Commit Message

David Gibson Nov. 9, 2021, 5:51 a.m. UTC 
From: Luis Pires <luis.pires@eldorado.org.br>

Move the following instructions to decodetree:
ddedpd:  DFP Decode DPD To BCD
ddedpdq: DFP Decode DPD To BCD Quad
denbcd:  DFP Encode BCD To DPD
denbcdq: DFP Encode BCD To DPD Quad
dscli:   DFP Shift Significand Left Immediate
dscliq:  DFP Shift Significand Left Immediate Quad
dscri:   DFP Shift Significand Right Immediate
dscriq:  DFP Shift Significand Right Immediate Quad

Also deleted dfp-ops.c.inc, now that all PPC DFP instructions were
moved to decodetree.
