@('0') but on Darwin machines, it is @('3'). The x86 model
currently supports syscall numbers for Linux and Darwin operating
systems only.</p>
<p>For the x86isa model, we define the syscall numbers based on the
contents of the @('os-info') field of the x86 state. Currently
supported values of this field are @(':linux') and @(':darwin'), with
@(':linux') being the default value. Note that the field @('os-info')
is meaningful only in the @(see app-view).</p>"
