Nate Begeman d5b534e16f Fix for EmitCallExpr changed in OverloadExpr patch 
llvm-svn: 46135
 2008-01-17 18:03:22 +00:00
Nate Begeman 1e36a85f64 Implement basic overload support via a new builtin, __builtin_overload. 
__builtin_overload takes 2 or more arguments:
0) a non-zero constant-expr for the number of arguments the overloaded 
   functions will take
1) the arguments to pass to the matching overloaded function
2) a list of functions to match.

The return type of __builtin_overload is inferred from the function whose args
match the types of the arguments passed to the builtin.  For example:

float a;
float sinf(float);
int   sini(int);

float b = __builtin_overload(1, a, sini, sinf);

Says that we are overloading functions that take one argument, and trying to 
pass an argument of the same type as 'a'.  sini() does not match since it takes
and argument of type int.  sinf does match, so at codegen time this will turn
into float b = sinf(a);

we emit stuff like this:

                       ^~~~~~~~~~~~~~~~~~~~~~~~

Ted Kremenek 1daa3cfbae TargetInfo no longer includes a reference to SourceManager. 
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.

llvm-svn: 44879
 2007-12-11 21:33:16 +00:00
Ted Kremenek d4e5fbacab Mega-patch: ripped SourceManager out of Diagnostic/DiagnosticClient. Now 
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.
