Hi.
This patch converts loops of SET_HARD_REG_BIT in to add_to_hard_reg_set
functions call.
The patch has been bootstrapped on and regression tested on
x86_64-unknown-linux-gnu for c.
OK to install?
* expr.c (expand_expr_real_1): Use add_to_hard_reg_set function
instead of loop.
* sel-sched.c (mark_unavailable_hard_regs): Likewise.
* function.c (record_hard_reg_sets): Likewise.
* ira.c (compute_regs_asm_clobbered): Likewise.
* sched-deps.c (sched_analyze_1): Likewise.
* reload1.c (mark_reload_reg_in_use, choose_reload_regs): Likewise.
