Extended Description

Recently tried to compile an autogenerated metal shader and got an internal compiler error and a notice that I should report a bug. The used metal shader is assigend as attachment and here comes the stack trace:

crash in Apple's "metal" shader compiler

As "metal" is not part of the LLVM project, but a tool created by Apple for their Metal API, I think that this bug should be filed with Apple at https://bugreport.apple.com/ [*]

I'm closing this as invalid. However please feel free to reopen if you disagree.

[*] Despite the misleading "PLEASE submit a bug report to http://llvm.org/bugs/" (which Apple should really fix).
