[ELF] Scan .eh_frame relocations first. NFC (#235389)
.eh_frame is usually the largest item, so one thread scans it while the
others are idle. Hand it out first.
[LLDB] Skip Undef Symbol when resolving ReExportedSymbol
An undef symbol cannot be resolved. Skip it so that a symbol needs no
Resolve can pass. Without this, a symbol that needs no ReExport resolver
can choose the undef symbol incorrectly.

[Allocator] Cap MinAlign at alignof(max_align_t) (#235373)
alignof(std::max_align_t) is 4 on NetBSD/i386, whose <stddef.h> defines
max_align_t as a union of void *, long double, and long long.

share/mk/bsd.confs.mk: fix trivial typo in message
The error message noting that the file should not be included said
"bsd.conf.mk" before this change. Now it correctly says "bsd.confs.mk".

[BPF] Disambiguate CO-RE relocation globals (#234252)
The BPF backend encodes the relocation kind, local value and access path
in a global name. Type names such as `S<ns::Arg$>` can contain both
delimiters. Decode the fixed suffix from the right in instruction
folding and BTF emission. This fixes the compiler crash reported in
#233947.
Within a module, different debug types can produce the same name. A
pointer access and a 32-bit field-offset query can also have the same
name with different load types. Reuse an external relocation global only
when its debug root and load type match. Put any discriminator before
the suffix so both consumers read the original relocation.

[libunwind] Support extended amd64 segment registers (#229176)
Raise the amd64 DWARF register limit to 59 and add RFLAGS, all six
segment selectors, FS.base, and GS.base to the register model. Capture
the extended state and restore it when resuming, using sigreturn() on
FreeBSD to restore selectors and bases together. Pack the state into the
existing context buffers without changing their public sizes or the
Windows XMM offsets.
Add tests for register access, signal-frame CFI recovery, register
bounds, and resume behavior.

[lldb][bazel] Add targets for the remaining unconditional plugins (#235325)
CMake builds these plugins on every host, but the Bazel overlay had no
targets for them:
- PluginABILoongArch
- PluginDynamicLoaderFreeBSDKernel
- PluginPlatformAIX
- PluginPlatformFreeBSD
- PluginPlatformNetBSD
- PluginPlatformOpenBSD
- PluginTypeSystemClike
I also added these to the DEFAULT_PLUGINS list.
For now, I'm still leaving out plugins that CMake only builds with an
optional dependency or on a specific host:
- ProcessFreeBSDKernelCore (FreeBSD hosts, libkvm)

Update devel/ocaml-ppxlib to version 0.33.0.
0.33.0 (2024-07-22)
-------------------
- Fix a bug where `Code_path.main_module_name` would not properly remove
extensions from the filename and therefore return an invalid module name.
(#512, @NathanReb)
- Add `-unused-type-warnings` flag to the driver to allow users to disable
only the generation of warning 34 silencing structure items when using
`[@@deriving ...]` on type declarations. (#511, @mbarbin, @NathanReb)
- Make `-unused-code-warnings` flag to the driver also controls the generation
of warning 34 silencing structure items when using `[@@deriving ...]` on type
declarations. (#510, @mbarbin, @NathanReb)
- Driver: Add `-unused-code-warnings=force` command-line flag argument. (#490, @mbarbin)

[MemorySSA] Remove unused functions (NFC) (#235374)
Remove MemoryPhi::unorderedDeleteIncomingValue, upward_defs and
ClobberWalker::const_def_path, which have no callers, together with the
const_def_path_iterator alias only used by const_def_path.
Merge tag 'tty-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty / serial driver updates from Greg KH:
"Here is the "big" set of tty and serial driver updates for 7.4-rc1.
It's not really all that big, it's been kind of quiet in this area of
the tree this development cycle in relation to other parts of the
tree. But still, included in here are:
- 8250 port updates and fixes
- 8250 driver cleanups by Jiri
- deletion of the obsolete moxa driver (making this pull request
remove more lines than added!)
- different serial driver updates for dma and other reported issues
All of these have been in linux-next with no reported problems"

Build minivmac with -fno-strict-overflow to fix a crash on macppc.
Patch the port to use CC and CFLAGS and not strip(1). Build
DEBUG_PACKAGES. Put myself as MAINTAINER.
A pointer might have wrapped around NULL, which is undefined behavior
in C. clang-local(1) -wrapv stopped affecting pointers when we
updated clang from 19 to 22.
