[PATCH] D136076: [LoongArch] Report error in AsmParser when rd == rk or rd == rj for AM* instructions

[WÁNG Xuěruì via Phabricator via llvm-commits]

xen0n added a comment.

The changes look good but unfortunately the manual (!) is poorly translated in this case. Quoting verbatim, while still comprehensible, is an eyesore that is better fixed.

Here's my take:

  Do this check because the ISA manual says (edited from the original translation):
  
  > If the AM* instruction has its rd == rj, an Instruction Non-defined Exception will be triggered when the instruction is executed.
  >
  > If the AM* instruction has its rd == rk, the execution result is unpredictable. It is software's responsibility to avoid this situation.

What do you think?
