ericwa	317e951b0c	libobjc2: some changes needed to build on OS X. CDECL macro to prefix symbol names in assembly code with an underscore, macros to omit the .type and .section derictives which are unsupported on OS X, and also a linker flag to make weak symbols work	13 years ago
theraven	d80689e3e4	Remove the test for whether the uninstalled dtable is present from objc_msgSend(). If the class does have the uninstalled dtable, then every method will be the nil slot and so, after navigating the dtable we will discover that it is nil and go into the slow path. The cost of this change is a slight slowdown in the first message sent to every class. The benefit is that every subsequent message send needs one fewer memory access and one fewer conditional jump.	13 years ago
