Description

Choose the Garbage Collector used by the translated program:

• "ref": reference counting. Takes very long to translate and the result is slow.
• "marksweep": naive mark & sweep.
• "semispace": a copying semi-space GC.
• "generation": a generational GC using the semi-space GC for the older generation.
• "boehm": use the Boehm conservative GC.
