--- Comment #8 from tbsaunde at gcc dot gnu.org --- Author: tbsaunde Date: Tue Feb 10 14:49:07 2015 New Revision: 220585 URL: https://gcc.gnu.org/viewcvs?rev=220585&root=gcc&view=rev Log: cap frequency in make_forwarder_block In the testcase the block with problematic frequency has to incoming edges. Each edge has probability 1. The first edge's source bb has frequency 873/10000, and the second has a frequency of 9409/10000. So at least one of those is slightly high probably from some sort of rounding issue related to fixed point, but in any case make_forwarder_block should not create basic blocks with frequency greater than BB_FREQ_MAX. gcc/ PR tree-optimization/64326 * cfghooks.c (make_forwarder_block): Cap frequency of created basic block. Added: trunk/gcc/testsuite/gcc.dg/torture/pr64326.c Modified: trunk/gcc/ChangeLog trunk/gcc/cfghooks.c
