* Do not bother to emit a BytecodeBlock for an empty symbol table. This commonlyChris Lattner2004-01-101-0/+4
| | | | | | | | | | occurs when the symbol table for a module has been stripped, making all of the function local symbols go away. This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously has 841 functions), which isn't a ton, but helps and was easy. llvm-svn: 10750

* Fix PR#193.John Criswell2003-12-201-3/+12
| | | | | | | | | | 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. llvm-svn: 10565

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. llvm-svn: 10392
* Emit & read more compressed bytecode by not emitting a bytecodeblock forChris Lattner2003-12-014-14/+51
| | | | | | | | | | | | | | | | | | | 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. llvm-svn: 10280

| | | | | | | | | | | | | * 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. This is to help address PR127 llvm-svn: 10085
