--- Comment #2 from ktkachov at gcc dot gnu.org ---
The assert triggering is:
enum rtx_code inv_cond_code
= reversed_comparison_code (cond, insn);
/* We should be able to reverse all conditions. */
gcc_assert (inv_cond_code != UNKNOWN);
865257c447cc50f5819e9b53da83145f3c36c305 had recent changes in that area
