Emulated 64-bit atomic support for > functionally challenged 32-bit architectures (e.g. PPC32). Relaxed memory > model for atomic operations, this enhances performance on weakly ordered > architectures (e.g. most RISC). Use GCC __atomic builtins (previously > __sync builtins). Added missing atomic_add_u32, atomic_sub_u32 and > atomic_sub_64 operations. Removed 32- and 64-bit cmpset operations. Made > some 64-bit operations (e.g. load, store) atomic on 32-bit architectures. > odp_generator.c: updated to use odp_atomic.h functins with atomic types. > odp_spin_internal.h: removed odp_mem_barrier() which is a compiler only > barrier and basically useless and dangerous on all weakly ordered > architectures. > odp_barrier.c: updated to use odp_atomic.h types and functions. Made > the wrap-around atomic. Restored a missing line that was lost to a later > patch. > odp_buffer.c: updated to use odp_atomic.h functions (ref_count). > odp_ring.c: added missing release barriers. Updated to use GCC __atomic > cmpset facility (temporary fix). > odp_rwlock.c: updated to use odp_atomic.h. Updated to use GCC __atomic > facilities (temporary fix). > odp_ticketlock.c: updated to use odp_atomic.h. Updated to use GCC __atomic > facilities (temporary fix). Added missing barrier in ticketlock_lock(). > odp_atomic_test.c: update to conform to latest odp_atomic.h syntax. Added > usage of odp_barrier_t instead of home grown thread barrier.
