My compile times went down by a factor of 8 for a large project! The new C compiler uses the same basic code generator as the MPW pascal compiler, so its level of optimization is reasonably high, though certainly not state of the art. Benchmarks have shown that the new compiler is slightly faster on some programs, and slightly slower on others. By the way, I'm pretty sure the Green Hills Compiler doesn't contain any PCC code. It was written from scratch (in Pascal!), many years ago. Andrew Shebanow MacDTS
