Detailed Description

BitstreamReader - This class is used to read from an LLVM bitcode stream, maintaining information that is global to decoding the entire file. While a file is being read, multiple cursors can be independently advanced or skipped around within the file. These are represented by the BitstreamCursor class.

void llvm::BitstreamReader::CollectBlockInfoNames ( )

const BlockInfo* llvm::BitstreamReader::getBlockInfo ( unsigned  BlockID ) const

inline

getBlockInfo - If there is block info for the specified ID, return it, otherwise return null.

bool llvm::BitstreamReader::hasBlockInfoRecords ( ) const

inline

hasBlockInfoRecords - Return true if we've already read and processed the block info block for this Bitstream. We only process it for the first cursor that walks over it.
