Tim Keith 3ec5e102e2 [flang] Name resolution for defined operators
Instead of tracking just genericName_ while in a generic interface
block or generic statement, now we immediately create a symbol for it.
A parser::Name isn't good enough because a defined-operator or
defined-io-generic-spec doesn't have a name.

Change the parse tree to add a source field to GenericSpec. Use these
as names for symbols for defined-operator and defined-io-generic-spec
(e.g. "operator(+)" or "read(formatted)").

Change the source for defined-op-name to include the dots so that they
can be distinguished from normal symbols with the same name (e.g. you
can have both ".foo." and "foo"). These symbols have names in the symbol
table like ".foo.", not "operator(.foo.)", because references to them
have that form.

Add GenericKind enum to GenericDetails and GenericBindingDetails.
This allows us to know a symbol is "assignment(=)", for example,
without having to do a string comparison.

Add GenericSpecInfo to handle analyzing the various kinds of
generic-spec and generating symbol names and GenericKind for them.

Add reference to LanguageFeatureControl to SemanticsContext so that
they can be checked during semantics. For this change, if
LogicalAbbreviations is enabled, report an error if the user tries
to define an operator named ".T." or ".F.".

Add resolve-name-utils.cc to hold utility functions and classes that
don't have to be in the ResolveNamesVisitor class hierarchy. The goal
is to reduce the size of resolve-names.cc where possible.

Tim Keith 7edb7ec69b [flang] Add top-level Semantics class
Refactor to create the Semantics class that is responsible for holding
state during semantics (the scope tree and messages) and managing the
logic of the various phases of semantic processing. Eliminate static
Scope::globalScope.

The messages generated during semantic processing are accumulated in a
Messages data member of Semantics so that individual phases don't need
to emit them to std::cerr. This is now done by the driver so that it has
control over where they go and eliminates other includes of iostream.
To do this, the messages object is passed in to the various semantics
operations.

Move DumpSymbols into semantics.cc: it doesn't belong in resolve-names.cc
and it depends on the global scope, so it's as good a place as any.
The call to RewriteParseTree is also moved to Semantics.

Tim Keith ae3b96456f [flang] Simplify representation of intrinsic types
Intrinsic types are now just a TypeCategory and a int kind. If no kind
is specified the default is used so that every type has an explicit
kind. This caused changes in the expected results of some of the tests.

Add support for "double precision" and "double complex".

Intrinsic types are now stored as values in DeclTypeSpec so none of the
KindedTypeHelper machinery is needed any more.

Eliminate DerivedTypeDef, DataComponentDef, ProcComponentDef,
TypeBoundProc. The components and bindings of a derived type are now
represented by the corresponding Scope.

Tim Keith 96b187efdf [flang] Add support for submodules
Symbols for submodules have `ModuleDetails` with `isSubmodule` set.
Scopes for submodules have `Module` kind and have a parent scope that
is also `Module` kind.

Scopes for modules now contain a mapping of submodule name to scope
so that we can find them without having to search the scope tree or
re-read their `.mod` file.

The module file for submodule `s` with ancestor module `m` is named `m-s.mod`.
The tree structure of scopes means module file writing is now recursive.
Similarly, reading the module file for a submodule may require reading
the module files of its parent and ancestor. `ResolveNames` now requires
the parent scope to be passed in -- it is not always the global scope.

`test_modfiles.sh` now handles an argument that is a filename glob so
that the test can involve multiple files. This allows `modfile09` to
test reading of `.mod` files for modules and submodules.

To support this, reorganize `ModFileWriter` to be more like `ModFileReader`.
The gives the client a way to set the output directory and fetch the

Tim Keith f62f8b655d [flang] Implement reading of module files
When a use-stmt is encountered for a module that isn't in the global
scope, search for and read the appropriate `.mod` file. To perform the
search, pass the search directories in to ResolveNames.

For modules that were read from `.mod` files, we have to keep the cooked
source from being deleted so that the names so that references to names
stay valid. So we store the cooked source in the Scope of the module as
a `unique_ptr`.

Add `Symbol::Flag::ModFile` to distinguish module symbols that were read
from a `.mod` file rather than from the current compilation. Use it to
prevent writing those back out.

Fix test_errors.sh to run the compiler in the temp subdirectory --
otherwise tests could be affected by `.mod` files left from previous
tests.

Tim Keith 0c575ed548 [flang] Implement writing of .mod files.
Module file writing is implemented in mod-file.cc. They need to be
written after all semantic checking. Until then, for testing, write
them out whenever names are resolved.

There is a header comment in the .mod files but it is mostly a
placeholder until we can read them in and do something with it.

Rename `Symbol::details<D>` to `Symbol::get<D>`. This asserts that the
details of the symbol match D and returns that type. But we need a way
to access the details as a variant as well (not just one of its types).
`details()` is the best name for that, especially as we already have
`set_details()`. Renaming the old `details` to `get` also better matches
`has` which is used to check which variant is present.

Tim Keith 89840b5087 [flang] Support unparse with symbol annotations.
When `-fdebug-dump-symbols` is supplied with `-funparse`, include symbol
information in comments in the Fortran output. This will be used for
testing to verify that correct symbols are defined and references in
the right place.

