Add implicit parameter to find_all_hard_reg_sets
2014-04-25 Radovan Obradovic <robradovic@mips.com>
Tom de Vries <tom@codesourcery.com>
* rtlanal.c (find_all_hard_reg_sets): Add bool implicit parameter and
handle.
* rtl.h (find_all_hard_reg_sets): Add bool parameter.
* haifa-sched.c (recompute_todo_spec, check_clobbered_conditions): Add
new argument to find_all_hard_reg_sets call.
