有关-march和-mabi选项的含义。 2: 以“riscv64-unknown-elf-”为前缀的版本 同上 以“riscv64-unknown-elf-”为前缀的版本表示该版本为非Linux(Non-linux)版本的工具链,此Non-Linux不是指当前版本工具链一定不能运行在Linux操作系统的电脑上,此Non-Linux是指该GCC工具链会使用newlib作为C运行库。同上理,...
riscv64-unknown-elf-gcc 的主要用途包括: 编译RISC-V 架构的裸机程序:由于没有特定于操作系统的假设,该编译器非常适合用于编译直接运行在硬件上的裸机程序。 开发RISC-V 架构的操作系统:在操作系统的早期引导阶段,通常需要编译裸机程序,这时 riscv64-unknown-elf-gcc 就非常有用。 嵌入式系统开发:对于需要直接控...
