easy_linker

介绍

一款64位RISC-V指令集的静态链接器，目前只支持解析ELF文件格式，后续会加入PE的支持。

交叉编译工具

• sudo apt upgrate
  
• sudo apt install qemu-user
  
• sudo apt search risc
  
• sudo apt install gcc-12-riscv64-linux-gnu
  
• sudo ln -sf /usr/bin/riscv64-linux-gnu-gcc-12 /usr/bin/riscv64-linux-gnu-gcc
  

linker大致流程

• Command line options
• Symbol resolution (including archive processing)
• Process input sections
• Section based garbage collection / identical code folding
• Create synthetic (linker generated) sections
• Scan relocations
• Create output sections
• Assign input sections to output sections
• Write file header
• Write sections
