[X86][NFC] Use compact enum in TargetParser (#206088)
ProcessorDefs and FeatureInfoDefs store strings together with constant
data. Use the compact enum tables to avoid dynamic relocations for the
strings.
[libc++] Fix shared_ptr rebinding allocators to incomplete types (#206145)
https://github.com/llvm/llvm-project/pull/200401 caused various ways to
create a `shared_ptr` control block to reject any allocators which
required a complete type. This patch allows allocators to again require
a complete type.

Do not remove support for https neither at compile time (SMALLPROG)
nor at runtime (no SSL trust anchors available).
Instead dynamically disable the https option when it won't work, but
fully support it later (after unpacking the base set) when downloading
stuff for binary pkgs or pkgsrc.

[mlir][linalg] Restrict linalg.contract results (#205988)
I tightened linalg.contract so buffer-style uses cannot produce memref
results. This keeps the op consistent with destination-style semantics
and turns the bad input into a verifier error instead of letting later
rewrites crash.

libdtrace: Fix dt_print_sym() not printing symbols in non-oformat mode
dt_print_sym() fills the symbol string via snprintf() in non-oformat
mode but the guarding `dtp->dt_oformat != 0 &&` for the dt_printf()
call causes the symbol is computed but never emitted.
This fixes tests:
- common.profile-n.t_dtrace_contrib.tst_sym_ksh
- common.profile-n.t_dtrace_contrib.tst_func_ksh

[lldb][driver] Fix ELF interposition of HostInfoBase symbols causing segfault (#204710)
Commit 67e571d (#179306) added lldbHost and lldbUtility to
`LLDB_DRIVER_LINK_LIBS` A side-effect is that HostInfoBase.cpp, which
contains the file-static `g_fields` pointer, is now compiled into both
the lldb binary and liblldb.so, giving each its own independent
`g_fields`.
On ELF platforms this creates an interposition hazard. When
`LLDB_ENABLE_DYNAMIC_SCRIPTINTERPRETERS` is set, AddLLDB.cmake switches
all LLDB libraries to `CXX_VISIBILITY_PRESET=default` so that the
version script can re-export private symbols needed by dynamically
loaded plugins. The Python plugin calls `HostInfo::GetShlibDir()`
directly, so extract-dynamic-script-interpreter-exports.py adds
`HostInfoBase::GetShlibDir` to liblldb.so's exports (global: in the
version script). `HostInfoBase::Initialize()` is not called by the
plugin and stays local:.
At runtime the dynamic linker resolves liblldb.so's PLT entry for

Revert "[lit] Migrate lit to ProcessPoolExecutor (#202681)" (#206138)
This reverts the commit 1e2d1bbc12f6.
ProcessPoolExecutor.shutdown(wait=True) hangs on macOS 14 with Python 3.9: join_executor_internals() calls call_queue.join_thread() before p.join(), but macOS requires the inverse order. The feeder thread cannot drain until worker processes are joined, so join_thread() blocks forever. This is fixed upstream in CPython >= 3.12 but affects all earlier versions on macOS. Reverting to unblock the aarch64-darwin buildbot while a proper fix is worked out.

[WebAssembly] Fix nondeterminism by using MapVector for pointer-keyed maps [NFC] (#205184)
Several DenseMaps in the WebAssembly backend keyed by pointers were
being
iterated over, potentially leading to nondeterministic codegen
(differing
try/delegate nesting, virtual register allocation, or PHI node
insertion)
due to nondeterministsic pointer values.
This patch replaces these DenseMaps with MapVectors to guarantee
deterministic iteration order:
- UnwindDestToTryRanges in WebAssemblyCFGStackify.cpp
- EHPadToUnwindDest in WebAssemblyCFGStackify.cpp
- EHPadToRethrows in WebAssemblyLateEHPrepare.cpp
- UnwindDestToNewPreds in WebAssemblyLowerEmscriptenEHSjLj.cpp
