For example, a <code>or</code> instruction with an immediate larger than 16-bits

will be expanded into two instructions. This is a very undesirable feature to
|
||
|
|
rely on, so this flag can help detect any code where it happens. One
|
||
|
|
use of it, for instance, has been to find and eliminate any place
|

|

where <code>gcc</code> may emit these pseudo-instructions.
