Revision: 172 http://trac.macosforge.org/projects/libdispatch/changeset/172 Author: robert@fledge.watson.org Date: 2009-12-15 00:44:31 -0800 (Tue, 15 Dec 2009) Log Message: ----------- When testing -lBlocksRuntime requirement, build blocks excerpt with -O0. As the clang optimizer improves, it becomes better at optimizing out dead code, such as our sample blocks use, which prevents the linkage dependency from working properly.
