[llvm-dev] [llvm-commits at lists.llvm.org: Re: [llvm] 2dea3f1 - [SVE] Add new VectorType subclasses]

[Joerg Sonnenberger via llvm-dev]

Bringing this up on llvm-dev for more general attention.

The problem here is two fold:

(1) Reuse of enumeration values is just a major no-go.
(2) I'm not sure why the existing vector types had to be killed
completely.

But something clearly has to be done here. This majorly affects e.g.
Mesa.

This seems to have basically broken both ABI and API of llvm-c.
