通常所说的GCC是GUN Compiler Collection的简称,是Linux系统上常用的编译工具。GCC实质上不是一个单独的程序,而是多个程序的集合,因此通常称为GCC工具链。工具链软件包括GCC、C运行库、Binutils、GDB等。 GCC GCC(GNU C Compiler)是编译工具。本文所要介绍的将C/C++语言编写的程序转换成为处理器能够执行的二进制代码...

✗ riscv64-unknown-elf-gcc -march=rv32imac -mabi=ilp32 -S 这样体验一把就行。Compiler 需要走: Lexer: 语法分析,把目标转成 token. 实际上可以借用 Lex 工具,而 Flex 是 Lex 的一个实现。 Parser: 将内容变为 AST Semantic Analysis and Optimization: 检查 AST, 然后做一些优化 Code generation: ...
To build the Newlib cross-compiler, pick an install path (that is writeable). If you choose, say,/opt/riscv, then add/opt/riscv/binto yourPATH. Then, simply run the following command: ./configure --prefix=/opt/riscv make You should now be able to use riscv64-unknown-elf-gcc and...

1、CROSS_COMPILE:交叉编译器的前缀,表示将代码编译编译成目标CPU指令的工具,如果不指定,make 会默认使用系统自带的 gcc 来编译,这里指定我们之前编译出来的 riscv64-unknown-linux-gnu- 为前缀。 2、ARCH:即 architecture ,用于选择编译哪种 CPU 架构,也就是编译 arch/ 目录下的哪个子目录,这里指定 ARCH=riscv...
