(sched_analyze_2): Add new arguments to true_dependence.
(sched_analyze_insn): Use reg_last_uses_size instead of max_reg.
(schedule_block): Initialize reg_last_uses_size.
(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.
