QBE – a new compiler back end

QBE aims to be a pure C embeddable backend that provides 70% of the performance of advanced compilers in 10% of the code. Its small size serves both its aspirations of correctness and our ability to understand, fix, and improve it. It also serves its users by providing trivial integration and great flexibility.

QBE is much smaller than TCC, c_count *.c in tinycc/ gives 25,000 lines containing code, in qbe/you get 5,400 lines. Comparing the "main logic of tcc" to QBE is nonsense, the "main logic" of tcc is a C parser, the "main logic" of QBE is a compiler backend, it simply does not make any sense to compare the two.
