llvm-mirror/include/llvm/Support/IRBuilder.h
Duncan Sands 0f1ba9dee5 Add a NullFolder class that doesn't fold constants. 
This may be used as the second IRBuilder template
parameter, the idea being that people learning LLVM
may find it helpful (several people asked on IRC
if it was possible to turn off constant folding
because it made it hard for them to see what was
going on).  Compiles, but otherwise completely
untested.

/// I->setName(). For access to extra instruction properties, use the mutators
/// (e.g. setVolatile) on the instructions after they have been created.
/// The first template argument handles whether or not to preserve names in the
/// final instruction output. This defaults to on. The second template argument
/// specifies a class to use for creating constants. This defaults to creating
