2018-03-01 Tom de Vries <tom@codesourcery.com>
PR rtl-optimization/83327
* lra-int.h (hard_regs_spilled_into): Declare.
* lra.c (hard_regs_spilled_into): Define.
(init_reg_info): Init hard_regs_spilled_into.
* lra-spills.c (assign_spill_hard_regs): Update hard_regs_spilled_into.
* lra-lives.c (make_hard_regno_born, make_hard_regno_dead)
(process_bb_lives): Handle hard_regs_spilled_into.
(lra_create_live_ranges_1): Before doing liveness propagation, clear
regs in all_hard_regs_bitmap if set in hard_regs_spilled_into.
