This patch fixes the PPC calling convention to handle returns of _Complex float and _Complex long double, by simply increasing the number of floating point registers available for return values. The test case verifies that the correct registers are loaded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172733 91177308-0d34-0410-b5e6-96231b3b80d8
