[libc][math] Refactor sqrt to header-only (#178335)
This refactors `sqrt` to be header-only, following the libc math
refactoring plan.
Part of #147386
Closes #177648
[lldb] Add support for ScriptedFrame to provide values/variables.
This patch adds plumbing to support the implementations of StackFrame::Get{*}Variable{*} on ScriptedFrame. The major pieces required are:
- A modification to ScriptedFrameInterface, so that we can actually call the python methods.
- A corresponding update to the python implementation to call the python methods.
- An implementation in ScriptedFrame that can get the variable list on construction inside ScriptedFrame::Create, and pass that list into the ScriptedFrame so it can get those values on request.
There is a major caveat, which is that if the values from the python side don't have variables attached, right now, they won't be passed into the scripted frame to be stored in the variable list. Future discussions around adding support for 'extended variables' when printing frame variables may create a reason to change the VariableListSP into a ValueObjectListSP, and generate the VariableListSP on the fly, but that should be addressed at a later time.
This patch also adds tests to the frame provider test suite to prove these changes all plumb together correctly.

[lldb] Add conversions for SBValueList and SBValue to the python bridge.
This patch adds support for:
- PyObject -> SBValueList (which was surprisingly not there before!)
- PyObject -> SBValue
- SBValue -> ValueObjectSP using the ScriptInterpreter
These three are the main remaining plumbing changes necessary before we can get to the meat of actually using ScriptedFrame to provide values to the printer/etc. Future patches build off this change in order to allow ScriptedFrames to provide variables and get values for variable expressions.

[lldb] Move ValueImpl and ValueLocker to ValueObject, NFC.
This patch moves ValueImpl and ValueLocker to ValueObject.{h,cpp}. This follows the example set in TypeImpl/SBType, where we have something that SBType uses internally that needs to be exposed in the layer below. In this case, SBValue uses ValueImpl, which wraps ValueObject. The wrapper helps avoid bugs, so we want to keep it, but the script interpreter needs to use it and said interpreter is conceptually *below* the SB layer...which means we can't use methods on SBValue.
This patch is purely the code motion part of that, future patches will actually make use of this moved code.

[Offload][AMDGPU] Fix olQueryQueue uninitialized output parameter (#178464)
## Summary
- Fix uninitialized output parameter in `olQueryQueue_impl` when
`Queue->AsyncInfo->Queue` is null
- Set `IsQueueWorkCompleted` to `true` when no underlying queue exists
(no pending work)
- Resolves test failure on AMDGPU for
`olQueryQueueTest.SuccessEmptyAsyncQueueCheckResult`
Fixes #178462.
## Test plan
- [x] Fixed
`OffloadAPI/queue.unittests/olQueryQueueTest/SuccessEmptyAsyncQueueCheckResult/AMDGPU_AMD_Radeon_RX_7700_XT_0`
test
- [ ] CI tests pass

[LoongArch] Support `preserve_none` calling convention
Add support for the `preserve_none` calling convention on LoongArch.
Registers `R4-R20` and `R23-R31` are treated as caller-saved and may be
used for argument passing, except for `R31`.

[NFCI][ELF][Mips] Refactor MipsGotSection to avoid explicit writes (#178561)
Splitting the VA / addend calculations between build and writeTo means
having to keep them in sync and duplicating some of the logic. Move all
such calculations into build, mirroring how the normal non-MIPS code in
Relocations.cpp ensures the addend and initial memory contents are set.
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.

[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.
