[llvm-commits] CVS: llvm/include/llvm/Bitcode/ReaderWriter.h

[Chris Lattner]

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.
