| sena_kun | anyone around with knowing how to write C carefully to help with dyncall? | 17:39 | |

| Voldenet | I'd help, but I have no idea to code carefully ;/ | 18:49 | |

| Voldenet | maybe that's a silly question, but does anything actually use dlGetLibraryPath(NULL, …) except github.com/MoarVM/dyncall/blob/b3a...ain.c#L158 ? | 19:36 | |

| sena_kun | not really, but something can use dynload_plain and... well, it was decided it's better to wait a response from official maintainer. | 19:38 | |
|

| Voldenet | otherwise I'm not sure how to test it in context of compiling moarvm, it might be better to run test/dynload_plain.c instead | 19:42 | |
| nine | The constants involved in the offending code seem to be totally undocumented and the whole thing is highly platform dependent. I'd just not dare to fix it myself. | 19:44 | |
| Voldenet | to fix this probably `#if (defined(RTLD_DI_LINKMAP) || defined(OS_SunOS)) && !defined(DL_USE_GLIBC_ITER_PHDR)` should have RTLD_SELF added as a requirement | 20:40 | |
| because there's "else" section for environments that support nothing ;) | 20:41 | ||

| lizmat | and another Rakudo Weekly News hits the Net: rakudoweekly.blog/2020/02/24/2020-...red-noise/ | 21:37 | |
| jnthn | \o/ | 21:39 | |
| lizmat++ # wow, busy week | 21:44 | ||
| MasterDuke | brrt: how would we create templates for a lot of the sp_* ops? the interp code and lego jitted versions have loops in them | 22:12 | |
| tellable6 | MasterDuke, I'll pass your message to brrt | ||
| jnthn | MasterDuke: Which ones, ooc? | ||
| I don't think many of 'em have loops... Conditionals maybe | 22:13 | ||
| MasterDuke | sp_getlex_o was the one i was just looking at | ||
| jnthn | How does it do the non-specialized getlex? | 22:14 | |
| MasterDuke | dunno, there is no getlex_o | ||
| but the regular getlex template is just `(template: getlex (copy $1))` | 22:16 | ||
| and the other getlex_(ni|nn|ns|no) just call MVM_frame_find_lexical_by_name | 22:17 | ||
| *other templaes | |||
| **templates | |||
| fwiw, a spesh log i was just looking at had these as the reason for the next most frequent expr jit bails: sp_bindlex_os, sp_getvt_o, sp_getvc_o, sp_fastbox_i_ic, getattr_o, sp_getlex_ins, sp_get_i64, sp_fastbox_bi_ic, assign, sp_bindlex_in, bindattr_o | 22:21 | ||
| jnthn | I suspect sp_getvt_o, sp_getvc_o and sp_get_i64 are the easiest of them | 22:22 | |
| Well, the last one is in theory trivial | |||
| Others a bit less so | 22:23 | ||
| MasterDuke | heh, i was just looking at sp_get_i64 and i'm not sure how to do that somewhat complicated cast in a template | ||
| but maybe it's not needed | |||
| i've seen sp_fastbox_i_ic in a bunch of spesh logs | 22:25 | ||
| Voldenet | i've kind of fixed the musl issue in dyncall, maybe everything will work now ¯\_(ツ)_/¯ | 23:22 | |

| sena_kun | Voldenet, wrote another email to the maintainer(s) and asked for a review, thanks for your efforts. | 23:56 | |
