[PATCH v2 00/22] Add LoongArch linux-user emulation support
Posted by Song Gao 1 year ago
Hi,

This series only adds linux-user emulation support for LoongArch.
So there is no introduction of system in docs/system directory,
We'll add that in a future series.

Changes for v1:
  * Patch 1, remove unnecessary introduction;
  * Patch 3, follow the ARM/AVR pattern to add new CPU features;
  * Patch 6, remove decode_lsx(); 
  * Patches 7-18, delete opcode definition, modify translation function;
  * Patches 20-22, split V1 patch20 to V2 patch20-22. 

In the next series, we will add privileged instruction emulation, 
board emulation and TCG test. Please review.

Regards
Song Gao
