NAME
       function::regparm - Specify regparm value used to compile function

SYNOPSIS
           regparm(n:long)

ARGUMENTS
       n
           original regparm value

DESCRIPTION
       Call this function with argument n before accessing function arguments
       using the *arg function is the function was build with the gcc
       -mregparm=n option.

       (The i386 kernel is built with \-mregparm=3, so systemtap considers
       regparm(3) the default for kernel functions on that architecture.) Only
       valid on i386 and x8664 (when probing 32bit applications). Produces an
       error on other architectures.
