* Fix compilation of this macro under gcc-4.9 for MIPS32.adrian2015-06-181-5/+5
| | | | | | | | | | | Some point after gcc-4.2 the MIPS inline assembly restrictions changed - =h (hi register) disappeared from the list of restrictions and can no longer be used. So, until someone requires an assembly version of this function, just use a non-assembly version and let the compiler sort it out. Suggested by: kan

* gcc: fix strict alignment.pfg2014-05-021-1/+1
| | | | | | | | | | | | | | | From the OpenBSD log: x86-64 ABI requires arrays greater than 16 bytes to be aligned to 16byte boundary. However, GCC 16-byte aligns arrays of >=16 BITS, not BYTES. This diff improves bug detectability for code which has local arrays of [16 .. 127] bits: in those cases SSP will now detect even 1-byte overflows.

* gcc: Add support for Apple's Block extensionpfg2014-01-0565-404/+10016
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 that __block is not actually a keyword, but a macro. There will be workaround for this issue in a near 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.

* gcc: Add support for label attributes and "unavailable" attribute.pfg2013-12-2829-161/+753
| | | | | | | | | | | | | | | Apple GCC has extensions to support for both label attributes and an "unavailable" attribute. These are critical for objc but are also useful in regular C/C++. Apparently at least the label attributes might have found their way to upstream GCC but the code doesn't seem available on the GPLv2 tree so we are taking the code directly from Apple. To make this clearer we are preserving the annoying "APPLE LOCAL" tags and the ChangeLogs when they are available. Obtained from: Apple GCC 4.2 - 5531 MFC after: 3 weeks
