We've got at least one person here with decades of experience handling
complex operations in compilers who thinks LLVM IR should absolutely
have native support for complex, FWIW. I don't have enough experience
with it myself to make a definitive statement but I can certainly see
advantages to it.
Most of us here also think that LLVM IR should absolutely have native
support for predication/masking. :)
As for matrices, I again can see the advantages but have no practical
experience to draw upon. But some people at Apple seem to think it's
advantageous and I'm interested in learning more.
