clang-p2996/llvm/test/CodeGen/AMDGPU/cc-update.ll
Matt Arsenault 729bf9b26b AMDGPU: Enable fixed function ABI by default 
Code using indirect calls is broken without this, and there isn't
really much value in supporting the old attempt to vary the argument
placement based on uses. This resulted in more argument shuffling code
anyway.

Also have the option stop implying all inputs need to be passed. This
will no rely on the amdgpu-no-* attributes to avoid passing
unnecessary values.
