Previously, some semantic checks that are checking if an entity is an
allocatable were relying on the expression being a designator whose
last symbol has the allocatable attribute.
This is wrong since this was considering substrings and array sections of
allocatables as being allocatable. This is wrong (see NOTE 2 in
Fortran 2018 section 9.5.3.1).
Add evaluate::IsAllocatableDesignator to correctly test this.
Also add some semantic tests for ALLOCATED to test the newly added helper.
Note that ifort and nag are rejecting coindexed-named-object in
ALLOCATED (`allocated(coarray_scalar_alloc[2])`).
I think it is wrong given allocated argument is intent(in) as per
16.2.1 point 3.
So 15.5.2.6 point 4 regarding allocatable dummy is not violated (If the actual
argument is a coindexed object, the dummy argument shall have the INTENT (IN)
attribute.) and I think this is valid. gfortran accepts it.
The need for this helper was exposed in https://reviews.llvm.org/D122779.

Statically checking for overflow with
if constexpr (sizeof(std::size_t) <= sizeof(std::int64_t)) {
return static_cast<std::int64_t>(length);

Doesn't work if `sizeof(std::size_t) == sizeof(std::int64_t)` because std::size_t
is unsigned.
if `length == std::numeric_limits<size_t>` casting it to `int64_t` is going to overflow.

When folding MAXLOC/MINLOC, the current element being compared was moved twice
in row in case it became the new extremum. With numeric and logical types, it
made no difference (std::move is a no-op for them), but for characters
where the string storage is actually moved, it caused the new extremum to
be set to the empty string, leading to wrong results.
Note: I could have left the first std::move relating to logical Findloc, but it
brings nothing and makes the code less auditable, so I also removed it.

Adds flang/include/flang/Common/visit.h, which defines
a Fortran::common::visit() template function that is a drop-in
replacement for std::visit(). Modifies most use sites in
the front-end and runtime to use common::visit().
The C++ standard mandates that std::visit() have O(1) execution
time, which forces implementations to build dispatch tables.
This new common::visit() is O(log2 N) in the number of alternatives
in a variant<>, but that N tends to be small and so this change
produces a fairly significant improvement in compiler build
memory requirements, a 5-10% improvement in compiler build time,
and a small improvement in compiler execution time.
Building with -DFLANG_USE_STD_VISIT causes common::visit()
to be an alias for std::visit().
Calls to common::visit() with multiple variant arguments
are referred to std::visit(), pending further work.

Follow up of https://reviews.llvm.org/D121488. Ensure lower bounds

bounds from descriptors are now guaranteed to fulfill this property
after the runtime/codegen patches.
Also fixes explicit shape array extent lowering when instantiating
variables to deal with negative extent cases (issue found while testing
LBOUND edge case). This notably caused allocation crashes when dealing
with automatic arrays with reversed bounds or negative size
specification expression. The standard specifies that the extent of such
arrays is zero. This change has some ripple effect in the current lit
tests.
Add move two helpers as part of this change:
- Add a helper to tell if a fir::ExtendedValue describes an assumed size

time and runtime).
- Move and share getIntIfConstant from Character.cpp so that it can be

This caused `print *,lbound(x,kind=8)` to unparse as `print*,lbound(x)` which is not

In FIR, we want to wrap function pointers in a special box known as a
boxproc value. Fortran has a limited form of dynamic scoping
[https://tinyurl.com/2p8v2hw7] between "host procedures" and "internal
procedures". There are a number of implementations possible.
Boxproc typed values abstract away the implementation details of when a
function pointer can be passed directly (as a raw address) and when a
function pointer has to account for the presence of a dynamic scope.
When lowering Fortran syntax to FIR, all function pointers are emboxed
as boxproc values.
When creating LLVM IR, we must strip away the abstraction and produce
low-level LLVM "assembly" code. This patch implements that
transformation as converting the boxproc values to either raw function
pointers or executable trampolines on the stack as needed. The
trampoline then captures the dynamic scope context within an executable
thunk that can be passed instead of the function's raw address.
Some extra handling is required for Fortran functions that return a
character value to deal with LEN values here.

faciliate the upstreaming effort.

Some refactoring and related fixes for more accurate
user program error recovery in the I/O runtime, especially
for error recovery with IOMSG= character values.
1) Move any work in an EndIoStatement() implementation
that may raise an error into a new CompleteOperation()
member function. This allows error handling APIs like
GetIoMsg() to complete a pending I/O statement and harvest
any errors that may result.
2) Move the pending error code from ErroneousIoStatementState
to a new pendingError_ data member in IoErrorHandler.
This allows IoErrorHandler::InError() to return a correct
result when there is a pending error that will be recovered
from so that I/O list data transfers don't crash in the meantime.
3) Don't create and leak a unit for a failed OPEN(NEWUNIT=n)
with error recovery, and don't modify 'n'. (Depends on
changes to API call ordering in lowering, in a separate patch;
code was added to ensure that OPEN statement control list
specifiers, e.g. SetFile(), must be passed before GetNewUnit().)
4) Fix the code that calls a form of strerror to fill an
IOMSG= variable so that it actually works for Fortran's
character type: blank fill with no null or newline termination.

This patch adds parser nodes for each indivudual section in sections
construct. This should help with the translation to FIR. `!$omp section`
was not recognized as a construct and hence needed special handling.
`OpenMPSectionsConstruct` contains a list of `OpenMPConstruct`. Each
such `OpenMPConstruct` wraps an `OpenMPSectionConstruct`
(section, not sections). An `OpenMPSectionConstruct` is a wrapper around

When creating an array temporary in the array copy pass, care must be
taken with allocatable components. The element components needs to be
given a clean unallocated status before being used in the assignments.
This is because assignment of allocatable components makes deep copy,
and may cause deallocation of the previous value if it was allocated.
Hence the previous allocation status cannot be let undefined.
On top of that, when cleaning-up the temp, all allocatable components
that may have been allocated must be deallocated.
This patch implements this by centralizing the code making and cleaning
array temps in ArrayValueCopy.cpp, and by calling Initialize and Destroy
runtime entry points when they are allocatable components.

functional aspects of the move, but various aspects are left untouched
to ease migration: func::FuncOp is re-exported into mlir to reduce
the actual API churn, the assembly format still accepts the unqualified
`func`. These temporary measures will remain for a little while to

Allow fir.rebox input and output element type to differ for characters
if:
- Any of the character type is dynamic. Fortran allows making pointer
assignments between deferred and constant lengths entities, making this
case useful (if the input length is dynamic and the output length constant,
it is a user requirement that the length matches at runtime. There is no
option to check this at runtime, but it could be added as an option to
fir.rebox codegen later if desired).
- Or, there is a slice in the fir.rebox (the fir.rebox can implement a
substring view, hence the constant output and input lengths).
This is only a verifier constraint change, the fir.rebox codegen is not
impacted and already support those cases.
