> PR c++/59813
> PR tree-optimization/89060
> * tree-ssa-live.h (live_vars_map): New typedef.
> (compute_live_vars, live_vars_at_stmt, destroy_live_vars): Declare.
> * tree-ssa-live.c: Include gimple-walk.h and cfganal.h.
> (struct compute_live_vars_data): New type.
> (compute_live_vars_visit, compute_live_vars_1, compute_live_vars,
> live_vars_at_stmt, destroy_live_vars): New functions.
> * tree-tailcall.c: Include tree-ssa-live.h.
> (live_vars, live_vars_vec): New global variables.
> (find_tail_calls): Perform variable life analysis before punting.
> (tree_optimize_tail_calls_1): Clean up live_vars and live_vars_vec.
> * tree-inline.h (struct copy_body_data): Add eh_landing_pad_dest
> member.
> * tree-inline.c (add_clobbers_to_eh_landing_pad): Remove BB argument.
> Perform variable life analysis to select variables that really need
> clobbers added.
> (copy_edges_for_bb): Don't call add_clobbers_to_eh_landing_pad here,
> instead set id->eh_landing_pad_dest and assert it is the same.
> (copy_cfg_body): Call it here if id->eh_landing_pad_dest is non-NULL.
