[ConstraintElim] Re-organize tests with decomposition failures (NFC). (#212130)
Add more tests for failed decomposition, consolidate them in
partial-decomposition.ll.
[mlir][arith] Fold trivial integer division and remainder (#212074)
Add value-preserving folds mirroring LLVM's InstructionSimplify for the
integer division and remainder ops:
```
divui/divsi/ceildivui/ceildivsi/floordivsi(0, x) -> 0
divui/divsi/ceildivui/ceildivsi/floordivsi(x, x) -> 1
remui/remsi(0, x) -> 0
remui/remsi(x, x) -> 0
```
The self and zero-dividend cases are valid refinements because division
or remainder by zero is undefined behaviour; no overflow flags are
required. The folds return a scalar or splat constant and bail out on
shaped types with a dynamic shape.
Folding `x / 0` and `x % 0` to poison is left as a TODO: it would make
the arith dialect depend on the ub dialect to materialize `ub.poison`.

math/openblas: fix build on i386
Due to a miscompilation, a stack variable accessed by the MOVAPS
instruction ends up being misaligned. With MOVAPS requiring memory
operands to be aligned, this causes a bus error on i386. The underlying
cause could be that gfortran assumes a 16-byte aligned stack as is the
case on current i386 Linux, while we have not done the same ABI change.
I have worked around the problem by passing -mpreferred-stack-boundary=2
to disable assumptions about stack alignment, though ultimately this
will need to be fixed in the gcc and gfortran ports.

[libc++][chrono] Implement LWG 4274: Allow chrono::hh_mm_ss to be constructed from unsigned durations (#209686)
**_Implementation details_**:
- Use `is_unsigned_v` instead of `numeric_limits<Rep>::is_signed`, which
is used by `chrono::abs`. `numeric_limits<Rep>::is_signed` may return
false when a custom `Rep` does not specialize `numeric_limits`. Relying
on it to detect the unsigned case could therefore be unreliable for such
a type. `is_unsigned_v` instead gives a compile-time path for built-in
unsigned types, while the sign check keeps signed types correct.
- The constructor calls `__abs_d` four times because each member is
initialized separately. This should not affect runtime performance
because the compiler should inline `__abs_d` and eliminate the repeated
calculations. We could use another helper function or helper class to
explicitly compute the absolute duration only once. However, this would
add extra glue code, and the added complexity is not worthwhile I think.

devel/matreshka: Sync with main; improve Port
Update and improve:
* Drop un-testable Oracle DB support
* Patch build to increase verbosity
* Patch and modify the Port to reduce update burden with ${PLIST_SUB}
support, and abstracting the shared object, and GNAT runtime
version information in pkg-plist
* Remove all hard-coded version information, freeing the library
from the current restriction of GNAT-12
* Set ${MAINTAINER} to ada at FreeBSD.org.
* Sync with Upstream main

games/OpenLoco: Open source re-implementation of Chris Sawyer's Locomotion
OpenLoco is an open-source re-implementation of Chris Sawyer's
Locomotion (CSL), the spiritual successor to Transport Tycoon. OpenLoco
aims to improve the game similar to how OpenTTD improved Transport
Tycoon, and OpenRCT2 improved RollerCoaster Tycoon.
CSL was originally written in x86 assembly, building on top of the
RollerCoaster Tycoon 2 engine. However, the engine has changed
substantially enough that OpenLoco currently does not share its codebase
with OpenRCT2.
As of December 2025, we have completed reimplementing the game in C++.
It is now our goal to get a solid multiplayer experience working in
OpenLoco. It is also our goal to increase the map and vehicle limits.
However, until creating a new save format (NSF), we are bound to the
limits imposed by the CSL save format (SV5/SC5).

emulators/fab-agon-emulator: clean up, fix on 16-CURRENT
- CARGO_CARGO_RUN includes cd ${WRKSRC}, and running it under
SETENVI means that /usr/bin/cd was executed, which clearly
didn't do any good.
- remove double dependency on sdl3
- spell product name right in COMMENT
- reflow to 80 columns

devel/sfl-library: C++ datastructure library
This is a header-only C++11 library that provides several new or
lesser-known containers, most of which can be used in C++20 constant
expressions.
Sequence containers: vector, devector, small_vector, static_vector,
compact_vector, segmented_vector, segmented_devector.
Associative containers based on red-black trees: map, set, multimap,
multiset, small_map, small_set, small_multimap, small_multiset,
static_map, static_set, static_multimap, static_multiset.
Unordered associative containers based on hash tables with separate
chaining: unordered_map, unordered_set, unordered_multimap,
unordered_multiset, small_unordered_map, small_unordered_set
small_unordered_multimap, small_unordered_multiset,
static_unordered_map, static_unordered_set, static_unordered_multimap,
static_unordered_multiset.
