[clang-apply-replacements] Change cleanup to only happen with --format (#178763)
Cleanup can result in many unrelated changes to the given replacements.
This change makes that only apply if the user actually wants
clang-apply-replacements to format their code outside of the
replacements.
[lldb] Add a new way of loading files from a shared cache (#179881)
Taking advantage of a few new SPI in macOS 26.4 libdyld, it is possible
for lldb to load binaries out of a shared cache binary blob, instead of
needing discrete files on disk. lldb has had one special case where it
has done this for years -- if the debugee process and lldb itself are
using the same shared cache, it could create ObjectFiles based on its
own memory contents. This new method requires only the shared cache on
disk, not depending on it being mapped into lldb's address space
already.
In HostInfoMacOSX.mm, we create an array of binaries in lldb's shared
cache, by one of two methods depending on the availability of SPI/SDKs.
This PR adds a new third method for loading lldb's shared cache off disk
as a proof of concept. It will prefer this new method when the needed
SPI are available at runtime. There is also a user setting to disable
this new method in case we uncover a problem as it is deployed.
I did change the internal store of the shared cache files from a single

[CMake][TableGen] Fix Ninja depslog error with implicit outputs on Ninja <1.10 (#179842)
Ninja versions prior to 1.10 cannot handle depfile mode when CMake
generates build rules with implicit outputs (the `| ${cmake_ninja_workdir}`
syntax used for IDE support). Ninja's depslog interprets these as
multiple outputs and rejects them with the error:
ninja: error: build.ninja:XXXX: multiple outputs aren't (yet?) supported
by depslog; bring this up on the mailing list if it affects you
This primarily affected builds where CMake generates NATIVE subdirectory
builds for host tools.
This patch modifies TableGen.cmake to:
1. Detect the Ninja version at configure time
2. Disable depfile mode (fall back to globbing .td files) when:
- Ninja version is < 1.10, OR
- The tablegen invocation produces multiple outputs (e.g. -gen-register-info)

administration: Remove stray horizontal rules
Horizontal rules are for separating sections of a document
without using headings. However, this page uses headings.
[libc++] Fix module builds for `<__algorithm/unwrap_range.h>` (#179887)
3a653afd45709432181952c0ffdb53eceb0939ae removed the inclusion of
`<__utility/declval.h>` from `<__algorithm/unwrap_range.h>`. However,
`unwrap_range.h` still needs to use `std::declval`. So we should restore
the inclusion.
The building failure with Clang modules was already caught by CI.
[RISCV] Remove P from RISCVISD::PASUB(U)/PMULHSU/PMULHR(U)/PMULHRSU. NFC (#180064)
There's a good chance we'll want to use these for scalar too.
Drop vector type from SDTypeProfile. Remove PMULHSU since we already
have RISCVISD::MULHSU for scalars in the base ISA.
Disable TestCancelAttach.py for linux -> linux remote (#180092)
This test was already disabled going from windows -> linux because it
was timing out there.
The PR: https://github.com/llvm/llvm-project/pull/179799 seems to have
exacerbated whatever this stall was, and now we're seeing it when
debugging from a linux host to a remote linux as well.
The native local host tests works correctly on all the bots that we
have, however. So I'm disabling the remote test till we can figure out
why this is problematic.

mandoc: Improve width calculation for GCC compat
Avoid implicitly converting a potentially negative page offset
to size_t and then back to int. While this was not a bug and the end
result was portably correct, Alexander Ziaee@ privately reported to me
that the GCC 14 in the FreeBSD Jenkins CI felt uneasy about it.
For clarity and readability, rewrite the truncation statement
to not mix signed and unsigned types, to not use explicit casts,
and make handling of the lower and upper cutoff more similar
to each other.
