I have sent a little bit earlier a series of patches which describes my implementation of the support for native complex operations. There are 8 generic patches and 1 experimental x86 patch which exploits a portion of the added features. The initial message called "[PATCH 0/9] Native complex operations" [1] explains the implementation details and illustrate it with some examples, mainly on KVX because the backend implements all the features and the ISA has native complex instructions. Some implementation details need to be discussed, especially concerning vectors of complex elements and the merge with the work from Arm.