In `UnparseWithSymbols()`, walk the parse tree and collect symbol
definitions and references, organized by statement. When a symbol is
defined across several statement it is associated with the first.
The definition of implicitly defined symbols is associated with the
first reference.

To write out the symbol information, a new optional argument is added to
`Unparse()`: it is a function that is called immediately before each
statement is unparsed. We pass in a function that prints out the symbol
information collected for that statement.

Add `Symbol::GetType()` to make it easier to write the symbol types
and add `Symbol::SetType()` for uniformity.

Tim Keith 2541df532a [flang] Name resolution for derived types.
This consists of:
- a new kind of symbols to represent them with DerivedTypeDetails
- creating symbols for derived types when they are declared
- creating a new kind of scope for the type to hold component symbols
- resolving entity declarations of objects of derived type
- resolving references to objects of derived type and to components
- handling derived types with same name as generic

Type parameters are not yet implemented.

Refactor DeclTypeSpec to be a value class wrapping an IntrinsicTypeSpec
or a DerivedTypeSpec (or neither in the TypeStar and ClassStar cases).
Store DerivedTypeSpec objects in a new structure the current scope
MakeDerivedTypeSpec so that DeclTypeSpec can just contain a pointer to
them, as it currently does for intrinsic types.

In GenericDetails, add derivedType field to handle case where generic
and derived type have the same name. The generic is in the scope and the
derived type is referenced from the generic, similar to the case where a
generic and specific have the same name. When one of these names is
mis-recognized, we sometimes have to fix up the 'occurrences' lists
of the symbols.

Assign implicit types as soon as an entity is encountered that requires
one. Otherwise implicit derived types won't work. When we see 'x%y' we
have to know the type of x in order to resolve y. Add an Implicit flag
to mark symbols that were implicitly typed

For symbols that introduce a new scope, include a pointer back to that
scope.

Add CurrNonTypeScope() for the times when we want the current scope but
ignoring derived type scopes. For example, that happens when looking for
types or parameters, or creating implicit symbols.

Tim Keith 1c291436f5 [flang] Implement parse tree rewriting.
Add parse-tree-mutator.h like parse-tree-visitor.h except that the Walk
functions take non-const references to parse tree nodes so the Pre and
Post methods of the mutator that are passed around can make changes to
the parse tree.

Change ExecutionPart to be a class that wraps a list so that it can be
identified during parse tree walking.

Add Symbol* field to parser::Name for the result of symbol resolution.
In parse tree dumper, dump symbol when it is there instead of just name.

Add RewriteParseTree to walk the parse tree, fill in resolved symbols in
Name nodes, and make necessary changes to the structure. Currently that
consists of rewriting statement functions as array assignments when
appropriate.

In ResolveNames, call RewriteParseTree if the resolution was successful.
Recognize a statement function that comes after a mis-identified
statement function and report an error. resolve08.f90 tests this case.

Add -fdebug-dump-symbols to dump the scope tree and symbols in each scope.
This is implemented by DumpSymbols in resolve-names.cc. Add an optional
symbol to scopes that correspond to symbols (e.g. subprograms). Remove
debug output from ResolveNamesVisitor as this option can be used instead.

Tim Keith da414d7c3f [flang] Collect implicit type rules and report related errors.
ImplicitRules maintains a mapping of initial character of an identifier
to its implicit type.

ImplicitRulesVisitor visits the ImplicitStmt and related parse tree
nodes and updates the rules.

Emit errors messages in these cases:
- implicit type specified more than once for a letter
- IMPLICIT statement and IMPLICIT NONE in same scope
- IMPLICIT statement and IMPLICIT NONE(TYPE) in same scope
- more than one IMPLICIT NONE in a scope
- IMPLICIT statement with empty range of letters
- IMPLICIT NONE statement after PARAMETER statement
- TYPE or EXTERNAL repeated in an IMPLICIT NONE statement

Also start emitting error messages through the parser::Messages
interface. An instance of Messages is created from the cooked source and
saved in the MessageHandler class. It tracks the source location of the
current statement and provides a way to emit messages associated with
that statement.

peter klausler 03aecfc336 [flang] Preserve some minor changes that accumulated as I was implementing
an unparsing feature.

Enum classes in parse tree node class types are now defined with
a macro so that the names of the enumerations can be captured for
formatting purposes.

Add a TODO comment.

Rebase to new master with parse tree traversal code.

Tim Keith 2af29bc1e2 [flang] Add Unparse function.
Unparse takes a parse tree and converts it back to Fortran.
class UnparseVisitor implements a parse tree visitor that emits
the appropriate Fortran source for each node that it visits.
It is only partially implemented so far.

Change f18 to dump the parse tree using Unparse.

Tim Keith 2ca306abe1 [flang] Rename "visit" to "Walk" to avoid conflict with std::visit.
The thing called on each parse tree node during the walk is still
referred to as a visitor.

Change "pre" to "Pre" and "post" to "Post" to follow the naming
conventions.

comments, continuations, &c. that have become obsolete with the use
of the new C++-coded prescanner module.  Clean out members from
ParseState that were used only by cookedNextChar and its sub-parsers.
