A language implemented with help of llvm tools.

This project is a compiler which uses llvm tools to generate an llvm intermediate representation(llvm-IR) and then llvm-IR is translated to machine code also using an llvm tool.

• The goal is to learn and build a small compiler which will be easy to extend with new features later on.
• This compiler is built in small steps over time.

Language

Kaleido is the language we are gonna make the compiler for. This language will have support for:

• defining functions
• conditionals
• math
• loops
• user defined operators
• JIT compilation

Kaleido also has support for calling standard library functions from llvm.

Datatypes in Kaleido

64-bit floating point number is the only datatype in kaleido. So this language does'nt require type declarations. In JS this is just the number type, so we can implement numbers in kaleido by storing them in JS number types.

Sample code in Kaleido

# Compute the x'th fibonacci number.
def fib(x)
  if x < 3 then
    1
  else
    fib(x-1)+fib(x-2)

# This expression will compute the 40th number.
fib(40)
