The relevant code is in opts.c:
if (optimize_size)
{
/* Inlining of very small functions usually reduces total size. */
set_param_value ("max-inline-insns-single", 5);
set_param_value ("max-inline-insns-auto", 5);
flag_inline_functions = 1;
It was added here:

Inlining has changed considerably since then, and it is possible that
these parameter values are no longer appropriate. The reports at the
time indicate space savings.
