New and Noteworthy: Universal binaries may have to be re-compiled with Intel's tools to take advantage of Core Duo
Universal binaries may have to be re-compiled with Intel's tools to take advantage of Core Duo A ZDNN article indicates that applications converted to Universal Binaries may need to be re-compiled with Intel's newly released Xcode-integrated developer tools in order to take full advantage of the Core Duo chip. "One drawback of using the new tools may be that they don't support Objective C, which many Mac applications will be written in. Objective C is considered to be the native language for Mac OS X, and before version 1.5 there was little support for C in Xcode. Intel has no plans to support Objective C, so existing developers will almost certainly have to modify their applications to take advantage of Intel's dual-core processors. Mac developers also face different vector instruction sets in the two architectures: Altivec in the PowerPC and MMX/SSE in the Intel architecture. While the two instruction sets perform the same operations in general, the precise instructions are different. Reinders said that unless you've written directly to the hardware, the transition should be straightforward." More.
