Update former maintainers (#229276)
b2ff0e8eae8236e7555afa6026e0cf251af8c4ae updated the
OpenMPOpt/Attributor maintainers but did not add Johannes to the former
maintainers list.
[InstCombine] Fix ProfCheck for canonicalizeClampLike (#229269)
We cannot know the profile in the general case (see the added comment),
so mark the selects unknown for now. In the case that C2 is at one of
the bounds we can, but I expect this case is rare enough that handling
it explicitly doesn't make much sense.

[flang][cuda] Reject implicit transfer of assumed-size device arrays (#229128)
An assignment in host code whose right-hand side mixes device data with
host data or constants is lowered as an implicit data transfer: each
device object is copied whole to a host temporary created from its mold,
and the expression is evaluated on the host. The size of an assumed-size
array (an assumed-size dummy or a Cray pointee declared with `(*)`) is
unknown, so the temporary cannot be created and lowering crashed with an
invalid fir.convert:
double precision :: a(*)
pointer (ip, a)
attributes(device) :: a
h = h + a(3)*2.0d0
Report a semantic error instead when such an assignment references an
assumed-size device array. Assignments that do not need an implicit
transfer are still accepted: element transfers like `h = a(3)` and
host-to-device assignments like `a(3) = h*2.0d0`.
This align flang with the reference compiler.
[lldb] Unload Wasm modules the stub no longer reports (#227814)
When a Wasm engine such as JavaScriptCore reloads a page, the modules it
ran go away and new instances take their place. LLDB kept two kinds of
stale module around.
ProcessGDBRemote::LoadModules never unloads the target's executable,
which no library list includes. A Wasm target has no executable, so
Target::GetExecutableModule falls back to the first module, and the
first module the stub ever reported stayed in the image list for good.
Let the dynamic loader say whether the process runs a main executable,
and have the Wasm loader say it does not.
A module reloaded under the same name matched the module read from
memory at its old address, and LLDB then moved that module to the new
one. That trips an assertion in ObjectFileWasm::SetLoadAddress, and
otherwise leaves a module whose image came from an instance that is
gone. A module read from memory now only matches a spec at the address
it was read from, like ModuleSpec::Matches already does for two specs.

fixup! [AMDGPU] Measure MFMA read hazards at each producer
Turn the walk into a small class, WindowDeficitSearch, with its state as
members, and count wait states through one helper that states the
inline asm assumption.

devel/guile-lib: Change to guile30 instead of guile22
The only users in pkgsrc+wip are:
wip/g-golf, which is maintained and wants 3.0
devel/g-golf, which is not maintained and wants 2.0 (not 2.2!)
My belief is that there are zero people that are using guile-lib from
pkgsrc with guile 2.2; if so we should probably version it.
[AMDGPU] Fix missed WMMA C-operand co-exec hazard
The gfx1250 WMMA co-execution hazard check treats only A, B and the
SWMMAC index as registers the in-flight MMA still reads. C (src2 of a
non-SWMMAC WMMA) is missing, so a VALU scheduled into the MMA's shadow
can clobber C and the MMA consumes the new value.
This is latent while C is tied to vdst, since the existing D check then
covers it. It miscompiles where the tie does not hold: for
v_wmma_bf16f32_16x16x32_bf16, whose D is narrower than C, and for the
_threeaddr form of any WMMA.
scapy: Fix send() and friends for NetBSD, bump revision
Scapy assumes that PF_ROUTE is 17 like on other *BSD systems.
However, for NetBSD, PF_ROUTE has been 34 since 6.0 release.
[NFC][lsan] Disable HWASan on key_destructor in detached_thread_dlsym.c (#229266)
Test-only change fixing the test added in
https://github.com/llvm/llvm-project/pull/228930.
In `detached_thread_dlsym.c`, `key_destructor` intentionally runs on the
final (`PTHREAD_DESTRUCTOR_ITERATIONS`) TSD destruction pass after
`HwasanTSDDtor` has called `Thread::Destroy()` and zeroed
`__hwasan_tls`.
Mark `key_destructor` with `__attribute__((no_sanitize("hwaddress")))`.
Fixes https://lab.llvm.org/buildbot/#/builders/51/builds/45276.

[flang][acc] Preserve association status of privatized pointers (#228581)
Privatization allocated a target and copied it even when a Fortran
pointer or allocatable was unassociated or unallocated. That reads
through a null address. The private allocation now follows the original
association status. A reduction stores its initial value only when that
storage exists. The target is copied only when one exists.
Before:
```
%private = fir.allocmem f32
// Box %private into the private descriptor.
hlfir.assign %src to %private temporary_lhs : f32, !fir.heap<f32>
```
After:
```
%private = fir.if %is_associated -> !fir.heap<f32> {
%allocation = fir.allocmem f32

[mlir] Migrate AMDGPU/ROCDL to targets, not chipset versions
**migration tl;dr:** Replace usages of `amdgpu::Chipset` with `ROCDL::TargetInfo`, ideally move from `chipset=` to `arch=`. If you don't use upstream pipelines, call 'TargetInfo::migrateArchFeaturesToModuleFlags` at the appropriate location.
Further note: if you've got a build pipeline that's getting a `gfxXXX` name from something like `rocm_agent_enumerator`, using a full triple name like the ones you get from `rocminfo` is preferred.
`amdgpu::Chipset` was an awkward hack that was hard to keep up to date
with changes in the compiler/new architectures, and didn't properly
support generic targets (and has been strongly disfavored by the
compiler team).
This PR replaces `amdgpu::Chipset` with `ROCDL::TargetInfo`, a
structure that uses LLVM's TargetParser and the underlying LLVM
features tables to get the real nature of the target being compiled
for.
This also helps MLIR move to
new-style (`-mtriple=amdgpuX.YZ-amd-amdhsa`) over "old
style" (`-mtriple=amdgcn-amd-amdhsa -mcpu=gfxXYZ`) triples.
