Re: proposal for stateen CSRs
toggle quoted message Show quoted text
Code that does environment swapping will need to use custom instructions to save custom state, so might as well use custom CSRs for the individual enable bits instead of taking up space in the standard *stateen.
The use case for the single bit is only for M-mode software that wants to enable/disable all custom state. No need to take up more than a single bit for that.
