Dormouse

A C-Like statically typed programming language.

Why another one?

• For me to learn

Running

Download repo, install Go. go run . PATH_TO_FILE. As easy as it gets.

How it works

1. Lexing, see lex
2. Pratt parser, see parse
3. Generate assembly for the system, see codegen
4. Compile assembly with default system assembler, see codegen.

Features

• Parsing and lexing for a good chunk of the syntax.
• Codegen for x86_64 and aarch64.

Command Line Parameters

• -d - debug print
• -a - target architecture. supports x86_64, and aarch64 without a couple features of x86_64.
• -v - verbose
• -o - file name of output file which will be placed in out/ARCHITECTURE

SSA

To see output, view out/ssa. An example program is shown below.

Before optimizations:

func main(int v1, int v2) int {
    int v3 = 7 + v1
    int v4 = 8 + v2
    int v5 = v3 + v4
    return v5
}

After optimizations:

func main(int v1, int v2) int {
    v5 = 15 + v1 + v2
    return v5
}
