AMDGPU: Validate processor is consistent with subarch in TargetID parsing
TargetID::parse checked that a named processor was a recognized GPU, but
not that it was consistent with the triple's subarch. A target id like
"amdgpu9.00-amd-amdhsa--gfx803" was accepted even though gfx803 does not
belong to the amdgpu9.00 subarch, silently taking the processor and
ignoring the mismatched subarch.

[VPlan] Drop redundant member LLVM_ABI annotations (#205767)
Classes that are annotated with `LLVM_ABI[_FOR_TEST]` should not have
individual member annotations. This PR drops the redundant member
annotations.
The effort to build LLVM as a dylib is tracked in #109483.
uvideo: fix step=0 infinite loop and int overflow in fbuf_size
Prevent infinite loop in uvideo_vs_negotiation() when a USB camera reports
step=0 in its continuous frame interval descriptor.
Cast fbuf_size calculation to uint64_t to avoid int overflow for large
width/height/bpp combinations.

clang/AMDGPU: Migrate cc1 tests to subarch triples (2)
Rewrite CodeGenCUDA cc1 test RUN lines from `-triple amdgcn... -target-cpu
gfxNNN` to the new subarch triple form, dropping the redundant -target-cpu.
Autogenerated CHECK lines are regenerated. Tests that intentionally assert
the "target-cpu" function attribute are left unchanged.

clang/AMDGPU: Migrate cc1 tests to subarch triples (3)
Rewrite CodeGenHIP cc1 test RUN lines to the new subarch triple form,
dropping the redundant -target-cpu, and regenerate autogenerated CHECK
lines. Tests whose behavior depends on the implicit wave32 default (which
is not enabled by a bare subarch triple) are left for a later change.

clang/AMDGPU: Migrate cc1 tests to subarch triples (1)
Mechanically rewrite cc1 test RUN lines from the old
`-triple amdgcn... -target-cpu gfxNNN` form to the new subarch triple
form (e.g. `-triple amdgpu9.00-amd-amdhsa`), dropping the now-redundant
-target-cpu. The subarch encodes the exact target, so the emitted IR no
longer carries a "target-cpu" function attribute; autogenerated CHECK
lines are regenerated accordingly.
This batch covers the small CodeGen, Frontend, Layout, and Preprocessor
test directories.

Kill the uvm_pmalloc mechanism. This never really worked, at least until
kirill@ fixed some page number/address confusement. But it can't really
work since pages freed by the pagedaemon are likely going to be grabbed
by other consumers before we issue a wakeup through the uvm_pmalloc
mechanism. At this point the consensus is that it adds complexity to the
pagedaemon that stands in the way of progress.
Discussed with claudio@ and deraadt@

libsysdecode: add Netlink attribute decoding infrastructure
Introduce a generic Netlink attribute decoding framework based on
attribute decoder tables. The framework supports decoding primitive
attribute types as well as nested attributes and can be reused by
different Generic Netlink families.

[AMDGPU] Fix incorrect grid_dims constant folding for reqd_work_group_size (#211285)
reqd_work_group_size(X, Y, 1) does not guarantee the dispatch runs with
work_dim == 2, since the spec still allows enqueuing with work_dim == 3
and a unit-size Z dimension. Only fold hidden_grid_dims to a constant
when Z != 1 (work_dim must be 3)
Otherwise tighten the range instead of assuming an exact value
Alterative approach to https://github.com/llvm/llvm-project/pull/205866

[OFFLOAD][L0] Properly consume errors in program validation (#211799)
Some of the program unittests were failing because errors weren't

[lldb][test] Skip frame-recognizer argument tests on WebAssembly (#211807)
The recognizer reads arguments through $arg1/$arg2, which resolve via
argument registers. WebAssembly has no argument registers and no ABI
plugin, and these tests build without debug info, so there is no
location to read the arguments from and they come back as zero.
[lldb] Skip the WebAssembly function header for frame recognizers (#211806)
A frame recognizer restricted to the first instruction matches when the
frame's PC equals the function's start address. On WebAssembly a
function begins with a non-executable local variable header, so the
symbol's start address is never a value the PC can take and such
recognizers never matched.
Route the start address through Architecture::SkipFunctionHeader, which
already maps a function start past this header for breakpoints and
disassembly, so the comparison uses the first executable instruction.
[flang][OpenMP] Implement the error directive (#206175)
## [flang][OpenMP] Implement the `error` directive
### Summary
Implements the OpenMP `error` directive (OpenMP 5.1, 2.5.4) in Flang.
The directive prints a message and, with `severity(fatal)`, stops.
Handling depends on the `at` clause:
- **`at(compilation)`** (the default): handled in semantics. Emits a
compile-time warning or error and produces no IR.
- **`at(execution)`**: lowered to a new `omp.error` op, which becomes a
call to `__kmpc_error`.
Before this patch the directive was unimplemented and hit a `not yet
implemented: OmpErrorDirective` error during lowering.
Fixes #204240.

[LifetimeSafety] Support container interior paths and invalidations
This patch completes the implementation of path-sensitive lifetime tracking by supporting container interior paths (`.*`) and deep-nested invalidation.
- Enables `PathElement::getInterior` generation in `FactsGenerator` for GSL Owners and Views (e.g. member functions, function parameters, lambda captures).
- Removes bypass checks in `FactsGenerator::handleInvalidatingCall` to track container invalidation on fields.
- Updates `Checker` to use strict prefix comparison (`isStrictPrefixOf`) for container invalidations, ensuring invalidation of container contents (interior) correctly invalidates iterators but not other sibling fields.
- Reorganizes tests in `invalidations.cpp` by resolving duplicates and distributing them logically.
- Updates unit tests and sema tests with correct expectations for interior paths.

[SystemZ][z/OS] Add the OF_Text flag to read .ll files and parse assembly files (#211782)
This patch allows us to parse .ll files in verify-uselistorder correctly
and fixes failures in any testcase that uses this tool.
[LifetimeSafety] Support field-sensitivity in lifetime tracking
This patch enables field-sensitivity when tracking lifetimes of nested objects.
- FactsGenerator now generates `PathElement::getField` for `MemberExpr` accesses, mapping fields to loans.
- LoanPropagation now propagates field paths along flow facts, appending fields to base loans.
- Removes false-positive warnings in `invalidations.cpp` where modifications to one field were incorrectly reported as invalidating iterators/pointers to another field.
- Adds comprehensive unit tests checking nested field access and placeholder fields.
