In libobjc/:
2010-10-15 Nicola Pero <nicola.pero@meta-innovation.com>
* Protocol.m: Include objc/runtime.h and
objc-private/module-abi-8.h instead of objc/objc-api.h. Do not
repeat Protocol's instance variables.
(struct objc_method_description_list): Do not define here.
([-conformsTo:]): Reimplemented on top of protocol_conformsTo().
([descriptionForInstanceMethod:]): Use sel_isEqual() to compare
selectors directly instead of getting names and then using strcmp.
([descriptionForClassMethod:]): Same change.
([-isEqual:]): Reimplemented on top of protocol_isEqual().
* protocols.c (protocol_getMethodDescription): Use sel_isEqual()
to compare selectors directly instead of getting names and then
using strcmp.
* objc/Protocol.h: Updated comments.
