A SAVE statement with no entity list applies the SAVE attribute only to
the entities that it is allowed on. We were applying it to automatic
data objects and reporting an error that they can't have SAVE.
The fix is to change `DeclarationVisitor::CheckSaveAttr` to check for
automatic objects. That controls both checking and setting the
attribute. This allows us to remove the check from `CheckSpecExpr`
(along with `symbolBeingChecked_`). Also, it was only called on constant
objects so the non-const overload can be eliminated.
The check in `CheckSpecExpr` is replaced by an explicit check for
automatic objects in modules. This caught an error in modfile03.f90 so
that part of the test was eliminated.

G++ 10.1 emits inappropriate "use of uninitialized data" warnings when

whose multiple instantiations magnified the number of warnings.
These changes dodge those warnings by making some innocuous changes to
the code. In the parser, the idiom defaulted(cut >> x), which yields a
parser that always succeeds, has been replaced with a new equivalent
pass<T>() parser that returns a default-constructed value T{} in an
arguably more readable fashion. This idiom was the only attestation of
the basic parser cut, so it has been removed and the remaining code
simplified. In Evaluate/traverse.h, a return {}; was replaced with a

Summary:
If you create an expression with parse errors, the `parser::Expr.typedExpr`
will be empty, which causes a compiler crash. The crash is caused by the
check in check-do-forall.cpp that scans all expresssions to see if `DO`
variables are being modified.
It turned out that the problem was that I was fetching subexpressions of type
`parser::Expr`, which are not guaranteed to have a non-null `typedExpr`. I
fixed this by only grabbing the top-level expression from which to gather
arguments as part of the DO loop analysis. This, in turn, exposed a problem
where I wasn't collecting all of the actual arguments in an expression. This
was caused by the fact that I wasn't recursing through the rest of the
expression after finding an argument. I fixed this by recursing through the
argument in the member function in `CollectActualArgumentsHelper`.

Summary:
Using a forward reference to define a `len` parameter causes a crash.
The underlying cause was that a previously declared type had an
erroneous expression for its `LEN` param value. When this expression
was referenced to evaluate a subsequent expression, bad things happened.
I fixed this by putting in code to detect this case.

Summary:
Some Symbol-related functions used in Evaluate were moved to
Evaluate/tools.h. This includes changing some member functions that were
replaced by non-member functions `IsDummy`, `GetUsedModule`, and
`CountLenParameters`.
Some member functions were made inline in `Scope`, `Symbol`,
`ArraySpec`, and `DeclTypeSpec`. The definitions were preceded by a
comment explaining why they are inline.
`IsConstantShape` was expanded inline in `IsDescriptor` because it isn't
used anywhere else
After this change, at least when compiling with clang on macos,
`libFortranEvaluate.a` has no undefined symbols that are satisfied by
`libFortranSemantics.a`.

Summary:
We were not detecting declaring multiple interfaces to the same procedure.
Also, we were not handling the initialization of entitiies where the associated
Symbol had previously had errors.
I added the function `IsInterfaceSet()` to ProcEntityDetails to see if
the value of `interface_` had been previously set. I then checked this
function before calling set_interface() and emitted an error message if
the interface was already set.
Also, in situations where we were emitting error messages for symbols, I
set the Error flag on the Symbol. Then when performing initialization
on the Symbol, I first check to see if the Symbol had an error.

I also changed the error messages to specify that errors in specification
expressions could arise from either bad derived type components or type

In cases where we detect a type param that was not declared, I created a symbol
marked as erroneous. That avoids subsequent semantic process for expressions
containing the symbol. This change caused me to adjust tests resolve33.f90 and
resolve34.f90. Also, I avoided putting out error messages for erroneous type
param symbols in `OkToAddComponent()` in resolve-names.cpp and in

There were several different ways of handling the option to f18 to
find predefined modules:
- test_errors.sh was created by cmake substituting
FLANG_INTRINSIC_MODULES_DIR into test_errors.sh.in
- some tests used the flang script which has the option built it
- some tests used %f18_with_includes which was replaced by the path
to f18 plus the -I option
- some included -I../../include/flang in their run command
To make this more consistent, change %f18 to include the
-intrinsic-module-directory option and use it everywhere, including
to replace %flang and %f18_with_includes. This requires changing all
of the invocations of the test scripts to put %f18 at the end so that
it can expand to more than one argument.
This eliminates the need to generate test_errors.sh which means we
don't need flang/test/Semantics/CMakeLists.txt or the %B substitution.
That makes the test_errors.sh command like the others, replacing
%B/test/Semantics/test_errors.sh with %S/test_errors.sh.
Also remove the OPTIONS: functionality as custom options can be included
in the RUN: command. And remove -I/../../include/flang as that is now
always included.

