* gcc.c (SWITCH_TAKES_ARG): Add 'V', 'B' and 'b'. (process_command): Increment n_switches for them. Don't discard their args. Validate them. (main): Escape " marks when creating COLLECT_GCC_OPTIONS. From Rohan Lenard. (process_command): Set include_prefixes from COMPILER_PATH. (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. * Makefile.in (USE_COLLECT2): Always use collect2. (collect2): Depend on and link in hash.o and tlink.o. (tlink.o, hash.o): Add dependencies. tlink patches from Jason. From-SVN: r14769 -

* 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. (reg_last_uses_size): Declare. (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. jfc's alias analysis code. From-SVN: r14768 -

to bootstrap again. * reload1.c (reload): Sum needs for both OPADDR_ADDR and 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. Start a new ChangeLog for gcc3. From-SVN: r14767 -
