[lldb] Protect frame provider construction from re-entrant frame access
When a scripted frame provider calls HandleCommand or other
frame-accessing APIs during __init__, GetStackFrameList() re-enters
without the re-entrancy guard, causing infinite recursion. On Windows
(1MB default stack), this results in a stack overflow (0xC00000FD)
before Python's recursion limit can intervene.
The existing PushProviderFrameList/PopProviderFrameList guard only
protected GetFrameAtIndex calls in FetchFramesUpTo. This wraps the
CreateInstance call in LoadScriptedFrameProvider with the same guard
so that provider construction is also protected.

Fix lld/wasm/SyntheticSections.cpp after SyntheticSections.h #undef
SyntheticSections.cpp uses LLVM_DEBUG but had no #define DEBUG_TYPE,
relying on the leaked "lld" from SyntheticSections.h. Add an
explicit #define DEBUG_TYPE.
Fix lld/wasm/Relocations.cpp after SyntheticSections.h #undef
Relocations.cpp uses LLVM_DEBUG but had no #define DEBUG_TYPE,

[RISCV] Add TunePreferAscendingLoadStore for SpacemiT X60 LD/ST fusion (#186967)
Add a tune feature that reverses the callee-saved register spill/restore
order so that addresses are ascending, enabling LD/ST fusion on
processors like SpacemiT X60.

AMDGPU: Make VarIndex a WeakVH in AMDGPUPromoteAlloca (#188662)
The VarIndex might come from (like load) another alloca which maybe
promoted before. The value will replaced in this case. WeakVH correctly
handles this.
py-build: updated to 1.4.2
1.4.2 (2026-03-25)
Bugfixes
- Ensure the ``uv`` installer uses the current version of Python, avoiding an issue if ``UV_PYTHON`` is set, for example. (:issue:`977`)
- Fix ``_has_valid_outer_pip`` returning ``True`` when pip is missing, causing build to try using a non-existent pip
instead of falling back to virtualenv. (:issue:`1003`)
1.4.1 (2026-03-24)
Features
- Allow setting build constraints - by :user:`gaborbernat` (:issue:`963`)
- Automate releases with pre-release workflow and trusted publishing - by :user:`gaborbernat` (:issue:`991`)
Documentation
- Fix documentation grammar and typos (:issue:`979`)
- Reorganize documentation using Diataxis framework - by :user:`gaborbernat` (:issue:`988`)
- Document release process and workflow security practices in contributing guide (:issue:`991`)

Fix DebugInfo.cpp and Instructions.cpp after ConstantsContext.h #undef
Both files were relying on DEBUG_TYPE "ir" leaked from
ConstantsContext.h. Add explicit #define DEBUG_TYPE to each file.
Add #undef PASS_NAME to all files that define it
43 source files define a PASS_NAME macro that is never undefined,
which can leak into subsequent translation units in unity builds.
Add #undef PASS_NAME at the end of each file.
Delete error-check code that can never happen.
Near the top of kern_mmap() that implements the mmap(2) system call,
it sets
prot = PROT_EXTRACT(prot);
with
So prot can only be the three PROT_ flags.
The following test of the user's mmap(2) parameters (near line 275
in vm/vm_mmap.c):
if (prot != PROT_NONE &&
(prot & ~(PROT_READ | PROT_WRITE | PROT_EXEC)) != 0) {
return (EXTERROR(EINVAL, "invalid prot %#jx", prot));
}

[SparseTensor] Add missing #undef REMUI and DIVUI
LoopEmitter.cpp and SparseTensorIterator.cpp define REMUI and DIVUI
macros but the existing #undef block at the end of each file omits
them. This can leak the macros into subsequent translation units in
unity builds.
icu: updated to 78.3
Unicode® ICU 78.3 is a maintenance update on top of ICU 78 and 78.2, mostly for
the CLDR 48.2 bug fixes. In addition, it fixes a C++ code point iterator bug,
and updates to timezone data 2026a.
[SparseTensor] Add #undef FAILURE_IF_FAILED and ERROR_IF
Both DimLvlMapParser.cpp and LvlTypeParser.cpp define FAILURE_IF_FAILED
and ERROR_IF macros that are never undefined, which can leak into
subsequent translation units in unity builds. Add #undef at the end
of each file.
