[clang] Reject __super when preceded by a scope specifier (#221492)
The `__super` keyword is an MSVC extension that refers to the base class
of the current class context. It is fundamentally invalid for `__super`
to be qualified by another scope specifier (e.g. `::__super` or
`N::__super`).
Fixes #212988

[GlobalISel] When folding to fma correctly find fpext(fmul) with fewer uses (#218013)
When folding: `(fadd (fpext (fmul x, y)), z) -> (fma (fpext x), (fpext
y), z)` and both addends are candidates, correctly pick the side with
fewer uses. Previously the code looked for a `fmul` with the fewest uses
rather than a `fpext(fmul)`.

[X86] Prefer carry to overflow flag when using multiplication (#221611)
For all possible MUL/IMUL it will always output CF==OF, and CF is better
folding, so there's absolutely no reason the x86 backend should be
checking OF instead of CF for any form of multiply.
Did the change in FastISel too for consistency.
[MIPS] Support MIPS I hard-float double loads/stores with LWC1/SWC1 (#209362)
MIPS I lacks LDC1/SDC1. This patch implements double precision
loads/stores using LWC1/SWC1 instructions.
* Add BuildPairF64_FPR and ExtractElementF64_FPR nodes
* Use them in lowerLOAD/lowerSTORE for MIPS I hard-float
* Avoid redundant mtc1/mfc1 instructions
Matches GCC behavior for MIPS I hard-float.
Fix #62190.
[libc++][ranges] Implement LWG 3599 (#221573)
Implement [LWG 3599](https://wg21.link/LWG3599) by requiring
`forward_range<const Pattern>` for the `const` overloads of
`lazy_split_view::begin` and `end`.
This adds tests for disabled `begin()` and fallback `end()` on
non-const-forward patterns, as well as a regression test for
`view_interface::front()`.
Closes #189808
[Clang][Modules] Fix ODR handling of types found through using-declarations (#221839)
Fixes #78850.
Clang can diagnose an ODR violation for identical definitions when a
type is
found directly in one module's global module fragment and through a
using-declaration in another. The lookup routes produce different AST
type
wrappers even though they refer to the same declaration.
Normalize `UsingType` to the target declaration's type before hashing
it. Keep
the keyword and qualifier from the use site, rather than from the
using-declaration. This also lets the hash distinguish differently
qualified
uses without canonicalizing away meaningful spelling differences.
The normalization exposes an existing assertion in the enum ODR

[BOLT][RISCV] Mark newly created tail calls (#221672)
Tail calls created during CFG normalization lack the tail-call
annotation, so FixRISCVCallsPass rewrites them as regular calls that
clobber ra.
Set the annotation in createTailCall(). Clear builder annotations before
moving the originals when rebuilding calls to avoid duplicate annotation
markers.
Add a relocation-mode regression test for a conditional tail call.
[lld][MachO] Ignore relocated bytes when folding LSDAs (#220155)
AArch64 exception tables reference type info through PC-relative
pointer-to-GOT relocations. The assembler leaves the negated field
offset in each relocated field, which the linker ignores, so identical
tables differ in their raw bytes and are never folded. Treat
__gcc_except_tab like __eh_frame and zero the relocated fields before
ICF hashes and compares it.
Folding these LSDAs exposes a latent issue: the LSDA pointer of a DWARF
FDE is resolved to an InputSection when the FDE is parsed and is never
canonicalized after ICF. A function that is unwound via its FDE and
whose LSDA was folded away therefore gets an __unwind_info LSDA entry
computed from the dead input section. Fixed it in the same commit.
This patch is LLM-driven, but the issue was observed in production and
the test is reduced from the production object.
net/coturn: Update to 4.18.0
Upstream NEWS content, less bugfixes and minor improvements:
Release 4.18.0
Changelist:
- Deprecate option drop-invalid-packets (#2078) (Pavel Punsky <eakraly at users.noreply.github.com>)
avoid an uninitialised stack read
it is possible for bios_sysctl() to be called with namelen=0:
sys_sysctl() name={ CTL_MACHDEP, CPU_BIOS }, namelen=2
cpu_sysctl() name={ CPU_BIOS }, namelen=1
bios_sysctl() name={}, namelen=0
if name[0] was 2 (BIOS_DISKINFO) the function would not return ENOTDIR

Add openmp test to xfail list (#221854)
Introduced in PR #219323. Looking at the PR, and given we haven't yet
addressed openmp profcheck failures, the change is highly unlikely to
have introduced a new regression (it's exposing existing ones)
