New Revision: 127871
URL: http://llvm.org/viewvc/llvm-project?rev=127871&view=rev
Log:
Initialize the only-used-with-PPC-double-double parts of the APFloat class. This
makes valgrind stop complaining about uninitialized variables being read when it
accesses a bitfield (category) that shares its bits with these variables.
