[llvm-commits] [llvm] r44200 - in /llvm/trunk/include/llvm/Bitcode: Deserialize.h Serialize.h

New Revision: 44200

URL: http://llvm.org/viewvc/llvm-project?rev=44200&view=rev
Log:
Changed implementation of Serialize::EmitDiffPtrID and
Deserialize::ReadDiffPtrID to read and emit bools instead of unsigned
integers. This should result in a nice space optimization once we have
"auto-abbreviation" generation in place.
