The comparison was incorrect when the counts weren't PRECISE.
For example, crossmodule-indir-call-topn-1.c was failing
with AutoFDO: when count_sum is 0 with quality AFDO,
count_sum > profile_count::zero() evaluates to true. Taking that
branch then leads to an assert in the call to to_sreal().
Tested on x86_64-pc-linux-gnu.
gcc/ChangeLog:
* ipa-cp.cc (good_cloning_opportunity_p): Fix profile count comparison.
ipa_node_params *info = ipa_node_params_sum->get (node);
int eval_threshold = opt_for_fn (node->decl, param_ipa_cp_eval_threshold);
- if (count_sum > profile_count::zero ())
+ if (count_sum.nonzero_p ())
{
- gcc_assert (base_count > profile_count::zero ());
+ gcc_assert (base_count.nonzero_p ());
sreal factor = count_sum.probability_in (base_count).to_sreal ();
sreal evaluation = (time_benefit * factor) / size_cost;
evaluation = incorporate_penalties (node, info, evaluation);
