anything about disk I/O itself. This greatly simplifies its interface - eliminating the need for the ReaderWrappers.cpp file. This adds a new option to llvm-dis (-bitcode) which instructs it to read the input file as bitcode. Until/unless the bytecode reader is taught to read from MemoryBuffer, there is no way to handle stdin reading without it. I don't plan to switch the bytecode reader over, I'd rather delete it :), so the option will stay around temporarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36554 91177308-0d34-0410-b5e6-96231b3b80d8
