[PATCH v2 15/19] target/ppc: Move dcmp{u, o}[q], dts{tex, tsf, tsfi}[q] to decodetree |
|
Date: |
Tue, 31 Aug 2021 13:40:03 -0300 |
Move the following instructions to decodetree:
dcmpu: DFP Compare Unordered
dcmpuq: DFP Compare Unordered Quad
dcmpo: DFP Compare Ordered
dcmpoq: DFP Compare Ordered Quad
dtstex: DFP Test Exponent
dtstexq: DFP Test Exponent Quad
dtstsf: DFP Test Significance
dtstsfq: DFP Test Significance Quad
dtstsfi: DFP Test Significance Immediate
dtstsfiq: DFP Test Significance Immediate Quad
