This is different from the argument passing convention which puts the first float argument in %f1. With this patch, all returned floats are treated as if the 'inreg' flag were set. This means multiple float return values get packed in %f0, %f1, %f2, ... Note that when returning a struct in registers, clang will set the 'inreg' flag on the return value, so that behavior is unchanged. This also happens when returning a float _Complex. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199028 91177308-0d34-0410-b5e6-96231b3b80d8
