According to the Sparc V8 ABI, complex numbers should be passed and returned as pairs of registers: https://docs.oracle.com/cd/E26502_01/html/E28387/gentextid-2734.html This fix ensures this is the case. Without this, complex numbers are returned as a struct of two floats, which breaks the ABI rules. Differential Review: http://reviews.llvm.org/D20955 llvm-svn: 272148
