* 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. Obtained from: OpenBSD (CVS rev 1.4) MFC after: 1 week
* gcc: define __block when block support is enabledpfg2014-04-041-1/+4
| | | | | | | | | | | This mimics the behaviour in clang and lets us build cleanly the libdispatch port on platforms where the base gcc is still the default compiler. Bump __FreeBSD_version for ports. Tested by: theraven MFC after: 3 days

* Upgrade our copy of llvm/clang to 3.4 release. This version supportsdim2014-02-162-3/+3
| | | | | | | | | | | | | | | | | all of the features in the current working draft of the upcoming C++ standard, provisionally named C++1y. The code generator's performance is greatly increased, and the loop auto-vectorizer is now enabled at -Os and -O2 in addition to -O3. The PowerPC backend has made several major improvements to code generation quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ backends have all seen major feature work. Release notes for llvm and clang can be found here: <http://llvm.org/releases/3.4/docs/ReleaseNotes.html> <http://llvm.org/releases/3.4/tools/clang/docs/ReleaseNotes.html> MFC after: 1 month
* gcc: Add support for -Wmissing-prototypes in C++pfg2014-01-263-3/+13
| | | | | | | | | Support for warnings about missing prototypes in C++ was added by Apple GCC (Radar 6261539). Most of the code crept into r260311 so it felt natural to make use of it. Obtained from: Apple GCC - 5646 MFC after: 5 days
* gcc: Drop useless objc change from r260311.pfg2014-01-172-39/+0
| | | | | | | | | | | | Among some of the objc changes from Apple that crept into r260311, Radar 5355344 is incomplete and is not used since we don't carry ObjC in the base system. The dead code seems to have caused issues in some Tinderboxes so get rid of it altogether. Reported by: luigi MFC after: 9 days
* Fix gcc with EABI on big-endian ARM by setting the endian correctly.andrew2014-01-121-0/+3
| | | | | | Without this gcc would generate byte loads for a little-endian core. MFC after: 1 week
* Fix optimization bug.pfg2014-01-061-6/+11
| | | | | | | | | | | | | GCC-PR rtl-optimization/34628 * combine.c (try_combine): Stop and undo after the first combination if an autoincrement side-effect on the first insn has effectively been lost. The issue was detected in OpenBSD but their fix was not very good. Huge thanks to the upstream author, Eric Botcazou, for permitting the use of this patch under GPLv2. MFC after: 5 days
* gcc: backport some fixes from llvm-gccpfg2014-01-054-152/+196
| | | | | | | | | | | | | | | | | | | | llvm-gcc backported some patches from gcc trunk: http://gcc.gnu.org/ml/gcc-cvs/2007-05/msg00662.html http://gcc.gnu.org/ml/gcc-cvs/2007-07/msg00019.html http://gcc.gnu.org/ml/gcc-cvs/2007-08/msg00240.html http://gcc.gnu.org/ml/gcc-cvs/2007-08/msg00493.html The first two were always GPL2. The last two were added after the GPL3 transition, but were written by aaw@google.com and Rafael Espíndola got permission to relicense them under the GPL2 for inclusion in llvm-gcc. This fixes GCC-PR c++/31749 Obtained from: llvm-gcc (rev. 75463; GPLv2) MFC after: 2 weeks
* 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.

* Revert r260073; small diff reduction wrt gcc43 and Apple GCC.pfg2014-01-028-84/+41
| | | | | | | | Unfortunately this causes ICE on powerpc and sparc64. Reducing these differences against upstream is not important anymore so hopefully I have finished breaking the compiler occasionally.
* gcc: Fix issue with "unavailable" attribute.pfg2013-12-301-1/+3

| | | | | Obtained from: gcc 4.3 (rev. 121464, 122528, 124106; GPLv2) MFC after: 3 weeks
* 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
