The soft-float O32, N32, and N64 support has been committed upstream. The hard-float changes are still in review upstream. Enable LLVM_LIBUNWIND on mips when building with a suitable (C+11-capable) toolchain. This has been tested with external GCC for all ABIs and O32 and N64 with clang.

This is compatible with current GCC 6.1 compiler. RISC-V is extensible ISA and the idea here is to have built-in define per each extension, so together with __riscv we will have some subset of these as well (depending on -march string passed to compiler): __riscv_compressed __riscv_atomic __riscv_mul __riscv_div __riscv_muldiv __riscv_fdiv __riscv_fsqrt __riscv_float_abi_soft __riscv_float_abi_single __riscv_float_abi_double __riscv_cmodel_medlow __riscv_cmodel_medany __riscv_cmodel_pic __riscv_xlen Reviewed by: ngie Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D11901 2017-01-07T14:40:58Z Ed Maste emaste@FreeBSD.org 2017-01-07T14:40:58Z urn:sha1:d4cd50b494d679d68851a8a02e22cd9a7cd11f7b Reported by: vangyzen Reviewed by: kib MFC after: 1 week Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D9075 2016-12-21T14:06:44Z Ed Maste emaste@FreeBSD.org 2016-12-21T14:06:44Z urn:sha1:77ac8927fda49722185dab219365be31daed8872 The libgcc __register_frame and __deregister_frame functions take a pointer to a set of FDE/CIEs, terminated by an entry where length is 0. In Apple's libunwind implementation the pointer is taken to be to a single FDE. I suspect this was just an Apple bug, compensated by Apple- specific code in LLVM. See lib/ExecutionEngine/RuntimeDyld/RTDyldMemoryManager.cpp and http://lists.llvm.org/pipermail/llvm-dev/2013-April/061737.html for more detail. This change is based on the LLVM RTDyldMemoryManager.cpp. It should later be changed to be alignment-safe.
