[Qemu-devel] [PATCH for-2.12 0/2] RISC-V: Mark FP status dirty

[Richard Henderson]

Since it was my patch that broke FP state tracking in the
first place, I feel obligated to fix it again.

Mark mstatus[fs] as dirty whenever we write to the file.
This can be optimized by only doing so once within a TB
which initially began with a clean file.

I have not yet put together an environment that can test
this, so I'll need someone else to give it a go.
