Changes in directory llvm/tools/bugpoint:
ExecutionDriver.cpp updated: 1.66 -> 1.67
---
Log message:
add a new bugpoint mode -llc-safe. This uses LLC for both halves of a
miscompilation. This is useful for working around GCC+CBE bugs or for handling
programs that CBE doesn't support (e.g. inline asm) when searching for
optimizer bugs.
