6 years ago[flang] Add name resolution tests
Tim Keith [Fri, 15 Jun 2018 21:54:34 +0000 (14:54 -0700)]
[flang] Add name resolution tests

The Fortran source files in test/semantics all contain expected
errors in comments. The script test_errors.sh compiles a file with
'f18 -fdebug-resolve-names -fparse-only' and compares the actual
errors produced against the expected ones.

The change to resolve15.f90 is necessary because test_errors.sh can't
handle two expected errors for the same source line.

A useful command to run these is 'ctest -R f90 --output-on-failure'.
-R means only run tests with f90 in the name
--output-on-failure prints the output of test_errors.sh when a test
fails, showing the expected and actual messages that differ.

[flang] Remove extraneous Pre/Post for ProcedureDeclarationStmt

clang give a compilation error on resolve-names.cc because there are
two overloadings of Pre(ProcedureDeclarationStmt) available in
ResolveNamesVisitor. One is defined in DeclTypeSpecVisitor and the other
in DeclarationVisitor. They are both brought in to ResolveNamesVisitor
via `using` statements.

The one in DeclarationVisitor is the one that is supposed to be called.
The other should have been removed when this one was added. This is the
one that gcc chooses to call, so this doesn't change any behavior.

The same applies to the Post method as well.

[flang] Improvements to generics.

When a generic or specific procedure is use-associated, make a copy of
it in the current scope (replacing the symbol that has UseDetails) so
that we can make changes to it. This permits a generic to be defined in
one module and extended with more specific procedures in another.

When a specific procedure has the same name as its generic, it can't be
stored directly in the scope because that is indexed by name and the
generic is already there. So instead we store the specific in the
GenericDetails of the generic symbol.

Enforce the rule that a generic and a procedure can only have the same
name if the procedure is one of the specifics of the generic.

Refactorings done is support of this change:
- Add FindSymbol() and EraseSymbol() as helpers to find or erase a
  symbol in the current scope. Make use of FindSymbol() where appropriate.
- Add SayAlreadyDeclared() to report a common error.

still to be done.

6 years ago[flang] Support interface blocks.
Tim Keith [Mon, 14 May 2018 20:51:13 +0000 (13:51 -0700)]
[flang] Support interface blocks.

Add subprogram symbols for each interface-body and set isInterface on
them. Create a symbol with GenericDetails for each generic interface
block and add interface specifications to the specific procedures of
the generic. InterfaceVisitor takes care of this.

Before processing the specification part of modules and subprograms,
collect the names of module subprograms and internal subprograms and add
them to the symbol table with SubprogramNameDetails. This allows us to
reference them from interface blocks in the specification part.
SubprogramNameDetails is converted to SubprogramDetails when the real
subprogram is visited.

This is achieved by setting subpNamesOnly_ and then walking the
ModuleSubprogramPart or InternalSubprogramPart. Creating the symbol and
scope for a module or subprogram now happens when the Module,
SubroutineSubprogram, or FunctionSubprogram node is encountered so
this can happen in the right order.

Add BeginSubprogram and EndSubprogram to handle the parts in common
between subprograms and interface specifications.

Add GenericSpec to type.h to represent all possible generic specs.
Only generic names are resolved so far.

Add tests for new error messages. Change resolve02.f90 to reflect the
new errors reported.

Tim Keith [Fri, 4 May 2018 22:37:56 +0000 (15:37 -0700)]
[flang] Extract class SubprogramVisitor out of ResolveNamesVisitor.

This is just refactoring. SubprogramVisitor now contains the functionality
related to subprograms, including statement functions. This is preparation
for handling interface blocks.

Also, change MessageHandler to create the Messages object and return it
through an accessor rather than having it created outside and passed in.
This saves us from having to pass it up through the chain of constructors.
