EVM Compiler

Compiles an AST (Abstract Syntax Tree) to Ethereum Virtual Machine bytecodes, WIP.

Design

TBD

Versions

• 0.0.1 First published version
• 0.0.2 Fix check datasize; fix binary order evaluation; using geast@0.0.7
• 0.0.3 Process local variables, loop and conditional commands
• 0.0.4 Process break and continue commands
• 0.0.5 For command, fnhash in API, stop in void method, local variables management first implementation
• 0.0.6 Array variable declaration and access, signed mod and div, process call, context redesign, logical operations, addmod mulmod operations
• 0.0.7 Attributes in method node
• 0.0.8 Using function instead of method

To Do

• Management of local variables (partial)
• Call private, internal, external methods
• Pass arguments in stack when needed
• Returns result in stack when needed
• Contract inheritance
• String support
• Mapping support
• Dynamic arrays support
• Static array support
• Call another contract
• Transfer value to another address
• Pure, view methods
• Generate ABI
