riscv64-unknown-elf-gcc) is used, static linked firmware images are generated instead. Clang/LLVM can still generate PIE images if a bare-metal triple is used (e.g. -target riscv64-unknown-elf). Please note that only a 64-bit version of the toolchain is available in the Bootlin ...
使用riscv-gnu-toolchain工具链和 rv 链接脚本 。 建议使用gcc命令行: riscv64-unknown-elf-gcc example.S -nostdlib -nostartfiles -Tlink.ld -march=rv32imc -mabi=ilp32 -o example.o -e _start -g -no-pie 然后用 obj 工具将0x80000000起始的二进制代码生成能被rv加载的二进制文件: riscv64-unkn...

● -fno-PIE:PIE(Position Independent Executables)表示与位置无关的可执行程序。在GCC中,“-fpic”与“-fPIE”类似,只不过“-fpic”适用于编译动态库,“-fPIE”适用于编译可执行程序。 上述文件会编译和链接两个可执行的ELF文件——benos.elf和mysbi.elf。这些.elf文件包含调试信息,需使用objcopy命令把.elf文件...

orClang/LLVMas they generate PIE firmware images that can run at arbitrary address with appropriate alignment. If a bare-metal GNU toolchain (e.g.riscv64-unknown-elf-gcc) is used, static linked firmware images are generated instead.Clang/LLVMcan still generate PIE images if a bare-metal trip...
基本上,我们更喜欢具有位置无关可执行文件 (PIE) 支持的工具链,例如riscv64-linux-gnu-gcc、riscv64-unknown-freebsd-gcc或 Clang/LLVM,因为它们生成的 PIE 固件映像可以在任意地址运行并进行适当对齐。如果使用裸机 GNU 工具链(例如 riscv64-unknown-elf-gcc),则会生成静态链接固件映像。如果使用裸机三元组(例...
