从 riscv-gnu-toolchain 生成的 s 文件没有 运行 RISCV 模拟器
s-files generated from riscv-gnu-toolchain does not run RISCV emulator
我必须将一组 C++ 文件编译成 RISC-V 代码 (RV32IM)。我正在使用 riscv-gnu-toolchain 并使用以下 CMakeLists.txt 文件
进行编译
cmake_minimum_required(VERSION 3.10.2)
project(project-title)
set(CMAKE_CXX_FLAGS "-march=rv32im -mabi=ilp32 --save-temps")
set(CMAKE_CXX_COMPILER riscv32-unknown-elf-g++)
如果我输入一个测试 C++ 文件，如下所示
#include <iostream>
using namespace std;
int main() {
cout << "Hello, world!" << endl;
}
然后它会生成以下 .s 文件
.file "test.cpp"

如果我在 RISCV 模拟器中尝试 运行 这个（例如 Jupiter or BRISC-V），那么我似乎没有被识别为有效的 RISC-V 代码。
如果我尝试 运行 和 riscv32-unknown-elf-run，它会 运行 成功。

Jupiter: (error) simulation halted due to assembly errors
你唯一做错的是你使用了两个不同的汇编程序。 g++ 工具链使用 gas，它最多使用 AT&T 语法，而我不熟悉的 Jupiter 使用另一种语法。
如果它们之间有任何兼容性桥梁，那么这是您唯一可以遵循的方法。如果没有兼容性，则必须选择一方。
如果您选择 g++ 又名 Gnu Compiler Collection，那么可以使用一个模拟器，Qemu。
如果您选择 Jupiter，我认为您必须使用 Jupiter 的语法编写汇编。
我必须将一组 C++ 文件编译成 RISC-V 代码 (RV32IM)。我正在使用 riscv-gnu-toolchain 并使用以下 CMakeLists.txt 文件
进行编译cmake_minimum_required(VERSION 3.10.2)

如果我输入一个测试 C++ 文件，如下所示

然后它会生成以下 .s 文件

你唯一做错的是你使用了两个不同的汇编程序。 g++ 工具链使用 gas，它最多使用 AT&T 语法，而我不熟悉的 Jupiter 使用另一种语法。
如果它们之间有任何兼容性桥梁，那么这是您唯一可以遵循的方法。如果没有兼容性，则必须选择一方。
如果您选择 g++ 又名 Gnu Compiler Collection，那么可以使用一个模拟器，Qemu。
如果您选择 Jupiter，我认为您必须使用 Jupiter 的语法编写汇编。
