--- Comment #7 from Jacob Lifshay <programmerjake at gmail.com> ---
I added all the ops to the spec, I'll leave opcode allocation to #899:

https://git.libre-soc.org/?p=libreriscv.git;a=commitdiff;h=3e363081ee0142d6948d5b6c66523d833d0a7711

I found x86-style min/max ops in VSX (xsmincdp), so I'll take that as
sufficient justification to add scalar ops. I named them fminc/fmaxc to mirror
the VSX ops and to avoid sticking x86 in the opcode mnemonics.
