[llvm-commits] CVS: llvm/lib/Target/IA64/IA64ISelPattern.cpp

[Andrew Lenharth]

Changes in directory llvm/lib/Target/IA64:

IA64ISelPattern.cpp updated: 1.30 -> 1.31
---
Log message:

Implement Value* tracking for loads and stores in the selection DAG.  This enables one to use alias analysis in the backends.

(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*.  Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.
