RISC-V: Build Infastructure
This patch lays out the top-level orginazition of the RISC-V port. It contains all the Implies files as well as various other fragments of build infastructure for the RISC-V port. This contains the only change to a shared file: config.h.in. RISC-V is a family of base ISAs with optional extensions. The base ISAs are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but this port currently only supports RV64I based systems. Support for RISC-V lives in in sysdeps/riscv. In addition to these ISAs, our glibc port supports most of the currently-defined extensions: the A extension for atomics, the M extension for multiplication, the C extension for compressed instructions, and the F/D extensions for single/double precision IEEE floating-point. Most of these extensions are handled by GCC, but glibc defines various floating-point wrappers and emulation routines as well as some atomic wrappers. We support running glibc-based programs on Linux, the support for which lives in sysdeps/unix/sysv/linux/riscv. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/Implies: New file. * sysdeps/riscv/Makefile: Likewise. * sysdeps/riscv/configure: Likewise. * sysdeps/riscv/configure.ac: Likewise. * sysdeps/riscv/nptl/Makefile: Likewise. * sysdeps/riscv/preconfigure: Likewise. * sysdeps/riscv/rv64/Implies-after: Likewise. * sysdeps/riscv/rv64/rvd/Implies: Likewise. * sysdeps/riscv/rv64/rvf/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/Makefile: Likewise. * sysdeps/unix/sysv/linux/riscv/Versions: Likewise. * sysdeps/unix/sysv/linux/riscv/configure: Likewise. * sysdeps/unix/sysv/linux/riscv/configure.ac: Likewise. * sysdeps/unix/sysv/linux/riscv/ldd-rewrite.sed: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Makefile: Likewise. * sysdeps/unix/sysv/linux/riscv/shlib-versions: Likewise.
