Hi,
in, PR 79579, early inliner creates ipa_node_params_sum which is then
tested by ipa_prop_write_jump_functions to figure out whether there
has been anything to stream out when there is not.
The following patch improves the test - when there are no jump
function, there is no point in streaming jump functions or any ipa-cp
info in general.
Bootstrapped and tested on x86_64-linux, I will commit it momentarily
as obvious.
Thanks,
Martin
