- <p>This directive emits no-op instructions. It is specific to the Intel 80386 and
- AMD x86-64 targets. It takes a <var>size</var> argument and generates <var>size</var>
- bytes of no-op instructions. <var>size</var> must be absolute and positive. These
- bytes do not affect the generation of DWARF debug line information.
- </p>
- <p>The optional <var>control</var> argument specifies a size limit for a single no-op
- instruction. If not provided then a value of 0 is assumed. 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.
