RFR: 8287794: Reverse*VNode::Identity problem [v4]

Thu Jul 28 05:41:42 UTC 2022

> 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
