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

[Reid Spencer]

Changes in directory llvm/lib/ExecutionEngine/Interpreter:

Interpreter.h updated: 1.83 -> 1.84
---
Log message:

1. Have the ExecutionContext keep track of the APInt's allocated and 
   ensure they are cleaned up when the stack frame exits.
2. Move a function to the Execution.cpp file where it belongs.
