[cfe-dev] Problem with retrieving the BinaryOperator RHS end location

[Nat! via cfe-dev]

I am just trying to print the whole BinaryOperator statement text 
verbatim, but I can not get the end of the statement location.


```

bool VisitBinaryOperator(BinaryOperator  *Stmt) {
         const char       *startBuf;
         const char       *endBuf;
         SourceManager    *SM;

         SM = &TheRewriter.getSourceMgr(); // based on Rewriter
         startBuf = SM->getCharacterData( Stmt->getLHS()->getBeginLoc());
         endBuf   = SM->getCharacterData( Stmt->getRHS()->getEndLoc());
         fprintf( stderr, "write: \"%.*s\"\n", (int) (endBuf - 
startBuf), startBuf);
         return( true);
}

```


For an input of:

```

void   x( void)
{
    void  (*y)(void);

    y = x;
}

```


I get

```

write: "y = "

```


This is the dump of the AST:

```

FunctionDecl 0x19d3bd8 </home/src/srcL/llvm-clang-samples/y.m:1:1, 
line:6:1> line:1:8 referenced x 'void (void)'
`-CompoundStmt 0x19d3ec8 <line:2:1, line:6:1>
   |-DeclStmt 0x19d3e38 <line:3:4, col:20>
   | `-VarDecl 0x19d3dd8 <col:4, col:19> col:12 used y 'void (*)(void)'
   `-BinaryOperator 0x19d3ea8 <line:5:4, col:8> 'void (*)(void)' '='

<FunctionToPointerDecay>
       `-DeclRefExpr 0x19d3e70 <col:8> 'void (void)' Function 0x19d3bd8 
'x' 'void (void)'
```

This is my first foray into clang rewriting...
