An optimizing compiler of SysY, a subset of C. Supported targets are armv7 and risc-v32. (To be accurate, armv7ve and rv32im.)
SysY is the language used by the Collegiate Student System Capability Challenge (Compiler Track) 2021, an compiler contest in China. (contest homepage)
For SysY specification (in Chinese), runtime, and testcases, see here.
