I've updated my series of patches. Except bug fixes, two major changes have been done. Everything is explained in the message "[PATCH v2 0/11] Native complex operations" [1]. With Paul Iannetta, we will present our work on complex numbers in gcc at the GNU Cauldron 2023 !

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.
