[RISCV] Define vslideup/vslidedown intrinsics and lower to V instructions.

[arcbbb]

Summary

Define vslideup/vslidedown intrinsics and lower to V instructions.

We work with @rogfer01 from BSC to come out this patch.

[arcbbb]

rebase the patch.

[frasercrmck]

The destination register group for vslideup cannot overlap with the source vector register group, so I think we need an extra earlyclobber constraint passed to those pseudos.

[craig.topper]

Please upload patches with git diff -U999999 so that we have full context.

If I'm reading the spec correctly, the offset from the scalar register is not truncated to SEW before applying. So that means the ANY_EXTEND we use in LowerINTRINSIC_WO_CHAIN to extend the operand to XLenVT is incorrect for these intrinsics. We would need a ZERO_EXTEND instead. The C intrinsic spec defines them as taking size_t for offset. We should probably preserve that into the IR intrinsic.

Is the slideup/slidedown type always the same as the element type? Can we use LLVMVectorElementType<0> instead of llvm_any_ty?

I can't delete my previous comment. I think llvm_any_ty here should be llvm_anyint_ty and the tests should use i64 for rv64 and i32 for rv32.

And I guess the llvm_anyint_ty for VL can then just be LLVMMatchType<1> since it also needs to be XLen.

[arcbbb]

Updates:

1. fixed @earlyclobber on vslideup
2. fixed llvm_any_ty to llvm_anyint_ty, and VL to LLVMMatchType<1>
3. fixed tests based on above reviews.
4. rebase to latest master.
5. use LLVMScalarOrSameVectorWidth for mask type.

Thanks!

Drop ExtendOperand. It shouldn't be needed now.

223

Drop ExtendOperand.

llvm/test/CodeGen/RISCV/rvv/vslidedown-rv32.ll

4

This intrinsic name shouldn't have ".i8". It should be ".i32" or dropped.

10

Like wise the test name shouldn't have _i8

[arcbbb]

1. rebased
2. fixed tests based on Craig's comment

LGTM

Should this be below 14.2?
