How so, because it most certainly has FP support? I am only aware that there were 2 broken FP instructions, c.fsw
and c.fswsp
, before you made this PR, can you open an issue on my repo with what you're seeing.

@Yangff this is fixed in the latest version of the RISCV plugin and the instruction starting at 2301505a correctly disassembled as c.fswsp
@stschake beat me to it, sorry should have been more specific, I had just fixed that when I posted in the other thread, and you would have needed to update. That will decode now into fsw
instructions
