Remove the `q' suffix on x86-64 atomic instructions. |
| 22 |
|
| 23 |
We don't need the `q' suffix on x86_64 atomic instructions for AO_t, |
| 24 |
which is defined as "unsigned long". "unsigned long" is 32bit for x32 |
| 25 |
and 64bit for x86-64. The register operand in x86-64 atomic instructions |
| 26 |
is sufficient to properly determine the register size. |
