re PR middle-end/25724 (Emits call to __cmpdi2 for long long comparison in switches)
PR middle-end/25724
* dojump.c (do_jump): Call do_compare_rtx_and_jump.
(do_jump_parts_zero_rtx): New function renamed from
do_jump_parts_equality_rtx. Made static. Add a mode argument.
(do_jump_parts_equality_rtx): New function split out from
do_jump_parts_equality. Old implementation renamed as above.
Call do_jump_parts_zero_rtx if either operand is zero.
(do_jump_parts_equality): Call do_jump_parts_equality_rtx to
do all of the heavy lifting.
(do_compare_rtx_and_jump): Handle multi-word comparisons by
calling either do_jump_by_parts_greater_rtx or
do_jump_by_parts_equality_rtx.
* expr.h (do_jump_by_parts_equality_rtx): Remove prototype.
* expmed.c (do_cmp_and_jump): Now multi-word optimization has
moved to do_compare_rtx_and_jump, call it directly.
* stmt.c (do_jump_if_equal): Remove static prototype. Add a
mode argument. Call do_compare_rtx_and_jump.
(emit_case_nodes): Update calls to do_jump_if_equal.
