Hi,

 Thanks for your mention.

 It’s so clear & simple, there is no convention for vector args & return of function ?
 also, according our long time designed cpu experiments, there should be some 

 callee saved vector registers for performance across some complicated function calls, right ? :)

 Any considers or details for excluding like vector args ?

Note this is the convention for normal C ABI calls; a separate convention will be adopted for vector millicode calls.
