I tried both llvm-gcc and CLANG. I did not have any trouble getting them to work for my 64 bit chess program.
I didn't try too hard, but neither is producing executables as fast as gcc. llvm-gcc is the slowest about 20% slower than gcc and clang is only a little slower than gcc. Since I developed with gcc it is very likely that the program and the way I write code is "tuned" to work well with gcc. Perhaps I will try this with the GO program, which is not heavily optimized. I grabbed and compiled the latest llvm and clang - so I cannot be accused of using outdated versions. And I didn't use the debug versions either. But I will keep my eye on llvm and clang. - Don 2009/9/6 Mark Boon <tesujisoftw...@gmail.com> > > On Sep 5, 2009, at 4:41 AM, terry mcintyre wrote: > > Found an interesting article on Snow Leopard at Ars Technica ... 20-some > pages. > > http://arstechnica.com/apple/reviews/2009/08/mac-os-x-10-6.ars > > Of interest to Computer Go programmers: the addition of blocks to C, which > allow closures and other fun stuff, much like Lisp.
