I'm very tempted to use the new 64-bit Objective-C ABI in my next project. Primarily because of the improved interoperability with C++ destructors, that are now called when unwinding Objective-C exceptions and should make it possible to use RAII designs in Objective-C++ programs.
If I were to require the use of the 64-bit ABI in my next project, which mac models would the application run on? And is it possible to detect at runtime if I'm running the old 32-bit ABI or the new 64-bit to enable a fallback on non-64-bit models? Best Regards, Påhl Melin >From the "Objective-C Runtime Release Notes for Mac OS X v10.5" : "In 64-bit, C++ exceptions and Objective-C exceptions are interoperable. In particular, C++ destructors and Objective-C @finally blocks are honored when unwinding any exception, and default catch clauses—catch (...) and @catch (...)—are able to catch and re-throw any exception." _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
