--- Comment #3 from Yuri Rumyantsev <ysrumyan at gmail dot com> ---
A check that stmt-bb belongs to loop is missed in is_cond_scalar_reduction, if
we add the following lines
if (gimple_code (stmt) != GIMPLE_ASSIGN
|| gimple_has_volatile_ops (stmt))
return false;
+
+ if (!flow_bb_inside_loop_p (loop, gimple_bb (stmt)))
+ return false;
test will be compiled successfully.
I will prepare a patch after required testing completion.
