| Since we talk about code density from time to time, I'd like to open a thread in this section to collect all information, instead of having it spread around in several threads (which also disappear and are difficult to retrieve).
@matthey: I think that you're the most competent and active expert about this topic. Would you like to contribute?
My idea is to create some comments at the beginning of the thread which covers/collect specific topics, which will get updated from time to time. Example: - General information (what's code density, why it's important, etc.) - Benchmarks (state of the art) - Compilers (which ones are best) - Literature (book, academic papers, web sites) - Microprocessors (general information like if the ISA is more or less oriented to code density, if it has specific execution modes for compact code, if it has specific extensions for compact code, etc.) - Motorola 68K corner (anything which is useful about this family, which is not covered by other topics) - Intel IA-32/x86 / AMD x86-64/x64 corner (...) - ARM corner (...) - RISC-V corner (...) - SuperH / J2 corner (...) - Embedded corner (...) - another 5 empty comments for topics which may pop-up in future.
@matthey can you take care of creating and updating those comments? As I said, you're the most competent and also active, so I think that you can contribute much better than me.
A request from my side: please can you share your updated 68K source about this http://deater.net/weave/vmwprod/asm/ll/ll.html ? Looking at your tables in Google Documents the numbers don't match with what mr. Weaver published in that link. |

The topic is a nice idea but I get the feeling that most people here really don't want to know about code density so I'm not very motivated. I really should stop wasting my time here but the interesting court case lured me in.

The last update I sent Dr. Weaver was mostly an improvement of the decompression code by ross on EAB. The assembler files are available on the last 2 pages of the following thread.
http://eab.abime.net/showthread.php?s=e81df9c472e296778e1c2996bf076333&t=85855&page=8
Notice that ross complains in the last post about the statistics not being updated.
