There is some exotic conditional logic here to avoid building a
particular test if a certain UBSAN library isn't present in the
toolchain sysroot. This causes build failures for me when doing an
"installworld WITHOUT_TOOLCHAIN=", which I do frequently during tests.
I believe the problem is that SYSROOT is unset during installworld, so
the build sees the host's copy of libclang_rt.ubsan_standalone.a and
then tries to install a binary that wasn't built during buildworld. Try
to make the check a bit less fragile.

This patch introduces the RoCE driver for the
Broadcom NetXtreme-E 10/25/50/100/200G RoCE HCAs.
The RoCE driver is a two part driver that relies
on the bnxt_en NIC driver to operate. The changes
needed in the bnxt_en driver is included through
another patch "L2-RoCE driver communication interface"
in this set.
Presently, There is no user space support, Hence
recommendation to use the krping kernel module for
testing. User space support will be incorporated in
subsequent patch submissions.

Implement firmware error recovery support for Thor adapters.
This entails enabling the capability for the firmware to initiate
error recovery. Specifically, the firmware will send the reset notify
asynchronous event to notify the driver of an error and impending reset.
Subsequently, the driver will queue a task to execute the following steps.
1. Deactivate the allocated resources.
2. Await completion of the firmware's recovery process.
3. Configure the resources and reactivate the network interface.

... or install an empty file.
The locate database is a mutable working file, and unsuitable to be
managed by pkg(8). locate(1) copes gracefully with the absence of
this file. Running /etc/periodic/weekly/310.locate will create the
locate database with the correct ownership and permissions.
Having the locate.database file as part of the FreeBSD-runtime package
means it gets zeroed if ever that package gets updated, which is
excessive, given that updating packages will typically only change a
relatively small number of the _filenames_ on the system -- unlike the
file contents. Plus it always causes it to flag as modified when
verifying checksums, but /var/db/locate.database is expected to be

[X86] Add slow div64 tuning flag to Nehalem target (#91129)
This appears to have been missed because later cpus don't inherit from Nehalem tuning much.
Noticed while cleaning up for #90985
Merge commit 8b400de79eff from llvm-project (by Simon Pilgrim):
[X86] Enable TuningSlowDivide64 on Barcelona/Bobcat/Bulldozer/Ryzen Families (#91277)
Despite most AMD cpus having a lower latency for i64 divisions that converge early, we are still better off testing for values representable as i32 and performing a i32 division if possible.
All AMD cpus appear to have been missed when we added the "idivq-to-divl" attribute - this patch now matches Intel cpu behaviour (and the x86-64/v2/3/4 levels).
Unfortunately the difference in code scheduling means I've had to stop using the update_llc_test_checks script and just use old-fashioned CHECK-DAG checks for divl/divq pairs.
Fixes#90985
This fixes possibly worse runtime performance on AMD Zen hardware, when
using -march=znver4 (or any other znver), as opposed to -march=x86-64-v4
or the baseline -march=x86-64. A similar fix is applied for Nehalem.
