This patch switches all the testcases in the ObjC/ObjC++ testsuite to use the Modern Objective-C runtime API when executing with the GNU runtime. This will allow me to complete removing the Traditional Objective-C runtime API from libobjc. :-) There should be no changes in testsuite results, with the exception that during the reorganization I managed to enable all the objc/execute/bf-*.m testcases for the recent NeXT runtime, and an update of the forward-1.m testcase makes it XPASS on Apple (that's not really important though as all the forwarding and corresponding testing needs a rework). So, there should be more successes when executing the testsuite on an Apple. :-) The patch is large and very tedious (as you'd expect). The existing runtime compatibility layer was based upon mapping all APIs to the Traditional Objective-C runtime API, which is precisely the one that we are removing. So I wrote a new, simpler runtime compatibility layer that maps everything to the Modern Objective-C runtime API, and then proceeded to update all the testcases to use it instead of the old one, and use the Modern API as the normal API instead of the Traditional one. The new layer is much simpler because it's the native API of both the Modern GNU and NeXT runtimes; the only case that actually needs any mappings now is the case of older NeXT runtimes (pre-OS X 10.5), and even then most functions are identical. The new layer currently includes only functions used in at least a testcase, which are few. I don't see the point in spending time writing a full compatibility layer (also considering that the older NeXT runtime API was dropped by Apple 4 years ago, and it will be less and less relevant as the years go by). Another simplification I introduced is a new, very simple root class to use in testcases instead of Object. It's called TestsuiteObject. The problem with Object is that each runtime provides a different subset of the class, and newer runtimes are making it more and more minimal possibly with the ultimate aim of dropping it. Rather than write code to try figure out which subset of Object is available (if any) in the current runtime, and keep it up-to-date as runtimes change, it's simpler to just write a minimal root class for the testsuite and use it; the same code then works with all runtimes, and is independent of whether Object will stay or disappear in the future. I hope that this will give us a stable testcase base for the future, with fewer dependencies on the runtime details. :-) I left a few testcases using Object, though, to make sure it gets at least some minimal testing. I picked a few ones where there is no need for runtime-dependent code or checks (to keep things simple). I tested this on GNU/Linux i686, and on Apple 10.6.7 64-bit. That tests both the GNU runtime and a recent NeXT runtime. I'd like to test with an older NeXT runtime, but I don't have any access to an Apple machine with Mac OS X < 10.5. If anyone can test that and supply test results (objc.log / obj-c++.log), I'll be happy to address any problems (I'd expect some, basing on the fact I couldn't test that at all, but they should be shallow/easy, such as a typo or a missing prototype). To my delight, on my local tree I tested purging completely the Traditional Objective-C runtime API from the GNU runtime, and with this patch the testsuite still runs and passes all the tests for the GNU runtime (yes!!). That means that while this patch was a tedious interminable pain to produce, the road ahead is finally open for the GNU Objective-C runtime to go fully "Modern". :-) OK to commit ?
