Subject: [PATCH] df-problems.c (can_move_insns_across): Exit loop once we find
a non-fixed, non-global register.
* df-problems.c (can_move_insns_across): Exit loop once we
find a non-fixed, non-global register.
* ipa-pure-const.c (propagate_nothrow): Exit loop after
setting can_throw.
* omega.c (omega_eliminate_red): Break after setting red_found.
(omega_problem_has_red_equations): Similarly after setting found.
(omega_query_variable): Similarly after setting coupled.
* trans-decl.c (gfc_build_dummy_array_decl): Exit loop after
setting PACKED_PARTIAL.
