Eric Christopher 1f272f7fd8 Verify function prototypes before trying to optimize functions. We also 
need TargetData, just return false if we don't have it.

Update testcases accordingly.

Fixes PR6807.

Dan Gohman fa5ad797e3 Re-apply r101000, with a fix: Don't eliminate an icmp which is part of 
the loop exit test. This usually doesn't come up for a variety of
reasons, but it isn't impossible, so make IndVarSimplify handle it
conservatively.

Dan Gohman af4ab1b681 Teach IndVarSimplify how to eliminate comparisons involving induction 
variables. For example, with code like this:

  for (i=0;i<n;++i)
    if (i<n)
      x[i] = 0;

IndVarSimplify will now recognize that i is always less than n inside
the loop, and eliminate the if.

Dan Gohman ae4a4148ba When creating a ConstantRange for [n,UINT_MAX], special case n == 0, because

Chris Lattner a36ec4243b fix PR6811 by not parsing 'super' as a magic expression in 
LookupInObjCMethod.  Doing so allows all sorts of invalid code
to slip through to codegen.  This patch does not change the 
AST representation of super, though that would now be a natural
thing to do since it can only be in the receiver position and
in the base of a ObjCPropertyRefExpr.

There are still several ugly areas handling super in the parser,
but this is definitely a step in the right direction.

Chris Lattner 90c58faea6 actually the interface grossness in the previous patch was due to 
typo correction.  However, now that the code has been factored out
of LookupMemberExpr, it can recurse to itself instead of to 
LookupMemberExpr!  Remove grossness.

llvm-svn: 100958
 2010-04-11 07:51:10 +00:00
Chris Lattner 2b1ca5fb8a factor the code that handles "expr.field" when expr is a 
pointer to an objc interface out to a method in SemaExprObjC.
This is *much* uglier than it should be due to grossness in
LookupMemberExpr :(
