Learn about SSYC

SSYC, full name slime SysY compiler, is a compiler for C-like language SysY.

Features

• Ease to use compiler driver
• Hand written frontend
• Strong typed IR in SSA form similar to LLVM-IR
• Minimal standard library for IO, debug and profiling
• Pretty assembly output

Installation

Requirement

Minimum requirements

• CMake >= 3.5
• C++ compiler supporting C++17 standard

Recommended configuration (for test, profiling and use of scripts)

• Git
• Clang >= 15.0.0
• 32-bit standard libraries for C/C++
• GTest
• nushell >= 0.78.0
• fd >= 8.5.3
• ripgrep >= 13.0.0
