| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | gcc: Add support for label attributes and "unavailable" attribute. 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++. Obtained from: Apple GCC 4.2 - 5531

| | | | | | | | | | | | | | | | | | | | | original intent, but the functionality wasn't implemented until after gcc 4.2 was released. However, if you compiled a program that would behave differently before and after this change, gcc 4.2 would have warned you; hence, everything currently in the base system is unaffected by this change. This patch also adds additional warnings about certain inline function-related bogosity, e.g., using a static non-const local variable in an inline function. These changes were merged from a snapshot of gcc mainline from March 2007, prior to the GPLv3 switch. I then ran the regression test suite from a more recent gcc snapshot and fixed the important bugs it found. I also squelched the following warning unless -pedantic is specified: foo is static but used in inline function bar which is not static This is consistent with LLVM's behavior, but not consistent with gcc 4.3.

non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.
