================
Comment at: llvm/lib/Target/AArch64/AArch64TargetTransformInfo.h:285
+ // Return true if we can generate a `ld1r` splat load instruction.
+ if (!ST->hasNEON() || NumElements.isScalable())
+ return false;
----------------
It looks like there is at least some test coverage missing, e.g. I think we need a test with scalable vectors and with different element types other than double.
