[AMDGPU] SIFoldOperands: constant-fold S_ADD/S_SUB with immediate operands (#198410)
Extend SIFoldOperands::tryConstantFoldOp to recognise three patterns
* ADD/SUB(imm, imm) -> S_MOV_B32 (LHS +/- RHS)
* ADD x, 0 -> COPY x (Also `0 + x`)
* SUB x, 0 -> COPY x (SUB is not commutable)

[X86] Fold splat AND on VGF2P8AFFINEQB source (#193364)
Given that each row within `vgf2p8affineqb`'s matrix controls which
source bits are selected, zeroing the same bit within all rows treats
that corresponding source bit like it is zero. This means a AND of the
input by any splatted 8-bit values can be folded with the matrix. This
is patch:
- Can eliminate a constant and/or reduces the instruction count from 2
to 1.
- Only occurs when the matrix is constant, ensuring that it can't
increase the dependency chain.
- Don't occur if the AND is multi use well the splat isn't constant,
preventing additional operations.
- Work with both constant 8-bit splats and scalars value that where
splatted to a vector.
- Includes test coverage for positive cases (by constants, variable
scalars, non zero immediates) and negative (multi use, larger splats,
variable matrices).
Fixes #191325
[libc] prefer *at syscalls in sys/stat wrappers (#197940)
- These changes flips the #ifdef order to prefer the *at syscalls over
normal ones.
- In modern architectures, *at system calls are preferred over normal
system calls cuz of safety issues.
- So by checking for ""*at"" system calls first, we ensure better
compatibility with modern systems.
- After then normal syscalls moved else or elif for support to older
ones.
- From merged pr(#195792) and issue(#195620)

[X86] Lower vector i8 ashr-by-1 using pavgb (#198487)
For vector i8 arithmetic shift right by 1, the current lowering produces
a 5-instruction sequence (psrlw + pand + xor + psubb plus a constant
load) with a 4-deep dependency chain.
This patch uses the identity
ashr(x, 1) == avgceilu(x, -1) ^ (~x & 0x80)
to lower to ISD::AVGCEILU + a short fixup, producing 4 instructions on
SSE/AVX/AVX2 and 3 on AVX-512BW (after vpternlogd fusion of the AND/XOR
pair), with two parallel dependency chains instead of one long one.
The freeze on R is required because the target reads it twice, matching
the pattern of the existing `shl R, 1 -> add R, R` case in
LowerShiftByScalarImmediate.

[flang][OpenMP] Skip declare simd lowering for interface bodies (#197010)
When DECLARE SIMD appears in the specification part of an interface
body, the PFT records the directive as an evaluation of the enclosing
program unit rather than of the interface body's subprogram. Its clause
operands (linear/aligned/uniform) reference dummy arguments local to the
interface body, which have no address in the enclosing scope, causing a
crash.
Detect the mismatch by comparing the program unit containing the
directive with the procedure currently being lowered, and skip op
emission when they differ.
This handles both explicit declare simd(proc-name) and implicit forms in
any enclosing context.
Fixes #192581

[LLVM] Add a function to reset the opt bisector (#197723)
For daemonized testing, we need to be able to reset the global opt
bisector between test runs. This PR just adds a small function to the
OptPassGate class to reset its state.

[Flang] Adding -ffree-line-length-<value> flag (#192941)
Added support for the `-ffree-line-length-<value>` flag in Flang, which
is equivalent to `-ffixed-line-length-<value>` but in free form.
This flag is supported by gfortran and can be used in some applications.

[Clang] [NFC] Use `unique_ptr<Lexer>` everywhere (#198393)
Replace every instance of `new Lexer` with `make_unique<Lexer>` and
adjust `Lexer::Create_PragmaLexer()` to return a `std::unique_ptr<Lexer>`
instead.
The Preprocessor was already storing a `unique_ptr<Lexer>`, so there’s
no need to change how that works.
Restrict on-disk perms of internal container/apps dataset roots
The internal dataset trees that back containers
(/mnt/.truenas_containers/), Docker apps (/mnt/.ix-apps/), and the
per-container idmapped bind-mount parent (/run/truenas_containers/root/)
are implementation-detail paths that aren't intended to be inspected
directly by host users. They currently mount with the default of
drwxr-xr-x root:root (or 0755 from os.makedirs for the /run parent),
which is looser than necessary.
This PR pins those three directories to 0700 root:root and re-applies
the mode at the relevant entry points so the property is idempotent
across reboots and manual chmod drift.

[DAG] scalarizeExtractedBinOp - extract from non-constant one use buildvectors (#198013)
When attempting to scalarize a vector binop that has a single extract,
we currently only fold if either of the binop's operands is a constant
buildvector - but we can extract from non-constant buildvectors without
increasing instruction count as long as the vector binop was the only
use of the buildvector.

[flang][acc] Handle Fortran do loops as acc loops in acc routine (#198420)
As was previously done for do loops in acc compute constructs in
https://github.com/llvm/llvm-project/issues/149614 , this PR does the
same for do loops in `acc routine`. The rules are follows:
- Do loops not marked with `acc loop` are considered `auto`
- Do concurrent loops are considered `independent`
- Any loops in an `acc routine seq` are considered `seq`
This ensures that the IV is correctly privatized and attached to acc
loop.
kitty: update to 0.47.0
- A new Drag and drop kitten to allow drag and drop of files from
your shell to any GUI program even across SSH
- A new option palette_generate to automatically generate the 256
color palette from the first 16 colors
- For builtin key mappings automatically fallback to matching the
US-PC layout key when the pressed key has no matches and is a
non-English character
- Allow drag and drop of windows to re-arrange them, move them to
another tab/OS Window or detach them into a new OS Window. See
toggle_window_title_bars to temporarily show window title bars to
drag them around
- Have scroll_line_up and scroll_line_down smooth scroll by default.
Can be restored to old behavior by re-mapping without the smooth
argument
- Draw a progress bar at the top of the window when a program
reports progress using the OSC 9;4 escape sequence, controlled by
progress_bar

net: bandaid for plugging a fw_com leak in fwip_detach()
Adding a temporary workaround for plugging a fw_com upon if_fwip unloading.
Steps to reproduce(needs two hosts connected with firewire):
while true; do
ifconfig fwip0 10.0.0.5 up
fwcontrol -r
ping -c 10.0.0.3
kldunload if_fwip
done
There's a chance that the unloading of if_fwip.ko triggers following warning:
Warning: memory type fw_com leaked memory on destroy (1 allocations, 64 bytes leaked).
