[SSAF][Extractor] Make hard errors in Extractors quiet
Hard errors were used in extractors during development to quickly
identify unsupported language constructs. This commit converts them to
DEBUG_WITH_TYPE so that these errors are silenced in release builds.

[clang][lex] Store `HeaderFileInfo` in a `MapVector` (#201936)
This is a re-commit of PR #200968 (f357a47) that was reverted by PR
#201702 (adaa9e0). One call-site of
`HeaderSearch::forEachExistingLocalFileInfo()` in `ASTWriter` relies on
stable order, which the `DenseMap` didn't provide. This PR switches to
`MapVector`, which has the same performance characteristics as the
original solution at the cost of a theoretical memory usage increase.
Original PR description:
Calling `FileManager::GetUniqueIDMapping()` during modular builds gets
very expensive if the `FileManager` has seen lots of files. This
function is used in two places in the `ASTWriter` to look up
`HeaderFileInfo` in `HeaderSearch`.
This PR changes the storage of `HeaderFileInfo` from
`FileEntry::getUID()`-indexed `std::vector<T>` to
`llvm::DenseMap<FileEntryRef, T>`, improving scanning performance by
~2.5%.
Reland "Remove the optional bitcast between a musttail call and its ret" (#201280) (#201642)
This relands #201280, which was reverted in #201479 because it broke the
sanitizer buildbot
The revert was caused by a heap-use-after-free in
`BitcodeReader::materialize`
Fix: The CallBase branch could have erased I before we read it in the
new conditional
[Flang][OpenMP] Support iterator modifiers in map and motion clauses
Support iterated array elements and array sections in map and motion clauses for
target data, target enter data, target exit data, and target update constructs.
Preserve mapper resolution for iterated entries, including explicit mappers,
user-defined default mappers, declare mapper entries, and implicit default
mappers.
This PR stacked on top of #197047 and #197752.
This patch is part of the feature work for #188061.
Assisted with copilot.
audit: Replace TAILQ with STAILQ
This reduces the size of a trigger entry from 24 bytes to 16 (or from
12 bytes to 8 on 32-bit) with no additional complexity.

audit: Add poll / select support
It was previously not possible to poll() or select() on the trigger
device, which made implementing proper signal handling in auditd
difficult.

[SSAF] Let function parameters inherit linkage from their parent functions
SSAF treats parameters as entities and may not always associate them
back to their parent functions. Therefore, it needs to identify
parameters of functions with external linkage across different
TUs. Treating them as having no linkage (as in C++) causes the same
parameter in different TUs to be assigned different EntityIDs. As a
result, the behavior of the parameter across multiple TUs cannot be
correlated.

[DirectX][ObjectYAML] Add SRCI part support (#199446)
Add support for DXContainer SRCI in the ObjectYAML pipeline so it can be
represented in structured YAML and round-tripped through
yaml2obj/obj2yaml.
SRCI is emitted into shader PDB files. It stores shader source code that
is displayed in PIX, and shader compilation flags.
[flang][OpenMP][NFC] Share declare mapper helpers for iterator modifier lowering
Move mapper lookup and implicit default mapper creation into reusable
OpenMP lowering helpers so regular map lowering and iterator-generated
map entries can use the same resolution path.
This prepares Flang iterator modifier lowering for map and motion clauses
without changing the generated IR for existing non-iterator maps.
[DirectX] Rewrite DIGlobalVariableExpression to DXDIGlobalVariable (#199791)
DIGlobalVariable used to have an `expr` operand. Starting from
bceaaa964360 `expr` is now an operand of DIGlobalVariableExpression,
which references both the variable and the expression.
Before:
!0 = !DIGlobalVariable(expr: !1)
!1 = !DIExpression(DW_OP_plus, 4)
Now:
!2 = !DIGlobalVariableExpression(var: !3, expr: !4)
!3 = distinct !DIGlobalVariable(name: "a", scope: null, isLocal: false,
isDefinition: true, type: !6)
!4 = !DIExpression(DW_OP_plus, 4)
DXIL does not support DIGlobalVariableExpression, so we have to fold
`expr` back to DIGlobalVariable.

[lld-macho][LTO] Emit `__llvm_addrsig` for `--icf=safe_thunks` (#188486)
LTO was emitting `__llvm_addrsig` metadata when `--icf=safe` was
specified, but not for `--icf=safe_thunks`. After the recent PR
https://github.com/llvm/llvm-project/pull/188400 that makes safe ICF
conservative without `__llvm_addrsig` (marking all symbols as
address-significant when the section is absent), this omission caused
safe_thunks to silently degrade for all LTO-compiled objects: every
symbol became `keepUnique`, preventing body folding entirely.
Fix this by also enabling `EmitAddrsig` when `icfLevel` is
`safe_thunks`. This allows the LTO backend to emit precise
address-significance metadata, so that only truly address-significant
functions get thunk treatment while non-address-significant identical
functions can still be body-folded.
Add a regression test that verifies LTO + `--icf=safe_thunks` correctly
body-folds non-address-significant identical functions, which would fail
without this fix due to missing addrsig metadata.
