5288 (fatal_insn): Close the regmove dump file.
5289 (compile_file): Initialize regmove_time; open/close the regmove dump
5290 file as needed. Print regmove time as needed.

5292 RTL after regmove if requested.

5315 * Makefile.in (OBJS): Add alias.o
5316 (alias.o): Add dependencies.
5317 * alias.c: New file.
5318 * sched.c: Remove alias analysis code. It lives in alias.c now.
5319 (sched_analyze_2): Add new arguments to true_dependence.
5320 (schedule_insns): Always call init_alias_analysis.
5321 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
5322 mark return value from such functions as a pointer and keep track of
5323 them for alias analysis. If a return value from a function is a
5324 pointer, mark it as such.
5325 * combine.c (distribute_notes): Handle REG_NOALIAS.
5326 * cse.c (struct write_data): Delete. No longer needed.
5327 (invalidate): Don't call set_nonvarying_address_components anymore.
5328 Use true_dependence to decide if an entry should be removed from
5330 (invalidate_memory): Remove WRITES argument, simplify appropriately.
5332 (note_mem_written): Similarly for WRITE_PTR argument.
5333 (invalidate_from_clobbers): Similarly for W argument.
5334 (invalidate_for_call): Remove memory elements from the hash table.

5337 cse_rtx_addr_varies_p.
5338 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
5339 Don't call note_mem_written anymore. Stack pushes invalidate the stack
5340 pointer if PUSH_ROUNDING is defined. No longer need to call
5341 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
5342 (skipped_writes_memory): Remove variable.
5343 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
5344 (invalidate_skipped_block): Simplify for new alias analysis code.

5361 (copy_loop_body): Likewise.
5362 (final_biv_value): Likewise.
5363 (final_giv_value): Likewise.
5364 (find_splittable_regs): Likewise. Only create one new pseudo
5365 if we have multiple address GIVs that were combined with the same
5366 dst_reg GIV. Note when a new register is created due to unrolling.
5367 * rtl.c (reg_note_name): Add REG_NOALIAS.
5368 * rtl.h (enum reg_note): Similarly.
5369 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
5370 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.

5373 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
5374 (mark_user_reg, mark_reg_pointer): Likewise.
5377 * Integrate reload bugfix from Wilon which enables the PA port
5379 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
5380 OPERAND_ADDRESS when computing how many registers an insn needs.
5381 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
5383 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
5385 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
5386 in reload_reg_use_in_op_addr do not reach the end.
5387 do not reach the end.
5388 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
5389 RELOAD_FOR_OPERAND_ADDRESS.
