[Instrumentor] Add runtime examples: [2/N] A FP precision analysis
Second example:
Check all floating point operations and track if they could be done at
lower precision.
Partially developped by Claude (AI), tested and verified by me.
write: some small cleanup
- pledge on start, restricting to stdio later on
- annotate done as __dead and remove unreachable return in main
- use common code to remove the /dev/ prefix from a device name
- wrap the PUTC macro into do {} while (0) to avoid extra empty statement
- use strftime() instead of using an offset into the ctime() string
- pass ttyl as size_t not int in search_utmp() to match the variable

[Instrumentor] Add runtime examples: [1/N] A flop counter
This adds a instrumentor-tools folder into compiler RT to showcase
use cases of the instrumentor. The initial example is a program that,
via instrumentation, counts the number of flops performed. Call and
intrinsic support will follow after #198042.

[llubi] Add basic support for pointer comparisons (#205410)
This patch was a part of
https://github.com/llvm/llvm-project/pull/201170. I split the `icmp ptr`
support from the original PR since I am worried it might not catch up
for the LLVM 23 release (#201170 is blocked by #200672 for curating
mixed provenance tests). I hope we can pick most of the low-hanging
fruit exposed by fuzzers before the release. The released version should
be able to run csmith-generated tests without obvious false positives or
crashes.
BTW, this patch doesn't respect the exact semantics of `icmp ptr` (i.e.,
truncating the address to the address width. The naming is a bit
confusing...). Currently, we don't model external state in non-address
bits of a pointer in llubi. So I think it is fine.

[Instrumentor] Add subtype IDs to complement type IDs for vectors/arrays
If the type of an argument passed to the instrumentation is a vector or
array, we still want to filter on the underlying type, and the
instrumentation might also need to know. Thus, we can now pass a subtype
ID, which is -1 except if it's a vector or array, then it's the element
type ID. Structs need to be handled differently.
[mlir] Simplify DimOp::fold by using `getConstantIndex`(NFC) (#205343)

net/rsync: drop py-cmarkgfm build dep, fix inert path substitutions
Drop python and py-cmarkgfm from the BUILD_DEPENDS: The tarball ships
pre-rendered nroff man pages, so the upstream md2man toolchain is not needed.
While here, fix a post-patch REINPLACE_CMD pattern that has been silently
inert since 2022 (PR 263787): Replace with two correct substitutions so the
installed man pages reference ${ETCDIR} instead of /etc/rsync*.
Bump PORTREVISION because installed man page content changes.

Merge tag 'f2fs-for-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"The changes primarily focus on filesystem error reporting, reducing
memory footprint by reverting in-memory data structures used for
runtime validation, honoring FDP hints, and adding trace and debug
logs. In addition, there are critical bug fixes resolving
out-of-bounds read vulnerabilities in inline directory and ACL
handling, potential deadlocks in balance_fs, use-after-free issues in
atomic writes, and false data/node type assignments in large sections.
Enhancements:
- Revert in-memory sit version and block bitmaps
- support to report fserror
- add trace_f2fs_fault_report
- add iostat latency tracking for direct IO
- add logs in f2fs_disable_checkpoint()
- honor per-I/O write streams for direct writes
- map data writes to FDP streams

[C++ Safe Buffers][libcxx][test] Add a test for hardened span in ObjC++
The C++ Safe Buffers project does not officially support ObjC++, while
people may still want to apply the analysis to ObjC++ code for
improved confidence. However, it would be meaningless to do so if
hardened containers do not trap out-of-bounds accesses. We need to add
a test that shows that hardened containers do work for ObjC++.

[flang][OpenMP] Fix ICE lowering user-defined operator declare reduction
A REDUCTION clause naming a user-defined operator (e.g.,
reduction(.myop.:x)) crashed in lowering: ReductionProcessor assumed the
DefinedOperator clause variant always held an intrinsic operator and called
std::get<IntrinsicOperator> unconditionally, which aborts for the
DefinedOpName alternative.
Handle DefinedOpName in the reduction clause processor, adding the
clause-side counterpart to the directive handling from #190288. For a
locally declared user-defined operator reduction, resolve the operator to
its reduction symbol and reference the omp.declare_reduction op materialized
for the declare reduction directive. The op name is now module-scoped via
AbstractConverter::mangleName, on the directive and clause sides in
lockstep, so reductions with the same operator spelling in different modules
no longer collide.
Cases that are not yet supported (reductions imported by USE association,
renamed or merged operators, and declarations with multiple types) now emit
