Futhark.CodeGen.Backends.SequentialWASM

C code generator. This module can convert a correct ImpCode program to an equivalent C program. This C program is expected to be converted to WebAssembly, so we also produce the intended JavaScript wrapper.

Documentation

compileProg :: MonadFreshNames m => Text -> Prog SeqMem -> m (Warnings, (CParts, Text, [String]))

Compile Futhark program to wasm program (some assembly required).

The triple that is returned consists of

• Generated C code (to be passed to Emscripten).
• JavaScript wrapper code that presents a nicer interface to the Emscripten-produced code (this should be put in a .class.js file by itself).
• Options that should be passed to emcc.

runServer :: Text

Javascript code that can be appended to the generated module to run a Futhark server instance on startup.

libraryExports :: Text

The names exported by the generated module.

data CParts

The result of compilation to C is multiple parts, which can be put together in various ways. The obvious way is to concatenate all of them, which yields a CLI program. Another is to compile the library part by itself, and use the header file to call into it.

Constructors

CParts

Fields

• cHeader :: Text
• cUtils :: Text

  Utility definitions that must be visible to both CLI and library parts.

• cCLI :: Text
• cServer :: Text
• cLib :: Text
• cJsonManifest :: Text

asLibrary :: CParts -> (Text, Text, Text)

Produce header, implementation, and manifest files.

asExecutable :: CParts -> Text
