Mac OS X Built For CISC, Not RISC

WCityMike writes "One of the programmers at Unsanity, maker of haxies, recently posted a rather shocking relevation on the company's weblog. He says that Mac OS X's Mach-O runtime ABI (Application Binary Interface) comes from a NeXTStep design for 68K processorts, and is not designed for the PowerPC architechture. Had they used the latter, things would have been approximately 10-12 percent faster. And supposedly, they can't fix it now without breaking all existing applications." The developer mentions there are workarounds in the newest GCC, but only for newly compiled programs.
