[PATCH] D133116: [AArch64][SVE] Optimise repeated floating-point complex patterns to splat

[Matt Devereau via Phabricator via llvm-commits]

MattDevereau updated this revision to Diff 474547.
MattDevereau added a comment.

Added test `dupq_f32_repeat_complex_unordered` and `dupq_f32_repeat_complex_rev_unordered` which assert the simplifiction does not trigger when insert_vector_elt's indices are not incremental
Added test `dupq_f32_repeat_complex_rev` to assert the simplification takes place when starting from an insertelement into the final vector index.
Added tests `dupq_f16_repeat_complex_omit_pair` the simplification does not trigger when vector elements are unknown.
Added tests `dupq_f16_repeat_complex_mismatched_front`, `dupq_f16_repeat_complex_mismatched_end` and `dupq_f16_repeat_complex_mismatched_middle` to verify the simplifaction considers the full range of elements
