Detailed Description

StringToOffsetTable - This class uniques a bunch of nul-terminated strings and keeps track of their offset in a massive contiguous string allocation.

It can then output this string blob and use indexes into the string to reference each piece.

EmitCharArray()

void llvm::StringToOffsetTable::EmitCharArray ( raw_ostream &  O )
