[RISCV] Add CSR RegisterClass and save/restore fcsr in interrupt

[wangpc]

Summary

We add a new RegisterClass to represent CSRs and modify
storeRegToStackSlot/loadRegFromStackSlot so that we can
save/restore these CSRs.

This is an alternative of D158396

[wangpc]

Fix wrong restore dst reg.

[wangpc]

Fix paste error.

[wangpc]

CSR restore should be ahead.

If we put FCSR at first in CSR_XLEN_F32_Interrupt/CSR_XLEN_F64_Interrupt, is it still need to depend on save or restore to determinate the order of CSR inserted.

Typo. IsRestore.

[wangpc]

Fix typo.

Yes. We should save FCSR after saving t0 and restore it before restoring t0 since we are using t0 as a temporary register.

Gentle ping. :-)

This seems tricky to me to hardcode a GPR in here. This makes the code only work in certain scenarios. Do other targets do anything like this?

We just need a GPR to store the value of CSRs.

This makes the code only work in certain scenarios.

I don't get it. This code is only for saving CSRs.

No, I haven't find any target doing this.

I don't get it. This code is only for saving CSRs.

It only works in the prolog and epilogue where that GPR is available. loadRegFromStackSlot and storeRegToStackSlot are normally also used for spills and reloads, but that wouldn’t work if we ever needed that for CSRs.

This overlaps with FRM and FFLAGS. Probably at least deserves a comment about why they aren’t subregs.

[asb]

Left a trivial comment. Not sure on this vs D158396 - the logic of the other patch does seem a bit easier to follow as you suggested in your comment there.

We should probably mention fcsr in this comment (and the one for f64 below).

I think it's more consistent than D158396 if consider CSRs as callee-saved register in one consistent place and infra.

Probably it can refer to SPILL_CR like Pseudo in PPC target. Just use Pseudo here and expand later in eliminateFrameIndex where introduce internal virtual GPR, then it would be scavenged later

Thanks, I'll have a try!
