* Check in two changes:Chris Lattner2004-01-101-1/+51
| | | | | | | | | | | | | | | | The first change (which is disabled) compactifies all of the function constant pools into the global constant pool, in an attempt to reduce the amount of duplication and overhead. Unfortunately, as the comment indicates, this is not yet a win, so it is disabled. The second change sorts the typeid's so that those types that can be used by instructions in the program appear earlier in the table than those that cannot (such as structures and arrays). This causes the instructions to be able to use the dense encoding more often, saving about 5K on 254.gap. This is only a .65% savings though, unfortunately. :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10754 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10750 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR#193.John Criswell2003-12-202-6/+24
| | | | | | | | | | | 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

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
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10280 91177308-0d34-0410-b5e6-96231b3b80d8
