Chris Lattner b352e3edb5 Change KeepComments/KeepMacroComments modes to be facets of the preprocessor 
state, not aspects of the language standard being parsed.

llvm-svn: 39204
 2006-11-21 05:01:56 +00:00
Chris Lattner b8d6d5a81d Formalize preprocessor callbacks together into a PPCallbacks structure, instead 
of having a loose collection of function pointers.  This also allows clients to
maintain state, and reduces the size of the Preprocessor.h interface.

Chris Lattner 38495cb2e7 -fsyntax-only is synonym for -parse-ast for now.

 2006-11-21 03:40:37 +00:00
Chris Lattner d8702cd845 Implement a TODO: properly invoke actions for the * in things like: 
where P is a pointer.

  int A[*P];

llvm-svn: 39199
 2006-11-21 03:12:15 +00:00
Chris Lattner a966bf6ebf fix a variable shadowing issue that caused us to misparse: 
void B() {
  memcpy (3, 2, 1);
}

where memcpy is undeclared.

 2006-11-21 01:40:01 +00:00
Chris Lattner 740b2f30c7 When a decl is popped from its current scope, link it to the decl chain for 
the containing function.  This avoids leaking decls.

llvm-svn: 39197
 2006-11-21 01:32:20 +00:00
Chris Lattner 229ce60fc9 split the ParseFunctionDefinition action into two actions, one which is 
called before and one which is called after function definition parsing.

}

llvm-svn: 39194

Chris Lattner 5efbb33a6b remember referenced decls in our AST's 
llvm-svn: 39193
 2006-11-20 05:01:40 +00:00
Chris Lattner 17ed487947 parse identifier expressions properly. This allows us diagnose this: 
typedef int X;

int A() {
  return X;
}

int B() {
  return Y;
}

as:

/Users/sabre/test.c:5:10: error: unexpected type name 'X': expected expression
return X;
       ^
/Users/sabre/test.c:9:10: error: use of undeclared 'Y' value
return Y;
       ^

typedef int G;
  X = sizeof(const G);
  X = sizeof(restrict G);

llvm-svn: 39190
 2006-11-20 04:17:27 +00:00
Chris Lattner d0342e5989 Create a new TypeNameType class, which represents typedefs as types. This 
allows us to handle stuff like:

typedef int G;
 ..
  X = sizeof(G);

llvm-svn: 39189
 2006-11-20 04:02:15 +00:00
Chris Lattner 2ebe4bb64d when a typedef name is parsed as part of declspecs, remember the decl for the 
typedef.

llvm-svn: 39186
 2006-11-19 23:16:18 +00:00
Chris Lattner da8aa7b3a8 implement RTTI for Decl objects, eliminate some hokey virtual methods. 
llvm-svn: 39185
 2006-11-19 23:12:30 +00:00
Chris Lattner 200bdc3b90 add an action method for declspecs without declarators, like "struct foo;". 
llvm-svn: 39184
 2006-11-19 02:43:37 +00:00
Chris Lattner 94c22cd5b9 rename ParsedClassDeclaration -> ParsedObjcClassDeclaration. 
llvm-svn: 39183
 2006-11-19 02:35:21 +00:00
Chris Lattner 302b4be4c2 build TypedefDecl objects when parsing typedefs. 
Add a parsing fastpath for when we see typedef at the top-level.

llvm-svn: 39182
 2006-11-19 02:31:38 +00:00
Chris Lattner 33e8a55ed0 Parse and remember types enough that we can pretty print: 
void foo(int X) {
  X = __alignof(int);
  X = sizeof(const int** restrict ** volatile*);
}

as:

x = __alignof(int)
x = sizeof(int const **restrict **volatile *)

llvm-svn: 39181
 2006-11-19 01:48:02 +00:00

llvm-svn: 39179
 2006-11-19 01:17:45 +00:00
Chris Lattner 9dfdb3c70d rearrange the type printing code so that we can do the horrible C "inside out" 
thing properly.  This allows us to print types like:
int (*A)[restrict static 4][6];

properly, in addition to representing them properly. :)

llvm-svn: 39178
 2006-11-13 07:38:09 +00:00
Chris Lattner d235d162d0 change print methods to render into a string, which is more useful for diagnostics 
and for handling precedence of types more accurately

llvm-svn: 39177
 2006-11-13 06:22:30 +00:00
Chris Lattner 7ccecb90d4 Implement parsing, printing and AST'ing of array types (except for the bounds). 
This allows us to handle:

int (*A)[restrict static 4][6];

for example.

llvm-svn: 39176
 2006-11-12 08:50:50 +00:00
Chris Lattner 47814666e1 Implement and use isa/dyncast/cast etc for Type classes. 
llvm-svn: 39175
 2006-11-12 00:56:20 +00:00
Chris Lattner d5973ebbe2 Teach ASTContext to delete all created types in its dtor. 
Teach getPointerType to (stupidly) memoize all created pointers.
Give types an enum so we can implement classof.

llvm-svn: 39174
 2006-11-12 00:53:46 +00:00
Chris Lattner 970e54e3ac Build ASTs for the pointer qualifiers on declarators. This allows us to 
parse (and print) things like:

int* const* restrict* const volatile***

etc.

llvm-svn: 39173
 2006-11-12 00:37:36 +00:00
Chris Lattner aecbefa519 We can now parse and remember the distinction between: 
'unsigned char' and 'unsigned char const'.
