[PowerPC] Hardcode LDAT/LWAT_CSNE constant immediate (#196115)
The FC field in LDAT/LWAT_CSNE instructions is always 16, so hardcode it
in the TableGen definition instead of passing it as an explicit operand.
all: drop support for FreeBSD 13, mips and risc64sf

Fix metadirective loop variant lowering
Preserve the associated DO evaluation when a dynamic metadirective can
select either a loop-associated directive or a standalone fallback, so
the fallback still lowers the original loop body.
Scope temporary loop-IV data-sharing attributes to the selected variant.
Use the selected variant's collapse clause to determine how many loop IVs
to mark, avoiding DSA state leaking between alternatives.
[flang][OpenMP] Support loop-associated metadirective variants (part 3)
Enable metadirective lowering for loop-associated variants such as
`do`, `simd`, `parallel do`, and `do simd`.
When a metadirective resolves to a loop-associated directive, the
sibling DO evaluation is spliced into the metadirective's evaluation
list so existing loop lowering finds it. Loop IV data-sharing
attributes are marked at lowering time since semantic analysis cannot
know which variant will be selected. The DataSharingProcessor is also
extended to handle spliced evaluations.
This patch is part of the feature work for #188820 and stacked on top
of #194424.

[NFCI][msan] Add test case for llvm.fptoui.sat/llvm.fptosi.sat (#196416)
Forked from llvm/test/Instrumentation/MemorySanitizer/ftrunc.ll
PR #191365 lowered NEON fcvtz[us] intrinsics into fpto[us]i.sat,
exposing a gap in MSan's instrumentation. A follow-up patch will add
support in MSan for ftop[us]i.sat, propagating the shadow (similar to
its handling of fcvtz[us]) rather than strictly handling them.
[Instrumentor] Allow printing a runtime stub (#138978)
This commit extends the Instrumentor with the option
`configuration.runtime_stubs_file` to generate a runtime stub file with
the configured instrumentation. The stub prints all parameters passed to
each enabled instrumentation function.
[NewPM] Port for AArch64SLSHardening (#196378)
AArch64.h: Declared the AArch64SLSHardeningPass class.
AArch64PassRegistry.def: Registered the pass under the name
aarch64-sls-hardening.
AArch64SLSHardening.cpp: Implemented the run method to bridge the NewPM
with the existing pass logic, ensuring MachineModuleAnalysis is
correctly retrieved.
[clang][RISCV] Remove some of the bits added with RISC-V big endian support (#192903)
- FreeBSD will not have any new 32-bit archs
- *BSD's are unlikely to touch BE RISC-V
- Keep the BE and LE targets separate
Fix LOCAL_PEERCRED in 32-bit compat mode
Previously the cr_pid field would be incorrectly copied to userland, due
to a size mismatch between the structure as defined in 32-bit vs 64-bit
builds. Fix it by converting the structure before copying it to
userland.

[CIR] Implement weak ref and alias attribute handling (#195972)
This adds handling for globals with the WeakRefAttr (not emitted) or
AliasAttr attributes set. CIR already had support for function aliases,
but we weren't handling the explicit alias attribute, and we didn't have
any support for global variable aliases. This change adds the global
variable alias support and adds the code to handle the explicit
attribute for variables and functions.

nullfs: Clear inotify flags during reclaim
The inotify flags are copied from the lower vnode into the nullfs vnode
so that the INOTIFY() macro will invoke VOP_INOTIFY on the nullfs vnode;
this is then bypassed to the lower vnode. However, when a nullfs vnode
is reclaimed we should clear these flags, as the vnode is now doomed and
no longer forwards VOPs to the lower vnode.
Add regression tests. Remove a test in vn_inotify_revoke() which is no
longer needed after this change.

tests/socket_afinet: Fix the bind_connected_port test
The test verifies that a socket can bind to a local address assigned by
connect(2) to a different socket. It was however trying to bind to the
wrong address, and the check of the result was inverted, so this went
unnoticed. It also needs to set SO_REUSEADDR for this to succeed.
