* Add new PowerPC relocations to binutilsJustin Hibbits2014-12-1211-822/+1424
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: LLVM/Clang generates relocations that our binutils doesn't understand, but newer binutils does. I got permission from the author of a series of patches to relicense them as GPLv2 for use in FreeBSD. The upstream git hashes are: ac2df442ac7901f00af15b272fc48b594b433713 2b95367962dc14f69d3c338c4d54195266e2e169 102890f04c44b64cf5cef4588267dd9f24086ac7 b7fcf6f6bb53b5027e111107f5416769cb9a5798 1d483afedd5a628dc84fb58d1d570f79fdfbfa7b 90aecf7a80c1cefeb45fc10a6cd02c8338e34b4c 3a71aa26df2a372a58e9c11ef9ba51fd0e83320a 727fc41e077139570ea8b8ddfd6c546b2a55627c With the import of clang 3.5, and a few backported patches, we should be able to move powerpc and powerpc64 to clang-as-cc soon.

* Improve support for XSAVE with debuggers.John Baldwin2014-11-212-0/+3
| | | | | | | | | | | | | | | | | | | | | | - Dump an NT_X86_XSTATE note if XSAVE is in use. This note is designed to match what Linux does in that 1) it dumps the entire XSAVE area including the fxsave state, and 2) it stashes a copy of the current xsave mask in the unused padding between the fxsave state and the xstate header at the same location used by Linux. - Teach readelf() to recognize NT_X86_XSTATE notes. - Change PT_GET/SETXSTATE to take the entire XSAVE state instead of only the extra portion. This avoids having to always make two ptrace() calls to get or set the full XSAVE state. - Add a PT_GET_XSTATE_INFO which returns the length of the current XSTATE save area (so the size of the buffer needed for PT_GETXSTATE) and the current XSAVE mask (%xcr0).

* Rename elf*-powerpc into elf*-powerpc-freebsd in binutilsBaptiste Daroussin2014-10-105-3/+6
| | | | | | | | | | | | | | | | The powerpc support was the only supported architecture not prepending the elf format name with "-freebsd" in base this change makes it consistent with other architectures. On newer version of binutils the powerpc format is also prepended with "-freebsd". Also modify the kernel ldscripts in that regards.

We've been getting away without support for the sec extension because it's bogusly enabled even on arches where its presence is optional.

* Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental.Andrew Turner2014-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit. This is an optional coprocessors may not be present in all devices, however it appears to be in all current SoCs we support. armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too old to support this. Because of this there are a number of WITH/WITHOUT options that are unsupported and must be left as the default value. The options and their required value are: * WITH_ARM_EABI * WITHOUT_GCC * WITHOUT_GNUCXX In addition, without an external toolchain, the following need to be left as their default: * WITH_CLANG * WITH_CLANG_IS_CC As there is a different method of passing float and double values to functions the ABI is incompatible with existing armv6 binaries. To use this a full rebuild of world is required. Because no floating point values are passed into the kernel an armv6 kernel with VFP enabled will work with an armv6hf userland and vice versa.
