New Revision: 138865
URL: http://llvm.org/viewvc/llvm-project?rev=138865&view=rev
Log:
objective-c - This patch buffers method implementations
and does the Sema on their body after the entire
class/category @implementation is seen. This change allows messaging
of forward private methods, as well as, access to
synthesized ivars of properties with foward synthesize
declarations; among others. In effect, this patch removes
several restrictions placed on objective-c due to in-place
semantics processing of methods.
This is part of // rdar://8843851.
