2007-08-28Tweak declaration...Steve Naroff
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41542 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-28Implement more thoughful error recovery when dealing with bogus declarator ↵Steve Naroff
types. For example, the following code was resulting in spurious warnings. This was the result of Sema::GetTypeForDeclarator() synthesizing a type to hand back to the caller (in this case, "int []", instead of "struct s[]", which is invalid). struct s; struct s* t (struct s z[]) { // expected-error {{array has incomplete element type}} return z; } Strategy: Flag the error in Declarator/DeclaratorChunk. This info is later stored in the ParmVarDecl. If the decl is referenced, Sema::ParseIdentifierExpr() will check if the type is invalid. If so, it quietly returns "true", without instantiating a DeclRefExpr. This seems to work nicely. If Chris is happy with the approach, I will generalize this to all VarDecls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41521 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-26Break the assumption that any sort of scope (e.g. a loop scope) can Chris Lattner
hold declarations. Instead, introduce a new "DeclScope" scope type that holds them explicitly. For now, all scopes have this bit, but in the future we can use them to fix some issues Neil noticed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41431 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-23As suggested by Chris, use MatchRHSPunctuation instead of manually looking ↵Anders Carlsson
for a right parenthesis when parsing @encode() and @protocol(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41321 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-22Add support for parsing protocols.Steve Naroff
Now we can parse quite a bit of "Foundation.h" (a couple bugs remain). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41300 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-22Finish up method prototype parsing.Steve Naroff
Next step...starting installing class names into the type namespace (so we can start parsing Cocoa headers). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41283 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-22Add support for parsing method prototypes (and other stuff required by ↵Steve Naroff
@interface). Still need to finish Parser::ParseObjCMethodDecl(). Before I do, I need to do a minor refactoring of ParseDeclarationOrFunctionDefinition(), to disallow function definitions. At the moment, @inteface allows function defs (which is incorrect). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41275 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-22Fix the scoping issue Neil pointed out for the rest ofChris Lattner
the selection statements and iteration statements. Add spec citations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41264 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41245 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-21Tweak error recovery for missing semicolon after decl. For this:Chris Lattner
void foo() { int x if (x) { } } We now emit: a.c:5:3: error: parse error if (x) { ^ 1 diagnostic generated. instead of: a.c:5:3: error: parse error if (x) { ^ a.c:9:1: error: expected '}' ^ 2 diagnostics generated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41243 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-20Added Parser::ParseStructDeclaration() as a result of refactoring ↵Steve Naroff
Parser::ParseStructUnionBody(). Motivation: Objective-C can now share this rule. It also makes Parser::ParseStructUnionBody() a bit smaller/cleaner.. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41201 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-20Start parsing ObjC classes/categories!Steve Naroff
Next step, refactor Parser::ParseStructUnionBody() so that struct declarations can be shared with Objective-C (for declaring instance variables). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41200 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40713 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-01- Finish hooking up support for __builtin_types_compatible_p().Steve Naroff
- Fix type printing code for recently added TypeOfExpr/TypeOfType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40700 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-01Add AST/Sema support for __builtin_types_compatible_p (a GNU extension).Steve Naroff
Todo...still need to call the action from the parser... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40693 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-31Tighten up Parser::ParseTypeofSpecifier().Steve Naroff
Add some more tests to typeof.c. Also added a couple of missing "expect" attributes that caused the test to fail. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40656 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-31Add parsing and AST support for GNU "typeof".Steve Naroff
Many small changes to lot's of files. Still some FIXME's, however the basic support is in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40631 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-25Fix a couple of bugs, add some new cool stuff.Chris Lattner
1. Fix a todo in Parser::ParseTag, to recover better. On code like that in test/Sema/decl-invalid.c it causes us to return a single error instead of multiple. 2. Fix an error in Sema::ParseDeclarator, where it would crash if the declarator didn't have an identifier. Instead, diagnose the problem. 3. Start adding infrastructure to track the range of locations covered by a declspec or declarator. This is mostly implemented for declspec, but could be improved, it is missing for declarator. Thanks to Neil for pointing out this crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40482 91177308-0d34-0410-b5e6-96231b3b80d8
