Add support for DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt. (#176056)
LLDB's DWARF parser didn't support parsing DW_FORM_GNU_ref_alt and
DW_FORM_GNU_strp_alt forms which would cause any file loaded by LLDB to
fail to parse any DWARF. Added support for parsing this information
only, not for actually finding the debug info reference to an alternate
file or a string in an alternate file. These extensions are used by DWZ
files which are present in some linux distros, so it will be good for
LLDB to just be able to parse these without emitting an error like:
(lldb) b bar
warning: (arm64) /tmp/a.out unsupported DW_FORM values: 0x1f20 0x1f21
[lldb] Add the ability to load ELF core file executables and shared libraries from memory (#177289)
This patch enables ELF core files to be loaded and still show
executables and shared libraries. Functionality includes:
- Load executable and shared libraries from memory if ELF headers are
available
- Create placeholder for missing shared libraries and executable.
Previously you just wouldn't get anything in the "image list" if no
executable was provided.
[SLP]Do not vectorize subtrees of the split node, marked as gathers.
If the split node was marked as gather/buildvector nodes, the vectorizer
should not vectorize its subtrees, which are marked as deleted.
[lldb-dap] Adding more details to 'exceptionInfo'. (#176465)
In the exceptionInfo request I've added additional information for crash
data, instrumentation data and more detailed exception data.
For example, when UBSan is enabled, you now see additional information
in the exception stack trace about the detected issue:
<img width="1728" height="538" alt="Screenshot 2026-01-15 at 3 05 08 PM"
src="https://github.com/user-attachments/assets/b761af2c-90ac-4eb7-9926-3ab133f1b753"
/>
I included a new test for stopping at `lldb::eStopReasonInstrumentation`
and ensuring we have additional information reported.

gtest.cc: declare fail_if_no_test_linked flag
Clang's -Wmissing-variable-declarations flags this as an issue since the
flag is only used in `gtest.cc`. Declare the flag beforehand to ensure
that the variable scope is properly limited to `gtest.cc`.

[Clang][Sema] Avoid crash in overload diagnostics for invalid static deducing-this (#177783)
Fix #177741
Overload candidate diagnostics reserve a conversion slot for the object
argument. For static methods this slot does not correspond to a real
parameter, and for ill-formed declarations with an explicit object
parameter we could index past the parameter list and crash in assert
builds.
Use isExplicitObjectMemberFunction() when mapping conversion slots to
parameters and guard parameter-range computation to keep notes robust.
sysutils/bup: Update to 0.33.10
(Significantly, bup's tests now pass on NetBSD, with many test issues resolved.)
Upstream NEWS:
Notable changes in 0.33.10 since 0.33.9
=======================================
Bugs
----
* As noted in 0.33.8, `bup fsck` switched from symlinks to hardlinks
to accommodate an incompatible change in `par2` 1.0's behavior. To
allow the use of filesystems without hardlinks, `bup` now copies the
input files if hardlinking fails.
Thanks to (at least)

[Github] Filter only origin branches in prune unused branches workflow
We should only have branches from the origin remote when actually
running the workflow, but this makes the script easier to test locally
where I have branches from several different remotes.
