valgrind
http://wiki.netbsd.org/projects/project/valgrind/ sketches a project for porting valgrind, but gives tech-kern as its contact address. Surely that's not right? In passing, the difficulty will vary, substantially I expect, with the port(s) it's targeted for. I spent a while trying to implement valgrind on the NetBSD/sparc I use and ended up collapsing that effort into my userland SPARC emulator instead; handling a restore in the delay slot of a jmpl, a common thing in function epilogues, looked like more of a headache than adding the functionality to the emulator. (It's found one bug in libc already, back in July 2021 IIRC.) Perhaps I just need a better approach /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTMLmo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

Not all that exotic. AIUI it's just a Lisp dialect. (A slightly odd one in that it eliminates the distinction between value cells and function cells, but back when I looked at it that was about the oddest thing about it.) /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTMLmo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

Isn't this what SWIG tries to do? One might argue about how well it does it. As for Scheme, I thought that's a programming language, and a rather exotic one at that. Or do you mean something else called "scheme"? paul
about langage neutral
Hello tech-kern, I'm discorvering the article about language-neutral-interfaces for system calls. http://wiki.netbsd.org/projects/project/language-neutral-interfaces/ That is a very interesting topic. IMHO scheme language is well suited to answer the issue. Are you interested in more discussion around that topic? Best regards José Bollo
