We knew since January that PCC v1.0 was approaching, but yesterday -- as not an April Fools' Joke -- it was finally released.
We have benchmarked it a bit in the past, but now that 1.0.0 is out there will be new tests conducted in time. The Portable C Compiler is designed to be much faster than GCC.
The last pre-1.0 release of PCC, v0.9.9, arrived three years ago.
This open-source C compiler can be downloaded from the project web-site.
