From 4329d111f48cba9ea560fc0a36f4cb5a290decb2 Mon Sep 17 00:00:00 2001 From: Ju-Zhe Zhong Date: Tue, 25 Oct 2022 21:53:23 +0800 Subject: [PATCH] RISC-V: Fix epilogue generation for barrier. I noticed that I have made a mistake in previous patch: https://patchwork.sourceware.org/project/gcc/patch/20220817071950.271762-1-juzhe.zhong@rivai.ai/ The previous statement before this patch: bool need_barrier_p = (get_frame_size () + cfun->machine->frame.arg_pointer_offset) != 0; However, I changed it in the previous patch: bool need_barrier_p = known_ne (get_frame_size (), cfun->machine->frame.arg_pointer_offset); This is incorrect. Now, I correct this statement in this patch. gcc/ChangeLog: * config/riscv/riscv.cc (riscv_expand_epilogue): Fix statement. --- gcc/config/riscv/riscv.cc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/gcc/config/riscv/riscv.cc b/gcc/config/riscv/riscv.cc index fac8def31d85..3d02954ffce9 100644 --- a/gcc/config/riscv/riscv.cc +++ b/gcc/config/riscv/riscv.cc @@ -5025,8 +5025,8 @@ riscv_expand_epilogue (int style) rtx insn; /* We need to add memory barrier to prevent read from deallocated stack. */ - bool need_barrier_p - = known_ne (get_frame_size (), cfun->machine->frame.arg_pointer_offset); + bool need_barrier_p = known_ne (get_frame_size () + + cfun->machine->frame.arg_pointer_offset, 0); if (cfun->machine->naked_p) { -- 2.47.2
