[llvm-commits] CVS: llvm/lib/ExecutionEngine/Interpreter/Execution.cpp Interpreter.h

[Reid Spencer]

Changes in directory llvm/lib/ExecutionEngine/Interpreter:

Execution.cpp updated: 1.166 -> 1.167
Interpreter.h updated: 1.81 -> 1.82
---
Log message:

Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to 
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.
