+	From Rohan Lenard.

+	(main): Set COLLECT_GCC_OPTIONS sooner.
+	* confiugre.in: Link ../ld/ld.new to collect-ld rather than real-ld.
+	* tlink.c, hash.c, hash.h: New files.

+
+	* Integrate alias analysis changes from jfc@mit.edu
+	* Makefile.in (OBJS): Add alias.o
+	(alias.o): Add dependencies.
+	* alias.c: New file.
+	* sched.c: Remove alias analysis code.  It lives in alias.c now.
+	(sched_analyze_2): Add new arguments to true_dependence.
+	(schedule_insns): Always call init_alias_analysis.
+	* calls.c (expand_call): Note calls to malloc, calloc, and realloc;
+	mark return value from such functions as a pointer and keep track of
+	them for alias analysis.  If a return value from a function is a
+	pointer, mark it as such.
+	* combine.c (distribute_notes): Handle REG_NOALIAS.
+	* cse.c (struct write_data): Delete.  No longer needed.
+	(invalidate): Don't call set_nonvarying_address_components anymore.
+	Use true_dependence to decide if an entry should be removed from
+	the hash table.
+	(invalidate_memory): Remove WRITES argument, simplify appropriately.
+	Fix all callers.
+	(note_mem_written): Similarly for WRITE_PTR argument.
+	(invalidate_from_clobbers): Similarly for W argument.
+	(invalidate_for_call): Remove memory elements from the hash table.
+	(refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
+	(cse_rtx_varies_p): New function.  Derived from old
+	cse_rtx_addr_varies_p.
+	(cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
+	Don't call note_mem_written anymore.  Stack pushes invalidate the stack
+	pointer if PUSH_ROUNDING is defined.  No longer need to call
+	cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
+	(skipped_writes_memory): Remove variable.
+	(invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
+	(invalidate_skipped_block): Simplify for new alias analysis code.
+	(cse_set_around_loop): Likewise.
+	(cse_main): Call init_alias_analysis.
+	* flags.h (flag_alias_check, flag_argument_noalias): Declare.
+	* toplev.c (flag_alias_check, flag_argument_noalias): Define.
+	(f_options): Add new alias checking arguments.
+	(main): Set flag_alias_check when optimizing.
+	* local_alloc (validate_equiv_mem_from_store): Add new arguments
+	to true_dependence.
+	(memref_referenced_p): Likewise.
+	* loop.c (NUM_STORES): Increase to 30.
+	(prescan_loop): Only non-constant calls set unknown_address_altered.
+	(invariant_p): Add new arguments to true_dependence.
+	(record_giv): Initialize unrolled and shared fields.
+	(emit_iv_add_mult): Call record_base_value as needed.
+	* loop.h (struct induction): Add unrolled and shared fields.
+	* unroll.c  (unroll_loop): Call record_base_value as needed.
+	(copy_loop_body): Likewise.
+	(final_biv_value): Likewise.
+	(final_giv_value): Likewise.
+	(find_splittable_regs): Likewise.  Only create one new pseudo
+	if we have multiple address GIVs that were combined with the same
+	dst_reg GIV.  Note when a new register is created due to unrolling.
+	* rtl.c (reg_note_name): Add REG_NOALIAS.
+	* rtl.h (enum reg_note): Similarly.
+	(rtx_varies_p, may_trap_p, side_effects_p): Declare.
+	(volatile_refs_p, volatile_insn_p, remove_note): Likewise.
+	(note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
+	(true_dependence, read_dependence, anti_dependence): Likewise.
+	(output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
+	(mark_user_reg, mark_reg_pointer): Likewise.
+
+
+	* Integrate reload bugfix from Wilon which enables the PA port
+	to bootstrap again.
+	* reload1.c (reload): Sum needs for both OPADDR_ADDR and
+	OPERAND_ADDRESS when computing how many registers an insn needs.
+	(reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
+	conflict.
+	(reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
+	OPADDR_ADDR reload.
+	(reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
+	in reload_reg_use_in_op_addr do not reach the end.
+	do not reach the end.
+	(reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
+	RELOAD_FOR_OPERAND_ADDRESS.
