-fuse-caller-save - Collect register usage information
2014-05-28 Radovan Obradovic <robradovic@mips.com>
Tom de Vries <tom@codesourcery.com>
* cgraph.h (struct cgraph_rtl_info): Add function_used_regs
and function_used_regs_valid fields.
* final.c: Move include of hard-reg-set.h to before rtl.h to declare
find_all_hard_reg_sets.
(collect_fn_hard_reg_usage, get_call_fndecl, get_call_cgraph_rtl_info)
(get_call_reg_set_usage): New function.
(rest_of_handle_final): Use collect_fn_hard_reg_usage.
* regs.h (get_call_reg_set_usage): Declare.
