llvm-svn: 38889
 2006-08-12 18:40:31 +00:00
Chris Lattner 9fab3b9486 Implement parsing of 'int A[X];' by tying into the expression parsing code. 
Turn a bunch of fixme's into todo's.

llvm-svn: 38888
 2006-08-12 18:25:42 +00:00
Chris Lattner 0c6c034c48 Two fixes: 
1. Allow argument list of a call to be empty.
2. Handle expressions in a statement context that start with an identifier.
   These are nasty to handle due to the 'label:' production which requires
   having two tokens of look-ahead, or by having tricky code (which we
   choose to do).

 2006-08-12 17:18:19 +00:00
Chris Lattner 96c3deb53d Simplify handling of the ternary operator even more. Now it just looks like 
any average right-associative operator to most of the code.

llvm-svn: 38880
 2006-08-12 17:13:08 +00:00
Chris Lattner d35c34f44d Fix incorrect parsing of the ?: middle term, which is supposed to be 
parsed as 'expression'.  This implements test/Parser/statements.c

llvm-svn: 38879

Chris Lattner a0927cecb5 Improve diagnostics on cases like: 
return a ? `  a;

semicolon is not also diagnosed.
