   debug/shl.mi: Cull obsolete linkable shlibs and explain why.

   This is not a _good_ system but it's the system we have:

   PR misc/57581: set lists should have a way to obsolete shlibs in
   DESTDIR but not in postinstall

Fix cir vec cmp fold (#202502)

Fixes #202431

This PR fixes two bugs in `VecCmpOp::fold` that caused incorrect
constant folding of vector comparisons.

1. Wrong result value: True comparison results were folded to 1, but the
SIMD convention and `VecCmpOp`'s own documentation require 0 (false) or
-1 / all-ones (true). For example, a `ne` comparison where all elements
differ should produce [`-1, -1, -1, -1]`, not `[1, 1, 1, 1]`.

2. Unsigned comparisons treated as signed: Ordered comparisons `(lt, le,
gt, ge)` always used `getSInt()`, treating unsigned element types as
signed. This produced wrong results for values whose high bit is set,
e.g., for `u8`, the value 255 was interpreted as -1, so 0 > 255
(unsigned: false) was incorrectly folded to true.

Fix: Dispatch to `getUInt()` or `getSInt()` based on the input element

[flang][cuda] Exclude non-variable actuals from unified-memory CUDA data attribute relaxation (#206121)

Under -gpu=mem:unified, the CUDA data attribute compatibility check
(AreCompatibleCUDADataAttrs) allows an unattributed actual argument to
bind to a Device/Managed/Unified dummy. This relaxation is correct for
variables whose storage is accessible from device code under unified
memory, but not for non-variable expression results (e.g. intrinsic call
results like RESHAPE(...)), which are host temporaries.

Without this fix, a generic SUM call like sum(reshape(hostArray, ...),
dim=2) could resolve to a device-specific overload instead of the
intrinsic, because the RESHAPE result was incorrectly considered
compatible with a DEVICE-attributed dummy.

This patch:

- Adds an actualIsVariable parameter to AreCompatibleCUDADataAttrs
(defaulting to true for backward compatibility) and gates the
unified-memory relaxation for Device/Managed/Unified dummies on it.

[docs] Register MLIR lexer for Sphinx docs

Register the in-tree MLIR Pygments lexer from the shared llvm_sphinx configuration so all llvm-project Sphinx builds can highlight fenced mlir blocks.

Also teach the MLIR lexer to consume top-level whitespace. Without this, Sphinx reports a lexer warning after the lexer is registered, and docs-clang-html fails because Sphinx warnings are treated as errors.

This makes docs-clang-html build with CLANG_ENABLE_CIR=ON.

   t_mbrtowc: Mark UTF-8 test cases xfail.

   mbrtowc previously failed to reject invalid (legacy 5/6-byte) UTF-8,
   so it accepted this test case.  Now it rejects this test case,
   because the test case itself is broken.

   Need to split this test up into:

   1. correctly decoding the valid inputs
   2. correctly rejecting the invalid inputs

   But for now marking the test case xfail is an adequate approximation
   to the more complicated truth.

   PR lib/60369: mbrtowc, mbrlen have wrong return value for some
   invalid byte sequences: Invalid sequence

[clang][docs] Register MLIR lexer for CIR docs

Register the in-tree MLIR Pygments lexer with Clang Sphinx docs so generated CIR dialect documentation can highlight fenced mlir blocks.

Also teach the MLIR lexer to consume top-level whitespace. Without this, Sphinx reports a lexer warning after the lexer is registered, and docs-clang-html fails because Sphinx warnings are treated as errors.

This makes docs-clang-html build with CLANG_ENABLE_CIR=ON.
