+ * reload1.c (reg_reloaded_call_part_clobbered): Clarify comment.
+ (forget_old_reloads_1, forget_marked_reloads): Don't clear

+ (reload_regs_reach_end_p): New function.
+ (reload_reg_rtx_for_input): New variable.
+ (reload_reg_rtx_for_output): Likewise.
+ (emit_input_reload_insns): Use reloadreg rather than rl->reg_rtx
+ when reassigning a pseudo register. Load reloadreg from
+ reload_reg_rtx_for_input, moving the mode and register
+ calculation to...
+ (do_input_reload): ...here. Use the mode-adjusted reg_rtx
+ instead of the original when deciding whether an input reload
+ would be a no-op or whether an output reload can be deleted.
+ (emit_output_reload_insns): Use the mode-adjusted reg_rtx
+ when setting up new_spill_reg_store. Load it from
+ reload_reg_rtx_for_output, moving the mode and register
+ calculation to...
+ (do_output_reload): ...here. Use the mode-adjusted reg_rtx
+ instead of the original when deciding whether an output reload
+ would be a no-op. Do the same when modifying insn notes.
+ Use rtx_equal_p instead of == to compare the registers.
+ (inherit_piecemeal_p): Take a mode and two register numbers
+ as argument.
+ (emit_reload_insns): Clear new_spill_reg_store for every hard
+ register in the reload register. Remove spill registers
+ from reg_reloaded_valid before considering whether to record
+ inheritance information for them. Use reload_reg_rtx_for_output
+ instead of reg_rtx when recording output reloads. Use
+ reload_reg_rtx_for_input instead of reg_rtx when recording
+ input reloads. Set or clear reg_reloaded_call_part_clobbered
+ at the same time as setting reg_reloaded_valid.
+ (delete_output_reload): Add a new_reload_reg parameter and use it
