FUNCTION::REGPARM

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.
