[flang][debuginfo] Emit DW_AT_type for DW_TAG_string_type DIEs [3/3] (#231960)
Use the new DIStringType type field to emit the DW_AT_type attribute on
DW_TAG_string_type DIEs generated by Flang's debug type generator,
enabling debuggers to identify the character type of Fortran strings.

[libc][cmake] Unify unit and hermetic test rules into add_libc_test (#233512)
- Consolidate _add_libc_unittest and add_libc_hermetic into mode-aware
add_libc_test and create_libc_test rules using llvm_libc_parse_arguments
and forward_arguments (#232089), keeping add_libc_unittest,
add_libc_hermetic, and add_fp_unittest as thin forwarding wrappers.
- Replace separate libc-unit-tests and libc-hermetic-tests with unified
libc-tests and libc-tests-build targets.
- Introduce add_libc_testsuite to create both <suite> and <suite>-build
targets wired into libc-tests and libc-tests-build.
- Move add_fp_unittest into LLVMLibCTestRules.cmake via the FP_TEST
option and rename MPFR/MPC helper libraries to follow standard libc
target naming (libc.utils.MPCommon, libc.utils.MPFRWrapper,
libc.utils.MPCWrapper).
- Streamline _add_libc_test_runner: replace $<TARGET_FILE:...> with
configure-time binary paths, fast-path .params generation, and define
test runner targets directly via add_custom_target(... COMMAND ...
JOB_POOL ...) instead of intermediate .cmd stamp rules.
- Update docs and GPU benchmarks to use the unified test targets and

[libc++] Disable automatic module scanning on ARM CI builders (#232947)
The ARM Buildkite toolchains do not expose clang-scan-deps to CMake.
When CMP0155 enables automatic scanning for libc++abi C++23 sources,
these standalone runtimes builds fail with the scanner set to NOTFOUND.
Pass CMAKE_CXX_SCAN_FOR_MODULES=OFF in the eight ARM job invocations,
including the no-exceptions variants, until their toolchains provide a
matching scanner. Keep the other CI configurations on their defaults.

www/{nginx,nginx-devel,freenginx}: 3rd-party modules management
Build the auth_ldap module from its own source port, and add the
cert_expiry, ip_anon, stream limit_req and syslog5424 modules.
Sponsored by: Netzkommune GmbH
www/nginx-module-syslog5424: Add New Port
The syslog5424 module sends an access line in the format RFC 5424 asks for:
version, RFC 3339 timestamp, hostname, app name, process id, message id and
structured data.

www/nginx-module-stream-limit-req: Add New Port
The stream limit_req module rate limits incoming connections in the stream
subsystem. limit_req_zone and limit_req are spelled and counted as in the
http module, so a rate written down once reads the same for TCP, UDP and
HTTP.

www/nginx-module-auth-ldap: Add New Port
The auth_ldap module authenticates HTTP basic credentials against an LDAP
directory. An ldap_server block describes one directory, require rules say
who is let in, and every worker keeps a pool of connections to it.

www/nginx-module-ip-anon: Add New Port
The ip_anon module masks the host part of the client address.
$remote_addr_anon and $binary_remote_addr_anon carry the result, for a log
or a limit key that is not meant to name anybody.

www/nginx-module-cert-expiry: Add New Port
The cert_expiry module reads every file an ssl_certificate names, when the
configuration is read and again on a timer, and reports how long the
certificate still has. $ssl_expiry_days carries the days left into a log
format.

[clang][Modules] Disable module map subdirectory search by default (#234233)
cbd5ba20d1fa stopped searching the immediate subdirectories of header
search paths for module maps on Darwin using SDKs: macOS 15+, iOS 18+,

Now, disable it by default everywhere.
`-fmodulemap-allow-subdirectory-search` is kept as an opt-in for the
previous behavior.
[OpenACC] Handle device_type(*) properly for OpenACC routine bind (#234373)

`ACCMaterializeRoutineBindTargets`, and `ACCBindRoutine`.

"Updates for the VDSO subsystem:
- Ensure that the CLOCK_AUX base calculations are properly scaled
against the base timekeeper. The update function failed to take the
fractional nanosecond part into account, which results in a
rounding error.
- Cleanup and consolidate the vsyscall headers to get rid of
pointless copies all over the architectures.
- Replace a runtime conditional in the time getter function for
namespaced clocks by simple pointer arithmetic which speeds up the

[CIR][NFC] Avoid unused value for vtable address point (#234326)
We had been creating an unused value to emit a constant attribute for
vtable address points in ConstantRecordBuilder. We recently discovered
that the temporary operation wrapped by this value was being leaked. A
quick fix was added to delete the operation. This change applies the
more thorough fix of just creating the attribute directly without
creating a temporary value.

Pull timer core updates from Thomas Gleixner:
"Updates for the core timekeeping and timers subsystem:
- Futher cleanups for the POSIX timer exit/exec related code to
simplify the code flow and to make it more robust against future

- Prevent tearing of timekeeper::ktime_sec which can be accessed
without the sequence count protection.
The timekeeper is updated by memcpy() with an uneven sequence count
to force readers into the retry path. On 64-bit machine the
ktime_sec member can be accessed atomically without the sequence
count protection. That is only correct when the update side
memcpy() guarantees atomicity at the 64-bit granularity. That's not
guaranteed due to debug options, compilers and instruction
availability. If the memcpy() does not provide the atomicity then

[libc][cmake] Respect the configured optimization level for the Linux thread and TLS objects
The -O3 override on the Linux thread object dates from the old approach of
reading the thread arguments off the new thread's stack, which #225384
removed; the TLS objects copied the same pattern in #225418. Neither needs
it anymore, so drop the overrides and use the optimization level configured
by CMake.

"Updates for interrupt chip drivers:
- Remove the futile attempts to cleanup resources when the probing of
the main interrupt chip fails for SiFIVE/PLIC devices. If that
probe fails the system will stall immediately afterwards in the

diagnosed. The lack of resource cleanup led to a frenzy of AI
detected/assisted "fixes" which just make the code pretend to be

Remove the existing half baked cleanup and immediately panic the

it proceed and stall out a millisecond later with no information
about the root cause.

CodeGen: Stop using LiveVariables in tests (#234293)
Change most of these tests to use live-intervals instead, assuming
there's some value in testing whatever edge case once broke live
variables. Some cases seem to use it just to drive other passes where
it makes sense to just slot it in. The one case that seems
unrecoverably useless is a test for the extra implicit def operands
LiveVariables would add involving subregister defs.
