From 1ce54ad8cd694a1defb9374f18607194ef702ea7 Mon Sep 17 00:00:00 2001 From: Takayuki 'January June' Suwa Date: Sun, 18 Jun 2023 16:07:12 +0900 Subject: [PATCH] xtensa: Remove TARGET_MEMORY_MOVE_COST hook It used to always return a constant 4, which is same as the default behavior, but doesn't take into account the effects of secondary reloads. Therefore, the implementation of this target hook is removed. gcc/ChangeLog: * config/xtensa/xtensa.cc (TARGET_MEMORY_MOVE_COST, xtensa_memory_move_cost): Remove. --- gcc/config/xtensa/xtensa.cc | 13 ------------- 1 file changed, 13 deletions(-) diff --git a/gcc/config/xtensa/xtensa.cc b/gcc/config/xtensa/xtensa.cc index 3b5d25b660a..721c99b56a3 100644 --- a/gcc/config/xtensa/xtensa.cc +++ b/gcc/config/xtensa/xtensa.cc @@ -131,7 +131,6 @@ static bool xtensa_rtx_costs (rtx, machine_mode, int, int, int *, bool); static int xtensa_insn_cost (rtx_insn *, bool); static int xtensa_register_move_cost (machine_mode, reg_class_t, reg_class_t); -static int xtensa_memory_move_cost (machine_mode, reg_class_t, bool); static tree xtensa_build_builtin_va_list (void); static bool xtensa_return_in_memory (const_tree, const_tree); static tree xtensa_gimplify_va_arg_expr (tree, tree, gimple_seq *, @@ -213,8 +212,6 @@ static rtx xtensa_delegitimize_address (rtx); #undef TARGET_REGISTER_MOVE_COST #define TARGET_REGISTER_MOVE_COST xtensa_register_move_cost -#undef TARGET_MEMORY_MOVE_COST -#define TARGET_MEMORY_MOVE_COST xtensa_memory_move_cost #undef TARGET_RTX_COSTS #define TARGET_RTX_COSTS xtensa_rtx_costs #undef TARGET_INSN_COST @@ -4356,16 +4353,6 @@ xtensa_register_move_cost (machine_mode mode ATTRIBUTE_UNUSED, return 10; } -/* Worker function for TARGET_MEMORY_MOVE_COST. */ - -static int -xtensa_memory_move_cost (machine_mode mode ATTRIBUTE_UNUSED, - reg_class_t rclass ATTRIBUTE_UNUSED, - bool in ATTRIBUTE_UNUSED) -{ - return 4; -} - /* Compute a (partial) cost for rtx X.
