As explained in https://gitlab.kitware.com/cmake/cmake/-/issues/21045,
both branches of an $<IF> generator expression are evaluated eagerly
by CMake. As a result, if the non-selected branch contains an invalid
generator expression (such as getting the OUTPUT_NAME property of a
non-existent target), a hard error will occur.
This failed builds using the cxxrt ABI library, which doesn't create
a CMake target currently.
This change allow CooperativeMatrix Load/Store operations to use pointer type
that may not match the matrix element type. This allow us to declare buffer
with a larger type size than the matrix element type. This follows SPIR-V spec
and this is needed to be able to use cooperative matrix in combination with
shared local memory efficiently.

* If no input files are given, f18 reads from stdin
* If no input files are given, f18 dumps the parse tree.
* The default behaviour is to exec F18_FC.
* The fefault F18_FC setting is 'gfortran'

In a context in which `shape.broadcast` is known not to produce an error value,
we want it to operate solely on extent tensors. The operation's behavior is
then undefined in the error case as the result type cannot hold this value.

DR2303 fixes the case where the derived-base match for template
deduction is ambiguous if a base-of-base ALSO matches. The canonical
example (as shown in the test) is just like the MSVC implementation of
std::tuple.
This fixes a fairly sizable issue, where if a user inherits from
std::tuple on Windows (with the MS STL), they cannot use that type to
call a function that takes std::tuple.

Since weak is meaningless for a shared library interface function, this patch
disables the attribute, when the OpenMP library is built as shared library.
ompt_start_tool is not an interface function, but a internally called function
possibly implemented by an OMPT tool.
This function needs to be weak if possible to allow overwriting ompt_start_tool

I'm substituting that `#include` with the public one by moving the necessary

We can preserve make.implicit metadata in the split block if it is
guaranteed that after following the branch we always reach the block
where processing of null case happens, which is equivalent to
"initial condition must execute if the loop is entered".

Non-trivial unswitching simply moves terminator being unswitch from the loop
up to the switch block. It also preserves all metadata that was there. It might not
be a correct thing to do for `make.implicit` metadata. Consider case:
```
for (...) {
cond = // computed in loop
if (cond) return X;
if (p == null) throw_npe(); !make implicit
}
```
Before the unswitching, if `p` is null and we reach this check, we are guaranteed
to go to `throw_npe()` block. Now we unswitch on `p == null` condition:
```
if (p == null) !make implicit {
for (...) {
if (cond) return X;
throw_npe()
}
} else {
for (...) {
if (cond) return X;
}
}
```
Now, following `true` branch of `p == null` does not always lead us to
`throw_npe()` because the loop has side exit. Now, if we run ImplicitNullCheck
pass on this code, it may end up making the unswitch condition implicit. This may
lead us to turning normal path to `return X` into signal-throwing path, which is
not efficient.
Note that this does not happen during trivial unswitch: it guarantees that we do not
have side exits before condition being unswitched.
This patch fixes this situation by unconditional dropping of `make.implicit` metadata
when we perform non-trivial unswitch. We could preserve it if we could prove that the
condition always executes. This can be done as a follow-up.

On an iOS device, if debugserver is left to figure out how to launch
the binary provided, it looks at the filename to see if it contains
".app" and asks FrontBoard to launch it. However, if this is actually
a command line app with the characters ".app" in the name, it would
end up trying to launch that via the FrontBoard calls even though it
needed to be launched via posix_spawn. For instance, a command line
program called com.application.tester.
Jim suggested this patch where we only send binaries that end in ".app"
to FrontBoard.
Often debugsever is invoked with a --launch command line argument to
specify the launch method, and none of this code is hit in that
instance.

I fixed an assert caused by passing an empty array as the source= argument to
RESHAPE(). In the process, I noticed that there were no tests for RESHAPE(),
so I wrote a test that covers all the description in 16.9.163. In the process,
I made the error messages more consistent and descriptive. I also changed the
test to see if a reference to an intrinsic function was a constant to say that
it is a constant if it's a refererence to an invalid intrinsic. This avoids
emitting multiple messages for the same erroneous source.
