string.

That said, we should probably try and track down the correct clobber 
lists for the targets that don't have them (PPC, ARM, and Sparc), 
so that we can generate correct code.

which can refer to static data members, enumerators, and member
functions as well as to non-static data members.

Implement correct lvalue computation for member references in C++. 
Compute the result type of non-static data members of reference type properly.

warning by using an unsigned index.

llvm-svn: 61292

simple test that actually does VLA codegen.

Note that despite the fact that the alloca isn't in the entry block, it 
should dominate all uses; this is guaranteed by the restrictions on goto 
into VLA scope in C99.

Check the entire StackSaveValues stack for VLAs when dealing with goto and return statements. Noticed by Eli Friedman.

Emit the size even if the declared type is a variably modified type. This lets us handle

void f(int n) {
  int (*a)[n];
  
  printf("size: %d\n", sizeof(*a));
}

code gen which did not belong there.

 - Update comment to reflect fact that StructRet is now supported for
   any type (modulo LLVM support).

 - No functionality change, no scalar types currently use this
   feature.

llvm-svn: 61192

Note that one test duplicate-ivar-check.m will fail because I 
need to re-implement duplicate ivar checking.

llvm-svn: 61154

Someone should double-check that I didn't somehow break ObjC 
serialization; I think the change there actually changes the semantics.

is done. Layout is calculated lazily at code gen type.
This patch changes the name.

ivars.

llvm-svn: 61043

Store the size of the EH stack inside each BreakContinue struct so we know when a break/continue won't cross a try block.

Work in preparation for VLAs. Make sure to restore the stack if necessary (Saving the stack isn't implemented right now :)

Actually distinguish between RecordDecl::field_iterator and RecordDecl::field_const_iterator, propagating the constness down to the FieldDecls.

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).

the synthesis is in an implementation of s subclass of
a super class where the property has been declared.
