I've built with ABCL fairly recently (it was a Linux build though) 2016-01-11T08:16:14Z loke: And to be honest, the error doesn't look like it's related to the xc-host, but what do I know? :-) 2016-01-11T08:16:44Z loke: There isn't even a 'genesis' directory to be found.

The instructions in make.sh for doing a cross-build are out-of-date, aren't they? 2016-01-11T08:18:47Z Xof: everything after that is irrelevant 2016-01-11T08:21:35Z loke: nyef: Can't be very much out of date, since I did it less than 6 months ago. 2016-01-11T08:23:31Z igajsin joined #sbcl 2016-01-11T08:24:30Z nyef: Since October 22, 2011, apparently. 2016-01-11T08:24:52Z nyef: commit 7d407220e18f65637835ed034894654ca55a4bcd 2016-01-11T08:25:08Z loke: Are you referring to the content of the INSTALL file, or the actual code that does the cross-build? 2016-01-11T08:25:33Z nyef: I'm referring to the comments in make.sh about how to do a cross-build. 2016-01-11T08:26:02Z loke: OK, I didn't read those.

I am using a C library wrapper I wrote https://gitlab.com/mordocai/cl-bearlibterminal and this happens with the hello world example. Any advice on tracking this down? 2016-01-15T05:52:50Z mordocai: I basically feel I'm at the point that I should strace or gdb or something but but I don't have experience doing that with lisp images yet so if that's what I need to do a guide to such would be helpful 2016-01-15T05:54:14Z karswell quit (Ping timeout: 276 seconds) 2016-01-15T05:54:15Z sjl quit (Ping timeout: 260 seconds) 2016-01-15T06:00:01Z flip214: mordocai: don't think that strace will help here; you'll need GDB. 2016-01-15T06:00:30Z mordocai: flip214: Kk, yeah. Do you know of any docs on effectively using gdb with sbcl + cffi? 2016-01-15T06:00:36Z mordocai: Or should it be straightforward? 2016-01-15T06:00:41Z mordocai: I know it was awful when I tried it with ruby 2016-01-15T06:01:00Z flip214: but I don't know enough about SBCL internals to guide you there, sorry. 2016-01-15T06:02:51Z mordocai: Hmm... got a segfault when I just did gdb sbcl run 2016-01-15T06:02:52Z flip214: perhaps ltrace can show some misuse of the library, or wrong CFFI bindings 2016-01-15T06:03:08Z flip214: yeah, you need to ignore that and other signals. 2016-01-15T06:04:23Z flip214: handle SIGXCPU SIG33 SIG35 SIGPWR nostop noprint 2016-01-15T06:04:33Z flip214: mordocai: http://sourceforge.net/p/sbcl/mailman/message/29106415/ 2016-01-15T06:04:49Z flip214: see Nikodemus' post. 2016-01-15T06:06:48Z mordocai: Ah thanks. Idk how to ignore signals, guess I should learn! 2016-01-15T06:09:06Z mordocai: Do you know how I would add --with-ud2-breakpoints for the build? I'm used to just using ./make.sh 2016-01-15T06:14:44Z flip214: simply pass to make.sh 2016-01-15T06:15:00Z flip214: and ignoring signals is done with a "handle ... nostop noprint" line, like I pasted above. 2016-01-15T06:16:37Z mordocai: I must be passing it wrong. I've tried various variations of ./make.sh --with ud2-breakpoints but i keep getting malformed feature toggle 2016-01-15T06:20:18Z flip214: there's no space between "--with" and "ud2-breakpoints" 2016-01-15T06:20:23Z flip214: there's a dash 2016-01-15T06:20:52Z mordocai: Ah that was my mistake thanks, compiling now. Sorry about that, I should probably be sleeping but I want to figure this out :P 2016-01-15T06:24:52Z flip214: never type when copy-paste is available ;) 2016-01-15T06:29:53Z mordocai: Seems to be working now with those signals ignored, hopefully i get some useful info 2016-01-15T06:31:21Z flip214: good luck! 2016-01-15T06:43:42Z tcr joined #sbcl 2016-01-15T06:45:53Z Cymew joined #sbcl 2016-01-15T06:53:02Z tcr quit (Remote host closed the connection) 2016-01-15T07:11:35Z zcm joined #sbcl 2016-01-15T07:21:42Z tcr joined #sbcl 2016-01-15T07:31:55Z Xof: loke: it doesn't make sense to add it to SBCL, I'm afraid 2016-01-15T07:32:43Z Xof: consider: (defun foo (x) (let ((y (string #\a))) (if (= (random 2) 1) y (setf (char y 0) x)))) 2016-01-15T07:33:02Z Xof: legal code, but under your transformation would modify a constant string 2016-01-15T07:33:11Z loke: Oh noes.

In my code, I have (string #\Newline).

