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 x86_64 (when probing 32bit applications). Produces an error on other architectures.
