7.65 '.nops SIZE[, CONTROL]'
============================
This directive emits SIZE bytes filled with no-op instructions. SIZE is
absolute expression, which must be a positve value. CONTROL controls
how no-op instructions should be generated. If the comma and CONTROL
are omitted, CONTROL is assumed to be zero.
Note: For Intel 80386 and AMD x86-64 targets, CONTROL specifies the
size limit of a no-op instruction. The valid values of CONTROL 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.
