Owen Anderson	3a9e7690ba	Use a more efficient lowering of uint64_t --> float that can take advantage of hardware signed integer conversion without having to do a double cast (uint64_t --> double --> float). This is based on the algorithm from compiler_rt's __floatundisf for X86-64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115634 91177308-0d34-0410-b5e6-96231b3b80d8	2010-10-05 17:24:05 +00:00
