In libobjc/:
2010-10-17 Nicola Pero <nicola.pero@meta-innovation.com>
* init.c (objc_send_load): Do not wait for NXConstantString to be
registered before executing +load. There is no point if
-fconstant-string-class=xxx is used when compiling all modules,
as is the case for almost all users.
* linking.m (__objc_linking): Do not try to forcefully link in
NXConstantString.
In gcc/:
2010-10-17 Nicola Pero <nicola.pero@meta-innovation.com>
* doc/objc.texi (What you can and what you cannot do in +load):
Document that sending messages to constant string objects in +load
is not guaranteed to work.
