[PATCH 00/20] Add LoongArch linux-user emulation support
Posted by Song Gao 1 year, 1 month ago
Hi,

This series adds linux-user emulation support for LoongArch.

Patch 1 add an introduction to LoongArch.
Patches 2-5 adds LoongArch basic definition.
Patches 6-18 implements user mode instruction emulation.
Patche 19 add support for disassembling via option '-d in_asm'
Patch 20 add files to linux-user/loongarch64 and support compilling
linux-user binary.

About LoongArch, please see:
   https://github.com/loongson/LoongArch-Documentation

Please review!

thanks
