	Store inc into fp->inc so that record_control_macro doesn't
	need to do a table lookup.

	(TARGET_SWITCHES): Add -mlinker-opt.

	* pa.md (all peepholes): Disable if TARGET_SOFT_FLOAT.

	* pa.c (pa_reorg): If TARGET_GAS, then emit insns to mark
	the beginning and end of the branch table.
	* pa.md (begin_brtab): New insn.  Just a marker so GCC knows
	where to put the .begin_brtab pseudo-op.
	(end_brtab): Similarly.

	* pa.h (EXTRA_SECTIONS): Add in_ctors and in_dtors if
	CTORS_SECTION_FUNCTION is defined.  Else define dummy
	versions of CTORS_SECTION_FUNCTION and DTORS_SECTION_FUNCTION.
	(EXTRA_SECTION_FUNCTIONS): Add CTORS_SECTION_FUNCTION and
	DTORS_SECTION_FUNCTION.

	* pa.md: Add peepholes to improve spill code generated
	by reload when we run out of FP registers.

	* xm-pa.h: Remove spurious double-quote.

	* pa.md (call expanders): For indirect calls, load %r22 with the
	function's address.
	(indirect call patterns): No need to copy the call address into
	%r22 anymore.

	* pa.c (output_cbranch): Fix buglet in length handling of
	backwards branches with unfilled delay slots.
	(output_bb, output_bvb, output_dbra, output_movb): Likewise.

	* pa.md: Fix off-by-one error in length computations for all
	conditional branch patterns.

	* pa.h (output_bvb): Declare.
	* pa.c (output_bvb): New function to output branch on variable
	bit insns.
	* pa.md (branch-on-variable-bit): New patterns.

	* pa.h (TARGET_MILLICODE_LONG_CALLS): Delete swtich and all
	references.
	(output_millicode_call): Declare new function
	* pa.md (millicode calls): Update length computation to handle
	variable length millicode calls.
	(call pattners): Likewise.
	(indirect call patterns): Update length compuations and output
	templates to handle variable length millicode calls.
	(plabel_dereference): Likewise.
	* pa.c (override_options): Give warnings when incompatable
	options are used.
	(output_mul_insn): Call output_millicode_call instead of
	output_call, eliminate last argument to output_millicode_call.
	(output_div_insn): Likewise.
	(output_mod_insn): Likewise.
	(output_call): Rewrite long call code to handle variable length
	millicode calls.  Eliminate support for calling mul, div and mod
	millicode routines.
	(output_millicode_call): New function for calling mul, div and mod
	millicode routines.

	* pa.md (abssi2): New pattern.

	* pa.c (secondary_reload_class): Loads from reg+d addresses into
	FP registers don't need secondary reloads.
	* pa.h: Delete soem #if 0 code.  Update some comments.
	(EXTRA_CONSTRAINT, case 'Q'): Only accept valid memory addresses.

	* pa.h (RTX_COSTS): Tege's rewrite.

	* pa.c (hppa_legitimize_address): Generate unscaled indexed
	addressing for (plus (symbol_ref) (reg)).
	(emit_move_sequence): Set REGNO_POINTER_FLAG appropriately
	to encourage unscaled indexing modes.
	(basereg_operand): New function for unscaled index address support.
	* pa.md (unscaled indexing patterns): New patterns for unscaled
	index address support.

	* pa.h (MOVE_RATIO): Define.
	* pa.md (movstrsi expander): Refine tests for when to use the
	library routine instead of an inlined loop copy.  Provide an
	additional scratch register for use in the inlined loop copy.
	(movstrsi_internal): Name the pattern for ease of use.  Add
	additional scratch register.
	* pa.c (output_block_move): Greatly simplify.  Use 2X unrolled
	copy loops to improve performance.
	(compute_movstrsi_length): Corresponding changes.

	* pa.c (print_operand): Handle 'y' case for reversed FP
	comparisons.  Delete some #if 0 code.  Fix various comment typos.
	* pa.md (fcmp patterns): Try and reverse the comparison to avoid
	useless add,tr insns.
