...(desirable), or if it's going to be so problematic that I'd be better off implementing an entire new code-generator myself (undesirable). Any other comments or discussion is welcome. All of my work (hardware design and all software) will be publicly and freely available. -- Wesley J.

...part of the data that convinced me that I really could go with a stack machine for the work I'm doing. I'm planning on implementing register allocation based partially on your paper. Actually, I was wondering if any of your lcc implementation work was publicly available. -- Wesley J.

...in a target-specific format that I can easily read from Python, where the I'm implemented the bulk of my actual backend. I'm doing this largely to avoid writing an .ll or .bc parser (which wouldn't be terrible, but I'm not sure how stable those formats really are). -- Wesley J.

Hi. Le duodi 2 frimaire, an CCXIV, Wesley J. Landaker a ?crit?: > speexenc always crashes on amd64; here is an example, and lots of info: I tracked this bug a bit further than you.

...step? Anyway, I'm just trying to make sure I'm taking the right approach before I run head first into any dead ends. Ultimately, I'd rather do things "right" than "fast", since in my experience, "right" takes less time in the long run. ;) -- Wesley J.

...des a head start for chosing stack allocation candidates. For example, PHI-nodes are obvious candidates for edges in the flow-graph. I would be interested to see how good SSA-form is for stack allocation, as that was my intended direction if I had stayed longer at York. Cheers, Mark. Wesley J.

from the Agile Book, i see i can set the absolute session expiry time via: ActionController::CGIRequest::DEFAULT_SESSION_OPTIONS[:session_expires] however, I don''t see anything about what the actual default setting is when a session is created. also, is there a way to set the expiration to happen when the browser is closed? in PHP, this can be accomplished using

I''m really lost on this issue. Do I need to reinstall rails / gems? The rest of my rails setup seems to be working. I just can''t run dispatch.fcgi. (Details in original message below). I have no idea how to troubleshoot this. I''m not even positive it is supposed to be runnable from the command line. I found a troubleshooting guide that implied it was supposed to
