2017-01-17 Thread Wilco Dijkstra
After Bernd's DImode patch [1] almost all DImode operations are expanded early (except for -mfpu=neon). This means the Thumb-2 iordi_notdi_di patterns are no longer used - the split ORR and NOT instructions are merged into ORN by Combine. With -mfpu=neon the iordi_notdi_di patterns are used on Thu
