Subject: Reorganize post-ra pipeline for targets without register allocation.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=433e4164339f18d0b8798968444a56b681b5232c;p=gcc.git

Reorganize post-ra pipeline for targets without register allocation.

	* passes.def (pass_compute_alignments, pass_duplicate_computed_gotos,
	pass_variable_tracking, pass_free_cfg, pass_machine_reorg,
	pass_cleanup_barriers, pass_delay_slots,
	pass_split_for_shorten_branches, pass_convert_to_eh_region_ranges,
	pass_shorten_branches, pass_est_nothrow_function_flags,
	pass_dwarf2_frame, pass_final): Move outside of pass_postreload and
	into pass_late_compilation.
	(pass_late_compilation): Add.
	* passes.c (pass_data_late_compilation, pass_late_compilation,
	make_pass_late_compilation): New.
	* timevar.def (TV_LATE_COMPILATION): New.
