* MFC 264190:ian2014-05-171-1/+1
| | | | | Mark __fixdfdi/__aeabi_d2lz with COMPILER_RT_ABI so it uses the correct calling convention for __aeabi_* functions.
* MFC r262613:dim2014-03-2636-73/+77
| | | | | | | | | | | | | | | | | | | | | Merge the projects/clang-sparc64 branch back to head. This brings in several updates from the llvm and clang trunks to make the sparc64 backend fully functional. Apart from one patch to sys/sparc64/include/pcpu.h which is still under discussion, this makes it possible to let clang fully build world and kernel for sparc64. Any assistance with testing this on actual sparc64 hardware is greatly appreciated, as there will unavoidably be bugs left. Many thanks go to Roman Divacky for his upstream work on getting the sparc64 backend into shape. MFC r262985: Repair a few minor mismerges from r262261 in the clang-sparc64 project branch. This is also to minimize differences with upstream.

* Import compiler-rt r172839.andrew2013-01-187-5/+64
| | | | | This brings in __aeabi_lcmp and __aeabi_ulcmp. It also fixes the spelling of __aeabi_f2lz. Both changes originated on the arm_eabi project branch.
* Import compiler-rt r160957.andrew2012-08-0887-124/+665
| | | | | | This is mostly a no-op other than for ARM where it adds missing __aeabi_mem* and __aeabi_*divmod functions. Even on ARM these will remain unused until the rest of the ARM EABI code is merged.
* Regenerate after r235388.marius2012-05-132-30/+24

* - Get rid of debugging support in order to get rid of the V8-specific Cmarius2012-05-131-20/+18
| | | | | | | | | | | compiler frame size used there so this whole thing is V8/V9-agnostic. - Use 32-bit function alignment as GCC does when using UltraSPARC I or higher optimizations. - Don't waste delay slots when possible. Unfortunately, this still doesn't make libcompiler_rt a viable replacement for libgcc on sparc64 though as once installed instead, buildworld times increase by nearly 60% (which isn't related to these assembler functions).
* Add SPARC64 version of div/mod written in assembly.ed2012-01-126-0/+924
| | | | | | | | This version is similar to the code shipped with libgcc. It is based on the code from the SPARC64 architecture manual, provided without any restrictions. Tested by: flo@
* Add a workaround to prevent endless recursion in compiler-rt.ed2012-01-121-0/+20
| | | | | | | | | | | | | | | SPARC and MIPS CPUs don't have special instructions to count leading/trailing zeroes. The compiler-rt library provides fallback rountines for these. The 64-bit routines, __clzdi2 and __ctzdi2, are implemented as simple wrappers around the compiler built-in __builtin_clz(), assuming these will expand to either 32-bit CPU instructions or calls to __clzsi2 and __ctzsi2. Unfortunately, our GCC 4.2 probably thinks that because the operand is stored in a 64-bit register, it might just be a better idea to invoke its 64-bit equivalent, simply resulting into endless recursion. Fix this by defining __builtin_clz and __builtin_ctz to __clzsi2 and __ctzsi2 explicitly.
* Import compiler-rt r147467.ed2012-01-032-3/+3
| | | | | The compiler-rt shipped with FreeBSD is now based on unmodified upstream sources.
* Upgrade libcompiler_rt to upstream revision 147390.ed2011-12-31149-897/+882
| | | | | | | | | This version of libcompiler_rt adds support for __mulo[sdt]i4(), which computes a multiply and its overflow flag. There are also a lot of cleanup fixes to headers that don't really affect us. Updating to this revision should make it a bit easier to contribute changes back to the LLVM developers.
* Upgrade libcompiler_rt from revision 117047 to 132478.ed2011-06-03201-536/+1346
| | | | | | | | | | | | | | | | | | | | | | It seems there have only been a small amount to the compiler-rt source code in the mean time. I'd rather have the code in sync as much as possible by the time we release 9.0. Changes: - The libcompiler_rt library is now dual licensed under both the University of Illinois "BSD-Like" license and the MIT license. - Our local modifications for using .hidden instead of .private_extern have been upstreamed, meaning our changes to lib/assembly.h can now be reverted. - A possible endless recursion in __modsi3() has been fixed. - Support for ARM EABI has been added, but it has no effect on FreeBSD (yet). - The functions __udivmodsi4 and __divmodsi4 have been added. Requested by: many, including bf@ and Pedro Giffuni
* Set symbol visibility to hidden.ed2010-11-111-3/+3
| | | | | | | Not doing so may cause all sorts of random libraries to expose libcompiler_rt's functions, which should of course not be done. Discussed with: kan, kib
* Import libcompiler_rt into HEAD and add Makefiles.ed2010-11-11207-0/+12384
