2007-05-06remove this file for now, we can bring it back from cvs if we need it inChris Lattner

2005-05-13Make sure that decompression checks for the case that bzip2 returnsReid Spencer
BZ_OK (meaning more data is expected) but there is no more input data. In this case, the input file is probably truncated. Generate an exception that indicates this case when its detected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21926 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-29This file was schizophrenic when it came to representing sizes. In someChris Lattner
cases it represented them as 'unsigned's, which are not enough for 64-bit hosts. In other cases, it represented them as uint64_t's, which are inefficient for 32-bit hosts. This patch unifies all of the sizes to use size_t instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19918 91177308-0d34-0410-b5e6-96231b3b80d8
2005-01-29After reading in a bc file, trim the resultant buffer down to what weChris Lattner
really need. This reduces 4M of memory consumption reading 176.gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19916 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-30Up the compression threshold to 64K so we avoid it for all but the largestReid Spencer
bytecode files. This should help linking substantially. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18378 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-19Allow this to compile even on machines that HAVE the bzlib library but doReid Spencer
NOT have the bzlib.h header file. Go figure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17989 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-14Implement the high level interface to make (de)compression easier.Reid Spencer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17775 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-09Tune compression:Reid Spencer
bzip2: block size 9 -> 5, reduces memory by 400Kbytes, doesn't affect speed or compression ratio on all but the largest bytecode files (>1MB) zip: level 9 -> 6, this speeds up compression time by ~30% but only degrades the compressed size by a few bytes per megabyte. Those few bytes aren't worth the effort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17647 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-04Excise the ill-advised RLCOMP compression algorithm and simply leave theReid Spencer
previously temporary NULLCOMP implementation that merely copies the data verbatim without compression. Also, don't warn if there's no compression library as that is taken care of during configuration time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16654 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-04Add a context for the callback so different compression scenarios can beReid Spencer
