Subject: [RFC PATCH 0/3] Fix some TCG RISC-V backend bugs
Date: Thu, 20 Oct 2022 18:41:51 +0800 [thread overview]
Message-ID: <20221020104154.4276-1-zhiwei_liu@linux.alibaba.com> (raw)
This patch set fix some bugs in RISC-V backend. It includes:
1. guest regiser using bug in tcg_out_qemu_ld and tcg_out_qemu_st
2. immediate range bug in tcg_out_opc_imm
3. a wrong optimization in tcg_out_addsub2
After this patch set, I can run the 400.perlbench case(spec2006-simple). Besides,
it seems that we can also run RISU on qemu-aarch64(risc-v) now.
I try to run RISU on qemu-aarch64(x86) and qemu-aarch64(risc-v). But this caused
an segment fault. And it's confusing that RISU running on two qemu-aarch64(x86-64)
also caused a segment fault.
LIU Zhiwei (3):
tcg/riscv: Fix base regsiter for qemu_ld/st
tcg/riscv: Fix tcg_out_opc_imm when imm exceeds
tcg/riscv: Remove a wrong optimization for addsub2
