New Revision: 183290
URL: http://llvm.org/viewvc/llvm-project?rev=183290&view=rev
Log:
Heed ABIArgInfo::getInReg() for return values.
The 'inreg' attribute can also be applied to function return values in
LLVM IR. The SPARC v9 backend is using the flag when returning structs
containing 32-bit floats.
