Detailed Description
This instruction is optional and marks the last use of temporaries introduced by SAIL.
Since SAIL often introduces a very large number of temporaries, cleaning the temporaries up after their last use is often a good idea. DropVariable instructions are generated only if ADD_DROP_TEMP_INSTRUCTIONS defined in Function.h is set to true.

| bool sail::DropVariable::is_removable | ( | ) | [virtual] |
An instruction is removable if it's not present in the original source code, but introduced in the translation from the high-level language to the low-level language. For instance, if **x is an expression used in the original code, the low-level language will introduce a temporary t=*x; such instructions are "removable" for printing purposes.
Implements sail::Instruction.
