Changes in directory llvm/include/llvm/Bitcode:
ReaderWriter.h updated: 1.1 -> 1.2
---
Log message:
Switch the bitcode reader interface to take a MemoryBuffer instead of knowing
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.
