13:26:09stassatswell, i'm not really going to look into it
13:26:24stassatsas i don't really bother with documentation

14:57:49mgskHi, all. Trying to understand the disassembly produced by SBCL. I've noticed that if I increase a constant by 1 then the assembly shows a change of x2 to what it was before. Is the low bit being used for something? Demonstrated in https://gist.github.com/notmgsk/a354e38e6dcf5e7e6169273e36839e3c
14:59:23ShinmeraThe low bit is the tag that distinguishes integers from other kinds of objects.
16:49:06ShinmeraIt seems in recent SBCLs trying to call sb-di:debug-source-form results in an error about SB-C::DEBUG-SOURCE-FORM being undefined. Did the interface for debug-source-forms change or something? When I look at the def!struct the field is still there so I'm confused about why the reader would be undefined.
16:49:38stassatsit has changed, and the field is not there
16:49:53ShinmeraOh, then I must have old sources lying around somehow-- sorry.
16:50:09ShinmeraStill should remove that export from sb-di, though.
