@RKSimon I forgot to clarify, the PPC tests crashed on ppc64-P9-vabsd.ll: `lsub_absv_16_ext` and pre-inc-disable.ll: `test_pre_inc_disable_1`, because now the PPC uses custom lowering the `ISD::ABS` node for vector types,
for (MVT VT : MVT::vector_valuetypes()) {
// add/sub are legal for all supported vector VT's.
setOperationAction(ISD::ADD, VT, Legal);
setOperationAction(ISD::SUB, VT, Legal);
setOperationAction(ISD::ABS, VT, Custom);
but the custom lowering for this architecture is not specified.
