
A node modules archive created by the prefetch function may vary
depending on the architecture, especially if the archive contains
architecture-specific node modules.
This variable can be used to indicate which architectures the node
modules archives are prepared for.
If you prepared the archives for amd64 and aarch64 architecutres,
specify:
NPM_PREFETCH_ARCHS= aarch64 amd64
[clangd][clang-tidy] Factor out mergeFixits() logic and reuse it in clangd (#208682)
This patch extracts `mergeFixits()` from `DiagnosticRenderer` to
`clang::edit` and reuses it in clangd. This prevents syntax errors
caused by token merging when applying clang-tidy fixits via clangd.
Fixes #207618
[DWARFLinker] Index Swift mangled type names in the parallel linker (#216429)
Swift records a type's mangled name in DW_AT_linkage_name. The classic
linker indexes it as a type accelerator entry alongside the short
DW_AT_name, but the parallel linker indexed only the short name.
Port the DW_LANG_Swift block added to the classic linker in 8234f8ae2685
to the parallel linker's type case.
libxml2: update to 2.15.3.
From Showta Ishizaki in PR 60591.
v2.15.3: Apr 15 2026
### Security
- parser: Pass userData to SAX text callbacks in xmlParseReference (type-confusion)
- entities: copy children in xmlCopyEntity
- c14n: Fix Type confusion in xmlC14NProcessAttrsAxis
- python: Do not decref string after adding to the list (double-free / use-after-free)
- c14n: Reuse tmp_str, xmlStrcat reallocates *cur (double-free)
### Improvements
- schemas: Fix relative schemaLocation resolution in XSI assembly in streaming mode
- xmlreader: propagate reader resource loaders to validator parsers
- python: Make python bindings python2 compatible

[SLP]Recalculate copyable-element deps after tree reordering
Reordering permutes the operand columns of the entries and may move an
operand between copyable-covered and plain edges, making the computed
dependency counts stale and tripping the unscheduled-deps assertion.
