The inalloca parameter has to be the only parameter passed in memory. Changing the convention to fastcc can break that. At some point we should teach global opt how to optimize ABI attributes like inalloca and maybe byval. These attributes are mainly used to match C ABIs. They are harder for LLVM to optimize and they don't always generate the best code. Fixes PR38487 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@339360 91177308-0d34-0410-b5e6-96231b3b80d8