Massive alien stack allocation? 2016-01-21T19:19:33Z jasom: 100k 2016-01-21T19:19:35Z stassats: so, perhaps we should divorce interrupt context saving and fffc 2016-01-21T19:19:41Z jasom: oh, not 100k 2016-01-21T19:19:52Z jasom: 1MB 2016-01-21T19:20:25Z stassats: though maybe the actual ff bit of fffc does help with backtraces 2016-01-21T19:20:37Z stassats: to be investigated 2016-01-21T19:20:51Z

the debugger to start from the interrupted frames anyway, so all the fancy stuff ffca tries to do is pointless now 2016-01-21T19:21:31Z stassats: s/ffca/fffc/ 2016-01-21T19:22:19Z jasom: My next question is that this only seemed to happen when I had a fairly large amount of data go into the buffer I allocated 2016-01-21T19:22:47Z jasom: so does that mean I'm just now overflowing a heap buffer instead of a stack buffer, or is there something else going on? 2016-01-21T19:22:49Z stassats: sure, how else will it trip the barrier 2016-01-21T19:23:15Z jasom: stassats: I make a foreign call inside the with-foreign-pointer, shouldn't that trip the barrier? 2016-01-21T19:23:34Z stassats: no 2016-01-21T19:24:16Z jasom would think the arguments would be pushed on the stack after the large stack buffer (though maybe not on x86-64) 2016-01-21T19:25:51Z stassats: arguments are not always pushed 2016-01-21T19:26:03Z gingerale- quit (Remote host closed the connection) 2016-01-21T19:26:13Z stassats: but CALL does, but it may be so large it points into the heap => bad things 2016-01-21T19:26:17Z jasom: right; I actually am not at all familiar with the abi of x86-64; I know arm and power much better 2016-01-21T19:26:46Z stassats: or another stack 2016-01-21T19:26:55Z stassats: stack allocation safety is on my todo list 2016-01-21T19:27:04Z stassats: well, if i had a todo list it would be there 2016-01-21T19:27:11Z jasom: well unwind-protect works for me for now 2016-01-21T19:27:25Z jasom: unwind-protect and foreign-alloc that is 2016-01-21T19:28:02Z jasom actually didn't know with-foreign-pointer could stack allocate until I M-. to it 2016-01-21T19:30:00Z stassats: oh, and x86-64 has a separate alien stack, doesn't it? 2016-01-21T19:30:54Z stassats: not the alien control stack, which is the same lisp control stack, but where the number allocation goes 2016-01-21T19:33:34Z stassats: not really the general number stack, but only with-alien stack 2016-01-21T19:49:10Z

2016-01-29T20:40:57Z stassats: two things, there isn't really a constant, second, it can't fold something that calls functions 2016-01-29T20:43:50Z |3b|: ok, was just curious since someone on #clnoobs noticed (apply #'max (list 1 2 3 4 5 6 7 8 9 10)) is constant folded 2016-01-29T20:44:08Z stassats: well, it's transformed to (max 1 2 3 4 5 6 7 8 9 10) 2016-01-29T20:44:48Z |3b|: that's through the

constant" rather than using the specific term "constant folded" 2016-01-29T20:45:48Z stassats: |3b|: no, define-source-transform would be too primitive for that 2016-01-29T20:47:52Z stassats: it's done in defoptimizer (values-list optimizer) 2016-01-29T20:56:23Z stassats: i think i have an easy solution to constant folding callable functions 2016-01-29T20:57:53Z |3b| has no actual use for it,

2016-01-29T21:29:19Z stassats: but that was wrong too 2016-01-29T21:29:29Z stassats: the problem was that constant-fold-call-p wasn't called at all 2016-01-29T21:32:27Z attila_lendvai joined #sbcl

stassats: is it worth it? nah 2016-01-29T21:38:31Z stassats: folding reduce/find/etc is probably not worth it either, but it's just trivial to do 2016-01-29T21:39:53Z stassats: no tests failed, at that 2016-01-29T21:45:46Z stassats: i now think that the CALL attribute is not needed at all 2016-01-29T21:46:14Z stassats: and #'known-fun is not considered to be a constant, but it can be folded anyway 2016-01-29T21:48:09Z stassats: ok, CALL is useful when it checks for for the function argument to another foldable-call 2016-01-29T21:51:27Z |3b|: so it won't fold (reduce #'+ '(+ *) :key 'funcall) ? 2016-01-29T21:51:39Z stassats: it should 2016-01-29T21:51:49Z stassats: oh, funcall, no, it woudln't 2016-01-29T21:51:57Z stassats: i thought it was #' vs ' 2016-01-29T21:52:31Z |3b|:

functions as constants would be TYPE-OF and TYPEP 2016-01-29T21:53:49Z stassats: no, typep would get transformed anyway 2016-01-29T21:54:20Z stassats: constantp and type-of then 2016-01-29T21:56:51Z stassats: and funcall is not marked foldable, but it can, can't it? 2016-01-29T21:57:17Z |3b|: would it get expanded like apply was anyway? 2016-01-29T21:57:34Z stassats: eh, no point, it would be

while previosly it worked, but it failed with UB64 2016-01-31T18:21:14Z stassats: the second one fails now due to fixnum type checks introducing new blocks as well 2016-01-31T18:21:32Z stassats: so,
