Hi All,
- This bug fix patch fixes a missing case during reverse[bits|bytes] identity transformation.
- Unlike AARCH64(SVE), X86(AVX512) ISA has no direct instruction to reverse[bits|bytes] of a vector lane hence a predicated operation is supported through blend instruction.
- New IR framework based tests has been added to test transforms relevant to AVX2, AVX512 and SVE.
Kindly review and share your feedback.
Best Regards,
Jatin
