Commit Message

Enable CAS for byte and short on RISC-V

Issue #31 (libatomic_ops).

At least for gcc-7.2.0 does not define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_1
and __GCC_HAVE_SYNC_COMPARE_AND_SWAP_2 macros but, nonetheless, all the
provided CAS operations are lock-free (except for double-word).

* src/Makefile.am (nobase_private_HEADERS): Add gcc/riscv.h entry.
* src/atomic_ops.h [__GNUC__ && !AO_USE_PTHREAD_DEFS
&& !__INTEL_COMPILER && __riscv]: Include gcc/riscv.h file.
* src/atomic_ops/sysdeps/gcc/riscv.h: New file (include generic.h).
* src/atomic_ops/sysdeps/gcc/riscv.h (AO_GCC_FORCE_HAVE_CAS): Define
before include generic.h (and undefined at the end of file); add
comment about double-word operations.
