Yhc/API/Bytecode
| Part of Yhc |
On the step towards a full API for the whole compiler, an API for just the bytecode first will probably be desirable.
There are two entirely separate lumps in this, the raw bytecode, and the wrappers that make a module file.

1 Module
data Module = Module {objects :: [Object]}
data PackageVer = PackageVer {version :: [Int], name :: String}
data ModuleName = ModuleName PackageVer {name :: String}
data Import = Import ModuleName {name :: String, arity :: Int}
data Export = Export {name :: String, obj :: Object, arity :: Int}
data Object = Function Arity ConstTable HufByteCode
| Constructor Arity TagNo
type ConstTable = [Const]
type HufByteCode = [HufBC]

2 Bytecode
There are tree types of bytecode representation:
data GraphNode = ... data LabeledJumps = ...
Then there are the api's
instance Show GraphNode instance Show ByteCode instance Show ByteCodeHuf instance Show ... graphToByteCode :: GraphNode -> ByteCode byteCodeToGraph :: ByteCode -> GraphNode byteCodeCompress :: ByteCode -> ByteCodeHuf byteCodeInflate :: ByteCodeHuf -> ByteCode
writeModule :: Module -> FilePath -> IO () readModule :: FilePath -> IO Module
-- do memory and zapping analysis memAnalysis :: a -> a
-- peep hole optimisations peephole :: a -> a
