limit += limit * PARAM_VALUE (PARAM_LARGE_FUNCTION_GROWTH) / 100;
/* Check the size after inlining against the function limits. But allow
the function to shrink if it went over the limits by forced inlining. */
newsize = cgraph_estimate_size_after_inlining (times, to, what);

{
this allows unbounded growth based on PARAM_LARGE_FUNCTION_GROWTH, ignoring
PARAM_LARGE_FUNCTION_INSNS. Shouldn't we at least limit
/* When inlining large function body called once into small function,
take the inlined function as base for limiting the growth. */
if (inline_summary (to)->self_size > inline_summary(what)->self_size)
limit = inline_summary (to)->self_size;
else
limit = inline_summary (what)->self_size;
limit += limit * PARAM_VALUE (PARAM_LARGE_FUNCTION_GROWTH) / 100;
so that limit is at most PARM_LARGE_FUNCTION_INSNS * PARM_LARGE_FUNCTION_GROWTH
/ 100?
