Chris Lattner 93236ba327 add support for forwarding mem intrinsic values to non-local loads. 
llvm-svn: 90697
 2009-12-06 04:54:31 +00:00
Chris Lattner 850a3cd905 gvn is optimizing this better now. 
llvm-svn: 90696
 2009-12-06 04:16:05 +00:00
Chris Lattner 42376066eb Handle forwarding local memsets to loads. For example, we optimize this: 
short x(short *A) {
  memset(A, 1, sizeof(*A)*100);
  return A[42];
}

to 'return 257' instead of doing the load.

Chris Lattner d15e11ad98 Add helper methods for forming shift operations with a constant 
shift amount.

Steve Naroff 287a2bfc03 Integrate the following from the 'objective-rewrite' branch: 
http://llvm.org/viewvc/llvm-project?view=rev&revision=86026

Note: The 'improved debugging' changes weren't integrated (since they were later reverted, since they didn't improve debugging).

Anders Carlsson 4ed44eb7d9 Only emit the vtable definition if the class has a key function and we're emitting it, or if the class doesn't have a key function and we are emitting the complete constructor.
