git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10874 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-15Change all of the bytecode reader primitives to throw exceptions instead ofChris Lattner
returning error codes. Because they don't return an error code, they can return the value read, which simplifies the code and makes the reader more efficient (yaay!). Also eliminate the special case code for little endian machines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10871 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-14Version 1.2 now supports encoding strings as a special case, to avoid havingChris Lattner

2003-12-22Reverted back to revision 1.11. The previous fix doesn't really fixJohn Criswell
anything; it just causes the bug to go dormant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10585 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-20Fix PR#193.John Criswell
Modified ReadArchiveBuffer() so that it dynamically allocates the std::string object used to hold the bytecode object file's name. This is necessary because it is passed by reference to the new Module that is allocated to represent the bytecode object, and previously we were using a std::string that disappeared on function exit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10565 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-11In getObjectType(), doxygenify comment, and take a pointer to theBrian Gaeke
beginning of the archive member data as an argument. Get rid of ParseLongFilenameSection(), which is dead. In ReadArchiveBuffer(), implement support for 4.4BSD/MacOSX long filenames. This is kind of invasive, because they prepend the long filename to the archive member data, and then lie about the size. So we have to keep track of the real size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10392 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-01Emit & read more compressed bytecode by not emitting a bytecodeblock forChris Lattner
each basic block in function. Instead, just emit a stream of instructions, chopping up basic blocks based on when we find terminator instructions. This saves a fairly substantial chunk of bytecode space. In stripped, sample cases, for example, we get this reduction in size: 197.parser: 163036 -> 137180: 18.8% reduction 254.gap : 844936 -> 689392: 22.6% 255.vortex: 621724 -> 528444: 17.7% ... Not bad for something this simple. :) Note that this doesn't require a new bytecode version number at all, though version 1.1 should not need to support the old format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10280 91177308-0d34-0410-b5e6-96231b3b80d8

* Strength reduce several data structures which were left over from the "bad old days" * Minor efficiency improvements * Major efficiency improvement: In BytecodeParser::insertValue, do not allocate a new ValueTab entry just because some value exists with a large type. This dramatically reduces the number of allocations/deallocations performed by the bytecode reader, and speeds up parsing of Kimwitu++ from 34s to 17s.

2003-10-10Ok, the "fix" for this is to do a real associative container. Symbol tablesChris Lattner
