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.
