Did a port of busybox bzip2 compression code to plain and simple C99, and cproc/qbe gives me 70-80% of gcc (13.2.0) speed on amd zen2 (tinycc generated machine code is 2 times slower than gcc, but it is really simple and clean assembly code... so it will have its use cases...).

Namely, the combo of cproc/qbe + custom assembly would be the perfect toolchain for a lean open source stack with more than decent performance. Yeah, but we have still people missing out why c++ is so much toxic...
