both Preprocessor and ASTContext, we no longer need to explicitly pass
MainFileID around in function calls that also pass either Preprocessor or
ASTContext. This resulted in some nice cleanups in the ASTConsumers and the
driver.

Add DefaultFunctionArrayConversion() to the indirection operator in Sema::ActOnUnaryOp().

This fixes a bug Chris forwarded from Oliver Hunt...

typedef struct { char name[100]; } entry;
char f1(entry *e) { return *e->name; }

Fixe bogus error for variable argument methods. Sema::ObjcGetTypeForMethodDefinition() wasn't preserving the isVariadic boolean. Another fix is to avoid synthsizing the function decl entirely, however this is a separate issue that I don't want to deal with now. Also added a FIXME to Sema::CheckFunctionCall(), which is currently emitting a bogus warning.

llvm-svn: 45146

Improve how we find private method decls. This involved:

- Changed Sema::ObjcActOnStartOfMethodDef() to register the methods with the global pools.
- Changed Sema::ActOnInstanceMessage() to look in global pools (should be much less error prone).
- Added a test case to message.m (for lookup that was broken).

Misc changes while I was investigating this...

- Changed Sema::ActOnAtEnd() to call AddFactoryMethodToGlobalPool (this looked like a cut/paste error).
- Added a comment and tweaked another where I was using the first person.

the protocol list (id<P,...> types).

llvm-svn: 45121

following hold:

(1) A vprintf-like function is called that takes the argument list via a
    via_list argument.

(2) The format string is a non-literal that is the parameter value of
    the enclosing function, e.g:
    
    void logmessage(const char *fmt,...) { 
      va_list ap;
      va_start(ap,fmt);
      fprintf(fmt,ap);  // Do not emit a warning.
    }
    
In the future this special case will be enhanced to consult the "format"
attribute attached to a function declaration instead of just allowing a blank
check for all function parameters to be used as format strings to vprintf-like
functions. This will happen when more support for attributes becomes
available.

Sema::ActOnMemberReferenceExpr() needs to perform the default conversions.

Bug and test case provided by Carl Lewis.

llvm-svn: 45078

- Remove getInstanceMethods/getClassMethods API on ObjcInterfaceDecl, ObjcProtocolDecl, and ObjcCategoryDecl. These methods are replaced by the respective iterators on each class.
- Add getInstanceMethodForSelector to ObjcInterfaceDecl, ObjcProtocolDecl, and ObjcCatgoryDecl. This hook will do a "shallow" lookup. This is a convenience method that reducing some of the iterator usage.
- Various changes to convert all clients to the above API's...

Don't do integer promotions of LHS for compound shift assignment.  The LHS has to be a modifiable lvalue.

Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:

    FullLoc.getManager().someMethod(FullLoc.getLocation());
    
instead we have:

    FullLoc.someMethod();
    
Modified TextDiagnostics (and related classes) to use this short-hand.

int test(int x, long long y) {
  return x << y;

we now realize the type of the shift is int, not long long.

This fixes a fixme from june.

this is passed to sema and ignored there, so the second part of the
string will not make it into the AST.  Passing to Fariborz to finish
Sema + AST construction.

SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.

Modified all users of Diagnostics to comply with this new interface.

Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).

Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.

Change err_undef_protocolref to warn_undef_protocolref (this is consistent with GCC).

Explicitly set the string literal type from "char *" to "constant array of char".

At this point, I am fairly certain the front-end is correct. Unfortunately, the back-end is still unhappy.

That said, I've commented out the two lines in globalinit.c that are causing problems.

Chris, please have a look...thanks!
