The TableGen immAllOnesV and immAllZerosV helpers implicitly wrapped the ISD::isBuildVectorAll(Ones|Zeros) helper functions. This was inhibiting their use for targets such as RISC-V which use ISD::SPLAT_VECTOR. In particular, RISC-V had to define its own 'vnot' fragment. In order to extend the scope of these nodes to include support for ISD::SPLAT_VECTOR, two new ISD predicate functions have been introduced: ISD::isConstantSplatVectorAll(Ones|Zeros). These effectively supersede the older "isBuildVector" predicates, which are now simple wrappers for the new functions. They pass a defaulted boolean toggle which preserves the old behaviour. It is hoped that in time all call-sites can be ported to the "isConstantSplatVector" functions. While the use of ISD::isBuildVectorAll(Ones|Zeros) has not changed, the behaviour of the TableGen immAll(Ones|Zeros)V **has**. To test the new functionality, the custom RISC-V TableGen fragment has been removed and replaced with the built-in 'vnot'. To test their use as pattern-roots, two splat patterns have been updated accordingly. Reviewed By: craig.topper Differential Revision: https://reviews.llvm.org/D94223 |
