Anders Magnusson's BSD-licensed pcc compiler has been imported into NetBSD's pkgsrc and OpenBSD's src tree. Anders wrote to NetBSD's tech-toolchain list: "It is not yet bug-free, but it can compile the i386 userspace. The big benefit of it is that it is fast, 5-10 times faster than gcc, while still producing reasonable code. The only optimization added so far is a multiple-register-class graph-coloring register allocator, which may be one of the best register allocators today. Conversion to SSA format is also implemented, but not yet the phi function. Not too difficult though, after that strength reduction is high on the list."

But what is the practical need for such a compiler? You can use gcc to compile BSD-licensed software (heck, even proprietary software!) with no licensing problems.
