Are there any Objective-C wizards out there who could review a few conceptual and practical issues I have returning values from objc_msgSend and its friends?
I've just released Rococoa, a generic replacement for the Cocoa-Java bridge, under LGPL. Some things do not work as expected on PPC. I know I really need to understand how objc_msgSend works, but cannot find a complete discussion anywhere. In short, my questions are * If both objc_msgSend_stret and objc_msgSend hack the stack to return different sized return values, why are there 2 functions? * Should I call objc_msgSend_stret when returning longs on PPC? * Do I really need to call objc_msgSend_fpret for floating point on Intel? In long, my understanding of the issue is set out here: https://rococoa.dev.java.net/objc_msgSend.html If anyone could spare some time reading this document and putting me straight, you'd be helping an up-and-coming open-source project. It might even be tax-deductible.
