Author: pfg Date: Sun Jan 26 19:49:54 2014 New Revision: 261188 URL: http://svnweb.freebsd.org/changeset/base/261188 Log: MFC r260311, r260831: gcc: Add support for Apple's Block extension Block objects [1] are a C-level syntactic and runtime feature. They are similar to standard C functions, but in addition to executable code they may also contain variable bindings to automatic (stack) or managed (heap) memory. A block can therefore maintain a set of state (data) that it can use to impact behavior when executed. This port is based on Apple's GCC 5646 with some bugfixes from Apple GCC 5666.3. It has some small differences with the support in clang, which remains the recommended compiler. Perhaps the most notable difference is that in GCC __block is not actually a keyword, but a macro. There may be workaround for this issue in the future. Other issues can be consulted in the clang documentation [2] For better compatiblity with Apple's GCC and llvm-gcc, some related fixes and features from Apple have been included. Support for the non-standard nested functions in GCC is now off by default. No effort was made to update the ObjC support since FreeBSD doesn't carry ObjC in the base system but some of the code crept in and was more difficult to remove than to adjust.
