Sericum

Compiler Infrastructure influenced by LLVM written in Rust

Do not expect too much stuff!

To Do

• Implement basic block parameters
• Make it possible to generate code for multiple targets without rebuilding sericum itself
• Verify IR
• More optimizations for IR
• Support returning struct as value
• Write documents

Build

Requirement: Rust nightly

cargo test           --features x86_64                          # build for x86_64
cargo test brainfuxk --features x86_64 --release -- --nocapture # this is fun. just try it.
cargo test           --features aarch64                         # build for aarch64. a few features are implemented.
cargo test           --features riscv64                         # currently doesn't work. need help.

Example

• Generate a function which calculates a fibonacci number

cargo test demo --features $ARCH -- --nocapture # $ARCH is x86_64 or aarch64

• Useful macro is available to describe IR

let fibo = sericum_ir!(m; define [i32] f [(i32)] {
    entry:
        cond = icmp le (%arg.0), (i32 2);
        br (%cond) l1, l2;
    l1:
        ret (i32 1);
    l2:
        a1 = sub (%arg.0), (i32 1);
        r1 = call f [(%a1)];
        a2 = sub (%arg.0), (i32 2);
        r2 = call f [(%a2)];
        r3 = add (%r1), (%r2);
        ret (%r3);
});

Make your own language using sericum as backend

./minilang and ./sericumcc may help you.
