re PR middle-end/43866 (wrong code with -fbounds-check -funswitch-loops)
PR middle-end/43866
* tree-ssa-loop-unswitch.c (tree_may_unswitch_on): If stmt is always
true or always false, return NULL_TREE.
(tree_unswitch_single_loop): Optimize conditions even when reaching
max-unswitch-level parameter. If num > 0, optimize first all conditions
using entry checks, then do still reachable block discovery and consider
only conditions in still reachable basic blocks in the loop.
* gfortran.dg/pr43866.f90: New test.
