[FileCheck] Add a diff output option for FileCheck (#187120)
This patch adds a `--diff` flag to FileCheck to address the readability
of traditional FileCheck output which can be difficult to parse by
human, especially when dealing with multiple substitutions or large
input files with many mismatches and additional context. This feature
provides a more familiar, scannable format for developers by rendering
mismatches as diffs.
There are two diff modes, split and unified both with substitution and
no-substitution version however to make it easier for reviewer, this
only have unified with no substitution.
Functional description of PR-
`getDiffContext` -
It provides the surrounding context for the mismatch. It uses the
`SourceMgr` to find the Line using `LineNo`. Once it found the pointer,
it scans forward until it hits a newline (\n or \r) or the end of the

[OFFLOAD] Introduce OpenMP math wrappers for SPIRV backend (#192139)
This PR is a first step to introduce math OpenMP wrappers for SPIRV
backend.
As a first step only API that either mapped to existing SPIRV API or has
straightforward implementation is introduced.
SECURITY update to cups-2.4.17.
- CVE-2026-27447: The scheduler treated local user and group names as case-insensitive.
- CVE-2026-34978: The RSS notifier could write outside the scheduler's RSS directory.
- CVE-2026-34980: The scheduler did not filter control characters from option values.
- CVE-2026-34979: The scheduler did not always allocate enough memory for a job's options string.
- CVE-2026-34990: The scheduler incorrectly allowed local certificates over the loopback interface.
- CVE-2026-39314: Fixed the range check for job password strings.
- CVE-2026-39316: Fixed a printer subscription bug in the scheduler.
- CVE-2026-NNNNN: Fixed a SNMP string conversion bug in the backends.

[clang] Improve diagnostics for `__builtin_align` builtins with floating/member pointer operands (#192650)
Improve diagnostics for `__builtin_align_up`, `__builtin_align_down`,
and `__builtin_is_aligned` when the first operand has an invalid type.
Clang already emits `err_typecheck_expect_scalar_operand` for
unsupported operands, but the message is generic. This patch adds
follow-up notes to clarify three common invalid cases:
* floating point operands (“floating point types are not allowed here”)
* C++ member pointer operands (“member pointers are not allowed here”)
* plain-function-pointer ("function pointers are not allowed here")
[LoongArch] Select `V{AND,OR,XOR,NOR}I.B` for bitwise with byte splat immediates (#192217)
The `V{AND,OR,XOR,NOR}I.B` instructions operate on byte elements and
accept an 8-bit immediate. However, when the same byte splat constant is
used with wider vector element types (e.g. v8i16, v4i32, v2i64),
instruction selection currently falls back to materializing the constant
in a temporary register.
```
vrepli.b -1
vxor.v
```
even though the immediate form is available:
```
vxori.b 255
```
