New Revision: 205044
URL: http://llvm.org/viewvc/llvm-project?rev=205044&view=rev
Log:
OnDiskHashTable: Use EndianStream.h to write little endian ostreams
Rather than rolling our own functions to write little endian data to
an ostream, we can use the support in llvm's EndianStream.h.
No functional change.
