[flang][cuda] Accept cuf kernel do without scalar (#205705)
The base compiler accept `!$cuf kernel do()` instead of raising an
error. Update the parser to accept the same syntax.
`!$cuf kernel do()` is equivalent to `!$cuf kernel do`
[AArch64] Add missing SubtargetFeature for hip12 core (#205246)
The initial patch for the hip12 core had omitted several subtarget
features:
FeatureFP16FML, FeatureFlagM, FeaturePredRes, FeatureSB, FeatureSSBS,
FeatureCCIDX, FeatureRandGen.
ld.elf_so(1): Run concurrent dlopen/dlclose test a few more seconds.
More likely to provoke the problem this way. Still not 100% reliable
because the problem is a race condition, but better than having the
test unexpectedly pass half the time.
Also set a timeout of 20sec, since I've seen the test get into an
infinite loop sometimes and it's now supposed to complete in 5sec +
epsilon.

[SampleProfileMatcher] Sample profile duplication to avoid stale CFG profile matching conflicts (#202460)
Stale profile matching may map multiple different IR anchors into one
profile anchor because of the common function basename. One example is
`foo(int)` and `foo<bar>(float)` can both be mapped to `foo()` if
`foo()` is the only function that has a profile. And this creates
conflicting CFG matching for `foo(int)` and `foo<bar>(float)` when they
each runs stale profile matching. The CFG matching results will be
overwritten among the conflicting functions. And it will trigger the
following assertation failure:
https://github.com/llvm/llvm-project/blob/7087094b05a1bba64a99474cc501328919e11b4a/llvm/lib/Transforms/IPO/SampleProfileMatcher.cpp#L332-L333
This patch tries to detect this conflict during the stale CG matching,
and create duplicated profiles to avoid CFG matching conflicts.
Fix ProcessElfCore::FindModuleUUID() so it work with symlinks. (#205235)
ProcessElfCore was reading the NT_FILE list and using that to help
FindModuleUUID to provide UUID information when loading core files. The
NT_FILE list contains resolved paths only, while the
DynamicLoaderPOSIXDYLD plug-in was using paths found in the r_debug
structure which contains a linked list of all of the shared libraries in
a process. The issue was these paths could be symlinks which would cause
ProcessELFCore::FindModuleUUID(...) to fail because the paths wouldn't
match up. This led to the ProcessELFCore often not being able to provide
UUIDs for shared libraries and cause the incorrect binaries to be loaded
from the current machine even when the shared library UUIDs don't match.
The solution was to add the ability for a ModuleSpec to contain a load
address for the shared library. This allows ProcessELFCore to uniquely
identify a library regardless of the name used in NT_FILE. We can now
correctly supply the UUID from the .gnu-build-id to any binaries which
use symlinks when linking, but have differing resolved paths to the
libraries.

jail: clean up locking around do_jail_attach
jail_attach_jd passed PD_DEREF to do_jail_attach, assuming it would take
care of freeing the held prison. This is not true, as do_jail_attach
immediately cleared that flag, leaving the jail stock in dying state
when it is later removed.

kern: osd: trash a slot's methods upon deregistration
This both lets us quickly identify a slot that's been deallocated while
debugging, and forces us to take a fault if something tries to call one

[Clang] Transform SubstNonTypeTemplateParmExpr replacements in a constant-evaluated context (#196791)
Fixes #175831.
When transforming a `SubstNonTypeTemplateParmExpr`,
`TreeTransform::TransformSubstNonTypeTemplateParmExpr` calls
`Sema::CheckTemplateArgument` so that any sema annotations (such as
implicit casts) that were stripped from the replacement are recovered.
This is done in whatever evaluation context the node happens to appear
in after substitutions.
Since the normalization of constraints, a `SubstNonTypeTemplateParmExpr`
can end up inside an unevaluated operand, so the replacement gets
rebuilt in an unevaluated context.
Entities it refers to are then not odr-used: for example, when a call
materializes a by-value function parameter of class type, the copy
constructor is never marked odr-used and its definition is never
instantiated.
