| <var>size</var> is absolute expression, which must be a positve value. |
| <var>control</var> controls how no-op instructions should be generated. If |
| the comma and <var>control</var> are omitted, <var>control</var> is assumed to be |
| zero. |
| |
| <p>Note: For Intel 80386 and AMD x86-64 targets, <var>control</var> specifies |
| the size limit of a no-op instruction. The valid values of <var>control</var> |
| are between 0 and 4 in 16-bit mode, between 0 and 7 when tuning for |
| older processors in 32-bit mode, between 0 and 11 in 64-bit mode or when |
| tuning for newer processors in 32-bit mode. When 0 is used, the no-op |
| instruction size limit is set to the maximum supported size. |
