Sjit

Sjit is a stupid just in time compiler. It does almost nothing, and what it does, it does badly and is not useful.

• There is no type checker, you have to guess the implicit rules.
• There is no register allocation, everything is done on the stack.
• There is no code optimisation, not even to eliminate push rbx followed by pop rbx.
• JIT generated code is for the x64 instruction set only.
• Because we use mmap and mprotect this only works on POSIX systems.

Usage

git clone https://gitlab.science.ru.nl/cstaps/sjit-compiler
