1485 * Integrate alias analysis changes from jfc@mit.edu
1486 * Makefile.in (OBJS): Add alias.o
1487 (alias.o): Add dependencies.
1488 * alias.c: New file.
1489 * sched.c: Remove alias analysis code. It lives in alias.c now.
1490 (sched_analyze_2): Add new arguments to true_dependence.
1491 (schedule_insns): Always call init_alias_analysis.
1492 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
1493 mark return value from such functions as a pointer and keep track of
1494 them for alias analysis. If a return value from a function is a
1495 pointer, mark it as such.
1496 * combine.c (distribute_notes): Handle REG_NOALIAS.
1497 * cse.c (struct write_data): Delete. No longer needed.
1498 (invalidate): Don't call set_nonvarying_address_components anymore.
1499 Use true_dependence to decide if an entry should be removed from
1501 (invalidate_memory): Remove WRITES argument, simplify appropriately.
1503 (note_mem_written): Similarly for WRITE_PTR argument.
1504 (invalidate_from_clobbers): Similarly for W argument.
1505 (invalidate_for_call): Remove memory elements from the hash table.
1506 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
1507 (cse_rtx_varies_p): New function. Derived from old
1508 cse_rtx_addr_varies_p.
1509 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
1510 Don't call note_mem_written anymore. Stack pushes invalidate the stack
1511 pointer if PUSH_ROUNDING is defined. No longer need to call
1512 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
1513 (skipped_writes_memory): Remove variable.
1514 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
1515 (invalidate_skipped_block): Simplify for new alias analysis code.
1516 (cse_set_around_loop): Likewise.
1517 (cse_main): Call init_alias_analysis.
1518 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
1519 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
1520 (f_options): Add new alias checking arguments.
1521 (main): Set flag_alias_check when optimizing.
1522 * local_alloc (validate_equiv_mem_from_store): Add new arguments
1524 (memref_referenced_p): Likewise.
1525 * loop.c (NUM_STORES): Increase to 30.
1526 (prescan_loop): Only non-constant calls set unknown_address_altered.
1527 (invariant_p): Add new arguments to true_dependence.
1528 (record_giv): Initialize unrolled and shared fields.
1529 (emit_iv_add_mult): Call record_base_value as needed.
1530 * loop.h (struct induction): Add unrolled and shared fields.
1531 * unroll.c (unroll_loop): Call record_base_value as needed.
1532 (copy_loop_body): Likewise.
1533 (final_biv_value): Likewise.
1534 (final_giv_value): Likewise.
1535 (find_splittable_regs): Likewise. Only create one new pseudo
1536 if we have multiple address GIVs that were combined with the same
1537 dst_reg GIV. Note when a new register is created due to unrolling.
1538 * rtl.c (reg_note_name): Add REG_NOALIAS.
1539 * rtl.h (enum reg_note): Similarly.
1540 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
1541 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
1542 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
1543 (true_dependence, read_dependence, anti_dependence): Likewise.
1544 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
1545 (mark_user_reg, mark_reg_pointer): Likewise.
1548 * Integrate reload bugfix from Wilon which enables the PA port
1550 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
1551 OPERAND_ADDRESS when computing how many registers an insn needs.
1552 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
1554 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
1556 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
1557 in reload_reg_use_in_op_addr do not reach the end.
1558 do not reach the end.
1559 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
1560 RELOAD_FOR_OPERAND_ADDRESS.
