[llvm-commits] CVS: llvm/lib/Bytecode/Archive/Archive.cpp ArchiveReader.cpp ArchiveWriter.cpp

[Chris Lattner]

Changes in directory llvm/lib/Bytecode/Archive:

Archive.cpp updated: 1.15 -> 1.16
ArchiveReader.cpp updated: 1.48 -> 1.49
ArchiveWriter.cpp updated: 1.33 -> 1.34
---
Log message:

push bytecode decompressor out through APIs.  Now the bytecode reader
api's look like this:

ModuleProvider *getBytecodeModuleProvider(
  const std::string &Filename,  ///< Name of file to be read
  BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
  std::string* ErrMsg = 0,      ///< Optional error message holder 
  BytecodeHandler* H = 0        ///< Optional handler for reader events
);

This is ugly, but allows a client to say:

  getBytecodeModuleProvider("foo", 0);

If they do this, there is no dependency on the compression libraries, saving
codesize.
