When using the ARM AAPCS, HFAs (Homogeneous Floating-point Aggregates) must be passed in a block of consecutive floating-point registers, or on the stack. This means that unused floating-point registers cannot be back-filled with part of an HFA, however this can currently happen. This patch, along with the corresponding clang patch (http://reviews.llvm.org/D3083) prevents this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208413 91177308-0d34-0410-b5e6-96231b3b80d8
