A disassembler for ByteCode objects as used by GHCi.

Documentation

toBytes :: Word -> [Word] -> ByteString

Converts the first n bytes of this list of Words to a ByteString.

disassemble :: forall box. [box] -> [Word] -> ByteString -> [BCI box]

Given a list of pointers, a list of literals and a ByteString containing byte code instructions, disassembles them into a list of byte code instructions.

data BCI box

The various byte code instructions that GHCi supports.
