v6:
- rename __QEMU_THREAD_COMMON_H__ to QEMU_THREAD_COMMON_H
- collect r-bs for Emilio
v5:
- init file/line [Emilio]
v4:
- cherrypick Emilio's patch to add "-m" parameter to atomic_add-bench
tool.
- use inline functions [Emilio]
Micro benchmark result on "taskset -c 0 atomic_add-bench -m":
|--------+---------------------+------------------------|
| | with --enable-debug | without --enable-debug |
|--------+---------------------+------------------------|
| Before | 20 Mops/s | 34 Mops/s |
| After | 18 Mops/s | 34 Mops/s |
|--------+---------------------+------------------------|
Please review. Thanks.
