[libc++] Resolve LWG4308, correct `iterator` availability for `optional<T&>` (#173948)
Resolves #171345
Implements [proposed resolution for
LWG4308](https://cplusplus.github.io/LWG/issue4308) and removes
`const_iterator` from `optional<T&>`, which was missed.
- Constrains iterator to only be available if T is not an lvalue
reference, or if it is T&, that T is an object type and is not an
unbounded array
- Add a partial specialization for `__optional_iterator` for `T&`, which
only has the `iterator` type.
- Correct a static assert message as a drive-by
- Move the libcxx specific iterator test into the standard test because
the standard now specifies when the iterator should be available
[AArch64] - Allow for aggressive unrolling, with non-zero LoopMicroOpBufferSize for Oryon. (#172422)
Due to LoopMicroOpBufferSize being 0 value in Oryon machine model,
unrolling based on runtime TC was disabled. This is a pseudo value as
Oryon-1 does not have loop-uop buffer in it's micro-architecture. The
value 16 is empirical and inspired by machine model of cortex-a57 and
can be further tuned if required.
[SelectionDAG] Use SLEB128 for signed integers in isel table instead of 'signed rotated'. NFC (#173928)
Previously, we used a VBR that stored the sign bit in bit 0 followed by
the absolute value in subsequent bits.
This patch changes it to use SLEB128 which discards redundant sign bits,
but keeps the bits in the same positions. This uses the same number of
bytes to encode values so doesn't change the table size.
My goal is to remove OPC_EmitStringInteger as a special opcode type.
Instead, we can print the string directly with OPC_EmitInteger for any
string that has an enum value of 0..63.
plasma6-aurorae: add version 6.5.2
Aurorae is a themeable window decoration for KWin.
It supports theme files consisting of several SVG files for decoration and
buttons. Themes can be installed and selected directly in the configuration
module of KWin decorations.
[mlir][tensor] Preserve encoding in `CollapseShapeOp::build` (#173720)
This PR updates `CollapseShapeOp::build` so that when the result type is
not explicitly provided, the inferred result type preserves the encoding
of the source tensor.
plasma6-knighttime: add version 6.5.2
The `KNightTime` provides helpers for scheduling the dark-light cycle.
It can be used to implement features such as adjusting the screen color
temperature based on time of day, etc.
nfscl: Fix handling of POSIX draft default ACLs
A POSIX draft default ACL may not exist. As such,
an ACL with zero ACEs needs to be allowed.
This patch fixes acquisition of POSIX draft default
ACLs when they do not exist on the directory.
Fixes: a35bbd5d9f5f ("nfscommon: Add some support for POSIX draft ACLs")
fennel: update to 1.6.1
Packaging changes:
- fixed distfile issue
- man it possible to actually read the man page
- the manpage for the language itself is now fennel-lang.1 to avoid
conflict with pkgtools/pkg_alternatives's fennel.1
Upstream changes:
- Fix a bug where pattern matches on `...` could error out.

nfsd.8: Add a short paragraph w.r.t. NFSv3 vs NFSv4 setup
The nfsd can be configured to support NFSv3, NFSv4 or both
of them.
This patch adds a short paragraph to nfsd.8 to explain this.
This is a content change.
