◆ getWeight()

uint64_t InstDeleterIRStrategy::getWeight ( size_t  CurrentSize,
size_t  MaxSize,
uint64_t  CurrentWeight 

Provide a weight to bias towards choosing this strategy for a mutation.

The value of the weight is arbitrary, but a good default is "the number of distinct ways in which this strategy can mutate a unit". This can also be used to prefer strategies that shrink the overall size of the result when we start getting close to MaxSize.

Implements llvm::IRMutationStrategy.
