Douglas Gregor 5253768ada Introduce a representation for types that we referred to via a
qualified name, e.g., 

  foo::x

so that we retain the nested-name-specifier as written in the source
code and can reproduce that qualified name when printing the types
back (e.g., in diagnostics). This is PR3493, which won't be complete
until finished the other tasks mentioned near the end of this commit.

The parser's representation of nested-name-specifiers, CXXScopeSpec,
is now a bit fatter, because it needs to contain the scopes that
precede each '::' and keep track of whether the global scoping
operator '::' was at the beginning. For example, we need to keep track
of the leading '::', 'foo', and 'bar' in
 
  ::foo::bar::x

The Action's CXXScopeTy * is no longer a DeclContext *. It's now the
opaque version of the new NestedNameSpecifier, which contains a single
component of a nested-name-specifier (either a DeclContext * or a Type
*, bitmangled). 

The new sugar type QualifiedNameType composes a sequence of
NestedNameSpecifiers with a representation of the type we're actually
referring to. At present, we only build QualifiedNameType nodes within
Sema::getTypeName. This will be extended to other type-constructing
actions (e.g., ActOnClassTemplateId).

Also on the way: QualifiedDeclRefExprs will also store a sequence of
NestedNameSpecifiers, so that we can print out the property
nested-name-specifier. I expect to also use this for handling
dependent names like Fibonacci<I - 1>::value.

llvm-svn: 65659
2009-02-27 23:15:07 +00:00
Douglas Gregor deaad8cc34 Create a new TypeNodes.def file that enumerates all of the types,
giving them rough classifications (normal types, never-canonical
types, always-dependent types, abstract type representations) and
making it far easier to make sure that we've hit all of the cases when
decoding types. 

Switched some switch() statements on the type class over to using this
mechanism, and filtering out those things we don't care about. For
example, CodeGen should never see always-dependent or non-canonical
types, while debug info generation should never see always-dependent
types. More switch() statements on the type class need to be moved 
over to using this approach, so that we'll get warnings when we add a
new type then fail to account for it somewhere in the compiler.

As part of this, some types have been renamed:

  TypeOfExpr -> TypeOfExprType
  FunctionTypeProto -> FunctionProtoType
  FunctionTypeNoProto -> FunctionNoProtoType

There shouldn't be any functionality change...

Daniel Dunbar 56493b0d54 Allow creation of "dummy" compile units for debug information.
- Although gross, this is needed currently to ensure that we produce
   well formed debug information (to match pace with the assertions
   being added to DebugInfo in LLVM).

Douglas Gregor 91f84216f7 Unifies the name-lookup mechanisms used in various parts of the AST
and separates lexical name lookup from qualified name lookup. In
particular:
  * Make DeclContext the central data structure for storing and
    looking up declarations within existing declarations, e.g., members
    of structs/unions/classes, enumerators in C++0x enums, members of
    C++ namespaces, and (later) members of Objective-C
    interfaces/implementations. DeclContext uses a lazily-constructed
    data structure optimized for fast lookup (array for small contexts,
    hash table for larger contexts). 

  * Implement C++ qualified name lookup in terms of lookup into
    DeclContext.

  * Implement C++ unqualified name lookup in terms of
    qualified+unqualified name lookup (since unqualified lookup is not
    purely lexical in C++!)

  * Limit the use of the chains of declarations stored in
    IdentifierInfo to those names declared lexically.

  * Eliminate CXXFieldDecl, collapsing its behavior into
    FieldDecl. (FieldDecl is now a ScopedDecl).

  * Make RecordDecl into a DeclContext and eliminates its
    Members/NumMembers fields (since one can just iterate through the
    DeclContext to get the fields).

Chris Lattner f3d3faeca6 Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of
uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

Chris Lattner 86d7d91366 Rename NamedDecl::getIdentifierName() to ::getNameAsCString() and make it
assert if the name is not an identifier.  Update callers to do the right
thing and avoid this method in unsafe cases.  This also fixes an objc
warning that was missing a space, and migrates a couple more to taking
IdentifierInfo and QualTypes instead of std::strings.

Douglas Gregor 77324f3854 Introduction the DeclarationName class, as a single, general method of
representing the names of declarations in the C family of
languages. DeclarationName is used in NamedDecl to store the name of
the declaration (naturally), and ObjCMethodDecl is now a NamedDecl.

Chris Lattner f61801403d Fix even more bugs in debug info support:
1. emit proper debug info for forward decls of structs.
2. emit DW_TAG_member nodes around members of a field like llvm-gcc does.

This slows down debug info generation, but is required for correctness.

llvm-svn: 58973
2008-11-10 06:10:01 +00:00
Chris Lattner affb37337f reimplement debug info generation in terms of DebugInfo.h instead of

code, but fixes a bunch of bugs and is simpler and shorter.

2008-10-24 08:38:36 +00:00
Daniel Dunbar 607f67b16c Map compilation units using FileEntry pointers instead of
FileIDs. This seems better conceptually and lets the SourceManager
handle details of mapping the location to a file ID.
 - In practice, fixes an assert because this code wasn't using
   getPhysicalLoc.

Daniel Dunbar 380827cfa1 Quick patch for PR2784, assert genereting debug info for opaque

Chris Lattner c893a67fe3 update to make IRBuilder API change.
llvm-svn: 54548
2008-08-08 19:57:58 +00:00
Chris Lattner 7adf076088 Finally fix PR2189. This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

Eli Friedman b65ff27f53 A couple minor fixes to make debug info usable for arbitrary code: don't
emit incomplete types, because they crash llc, and always use the 
logical location as the current location so we don't crash doing invalid 
queries on CurLoc.

2008-05-25 05:15:42 +00:00
Eli Friedman 1763075b9c Make debugging information usable. This is barebones, but it makes -g
actually work (instead of crashing llc), and there's enough info emitted 
to get line number information in gdb. This should hopefully be helpful 
for debugging non-working programs.

I got rid of the begin/endregion calls because the implementation wasn't 
working; someone who knows the debugging info a bit better might try to 
add it. I really have no clue how a compiler is supposed to emit them.

This commit shouldn't have any effect without -g.
