1998-10-16Fix consistency problems with reg_equiv_{mem,address};J"orn Rennecke1-3/+12
Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg.

(find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type.

(reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

(compute_use_by_pseudos): New function. (delete_caller_save_insns): Lose argument FIRST. All callers changed. Use the reload_insn_chain instead of walking the rtl directly.

Use the insns_need_reload list instead of something_needs_reloads to find out if reload_as_needed must be called. Clear unused_insn_chains at the end. (calculate_needs_all_insns): Lose FIRST parameter. All callers changed. Delete code to keep track of current basic block. Walk reload_insn_chain instead of the rtl structure. Build the insns_need_reload chain. Remember which insns need reloading/elimination by setting the appropriate fields in struct insn_chain, not by putting modes on the insn. (calculate_needs): Lose THIS_BLOCK arg. Accept arg CHAIN instead of arg INSN. All callers changed. Delete declaration of struct needs. Don't set something_needs_reloads. Record insn needs in the CHAIN argument. (spill_hard_reg): Record the affected pseudos in spilled_pseudos. (reload_as_needed): Lose FIRST arg. All callers changed.

All callers changed. Only mark registers in this_insn_sets. (save_call_clobbered_regs): Rework this function to walk the reload_insn_chain instead of using the list of instructions directly. Delete code to keep track of register lives, compute live regs on the fly from information in the chain. Instead of calling restore_referenced_regs, use mark_referenced_regs, then walk the set it computes and call insert_restore as appropriate. (insert_restore): Lose INSN and BLOCK args. Add CHAIN arg. All callers changed. Restructure the code a bit. Test hard_regs_saved instead of hard_regs_need_restore. (insert_save): Lose INSN and BLOCK args. Add CHAIN and TO_SAVE args. All callers changed. Restructure the code a bit. Use TO_SAVE to determine which regs to save instead of more complicated test. (insert_one_arg): Lose INSN and BLOCK args. Add CHAIN arg. All callers changed. Create a new insn_chain structure for the new insn and place it into the chain. * rtl.texi: Update documentation to reflect that reload no longer puts modes on the insns. From-SVN: r23074

Call delete_caller_save_insns at the end of an iteration if something changed. Delete code to manage caller_save_spill_class. Emit the final note before setting reload_first_uid. Simplify test that determines whether reload_as_needed gets run. (calculate_needs): Delete code to manage caller_save_spill_class. From-SVN: r22876
