	gcc            : ChangeLog final.c flags.h invoke.texi tm.texi 
	                 toplev.c varasm.c 
	gcc/config/mips: mips.c mips.md 
	gcc/config/sparc: sparc.c sparc.h 

Log message:
	* flags.h: New variables align_loops, align_loops_log,
	align_jumps, align_jumps_log, align_labels, align_labels_log,
	align_functions, align_functions_log.
	* toplev.c: Define them.
	(f_options): Handle -falign-* when they have no argument.
	(main): Add logic to set variables for -falign-functions,
	-falign-jumps, -falign-labels, -falign-loops.
	Make it -fsched-verbose=<n> and -finline-limit=<n>.
	(display_help): Change help to match options.
	* final.c (LABEL_ALIGN): Default to align_labels_log.
	(LABEL_ALIGN_MAX_SKIP): Default to align_labels-1.
	(LOOP_ALIGN): Default to align_loops_log.
	(LOOP_ALIGN_MAX_SKIP): Default to align_loops-1.
	(LABEL_ALIGN_AFTER_BARRIER): Default to align_jumps_log.
	(LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Default to align_jumps-1.
	* varasm.c (assemble_start_function): Handle align_functions.
	
	* config/sparc/sparc.h: Don't declare sparc_align_*.
	Don't provide LABEL_ALIGN_AFTER_BARRIER or LOOP_ALIGN.
	(DEFAULT_SPARC_ALIGN_FUNCS): Delete; take functionality into
	sparc.c.
	(FUNCTION_BOUNDARY): Fix incorrect use---it's not just a request,
	it's a promise.
	* config/sparc/sparc.c: Delete sparc_align_loops,
	sparc_align_jumps, sparc_align_funcs and the corresponding string
	variables.
	(sparc_override_options): Default align_functions on ultrasparc.
	Delete -malign-* handling.
	
	* config/mips/mips.c (override_options):  On 64-bit targets,
	try to align code to 64-bit boundaries.
	(print_operand): New substitution, %~,
	which aligns labels to align_labels_log.
	* config/mips/mips.md (div_trap_normal): Use %~.
	(div_trap_mips16): Likewise.
	(abssi): Likewise.
	(absdi2): Likewise.
	(ffssi2): Likewise.
	(ffsdi2): Likewise.
	(ashldi3_internal): Likewise.
	(ashrdi3_internal): Likewise.
	(lshrdi3_internal): Likewise.
	(casesi_internal): Likewise.
	
	Plus corresponding documentation changes.