This is a wrapper around vector of NamedAttributes that keeps track of whether sorted and does some minimal effort to remain sorted (doing more, e.g., appending attributes in sorted order, could be done in follow up). It contains whether sorted and if a DictionaryAttr is queried, it caches the returned DictionaryAttr along with whether sorted.
Change MutableDictionaryAttr to always return a non-null Attribute even when empty (reserve null cases for errors). To this end change the getter to take a context as input so that the empty DictionaryAttr could be queried. Also create one instance of the empty dictionary attribute that could be reused without needing to lock context etc.
Update infer type op interface to use DictionaryAttr and use NamedAttrList to avoid incurring multiple conversion costs.

Summary:
Most of these checks were already implemented, and I just added references to
them to the code and tests. Also, much of this code was already
reviewed in the old flang/f18 GitHub repository, but I didn't get to
merge it before we switched repositories.
I implemented the check for C747 to not allow coarray components in derived
types that are of type C_PTR, C_FUNPTR, or type TEAM_TYPE.
I implemented the check for C748 that requires a data component whose type has
a coarray ultimate component to be a nonpointer, nonallocatable scalar and not
be a coarray.
I implemented the check for C750 that adds additional restrictions to the
bounds expressions of a derived type component that's an array.
These bounds expressions are sepcification expressions as defined in
10.1.11. There was already code in lib/Evaluate/check-expression.cpp to
check semantics for specification expressions, but it did not check for
the extra requirements of C750.
C750 prohibits specification functions, the intrinsic functions
ALLOCATED, ASSOCIATED, EXTENDS_TYPE_OF, PRESENT, and SAME_TYPE_AS. It
also requires every specification inquiry reference to be a constant
expression, and requires that the value of the bound not depend on the
value of a variable.
To implement these additional checks, I added code to the intrinsic proc
table to get the intrinsic class of a procedure. I also added an
enumeration to distinguish between specification expressions for
derived type component bounds versus for type parameters. I then
changed the code to pass an enumeration value to
"CheckSpecificationExpr()" to indicate that the expression was a bounds
expression and used this value to determine whether to emit an error
message when violations of C750 are found.
I changed the implementation of IsPureProcedure() to handle statement
functions and changed some references in the code that tested for the
PURE attribute to call IsPureProcedure().
I also fixed some unrelated tests that got new errors when I implemented these
new checks.

This is the interface to the conversion pass that converts the FIR dialect (and standard dialects) of MLIR to the LLVM-IR dialect. The implementation of this bridge will be forthcoming in subsequent diffs.
The purpose of the code gen bridge is to take the IR, which will be expressed as a mix of higher-level Fortran constructs as expressed in the FIR dialect and the MLIR standard dialect, and convert the representation into the LLVM-IR dialect. At that point, the LLVM-IR dialect can be converted into LLVM IR (proper) by a standard MLIR pass.

As we start defining more complex Ops, we increasingly see the need for
Ops-with-regions to be able to construct Ops within their regions in
their ::build methods. However, these methods only have access to
Builder, and not OpBuilder. Creating a local instance of OpBuilder
inside ::build and using it fails to trigger the operation creation
hooks in derived builders (e.g., ConversionPatternRewriter). In this
case, we risk breaking the logic of the derived builder. At the same
time, OpBuilder::create, which is by far the largest user of ::build
already passes "this" as the first argument, so an OpBuilder instance is
already available.
Update all ::build methods in all Ops in MLIR and Flang to take
"OpBuilder &" instead of "Builder *". Note the change from pointer and
to reference to comply with the common style in MLIR, this also ensures
all other users must change their ::build methods.
