yes, no glibc was in fact a preference, and we got it out, of trb, of eulora, etc. no argument there. |

asciilifeform's 1st step in writing ffa, recall, was to conceive of (and prove) an arithmetic workaround for above. that, right off the bat, cost ~10fold cpu. |
| 11:05 |
asciilifeform |
( and when found that ~despite this~, http://www.loper-os.org/?p=2906 , was pant-shittingly hilarious, how koch still managed to be the tortoise in the race ) |
| |
↖ |
| 11:06 |
asciilifeform |
this is rather like if 2 d00dz run, and the 1 carrying 100kg of lispmachine ends up winning. |
| 11:07 |
mircea_popescu |
anyway, let's draw some quick possible approaches here. |
| 11:07 |
mircea_popescu |
a. we make no standard, every man for his own, but : a.1. ada is the preferred language ; a.2. musl is the preferred standards provider ; a.3. zcx is the preferred exception mechanism ; a.4. static is the preferred build mode. this should come with a design process for candidates evaluation for standardization. |
| 11:07 |
mircea_popescu |
b. ada-sjlj-musl-static is the standard, and we simply don't sign or use anything that doesn't live up to this. |
| 11:07 |
mircea_popescu |
c. ada-?-musl-static is the standard, either zcx or sjlj is acceptable (mostly based on what threading philosophy one embraces), with an obvious preference for zcx if one doesn't thread. |
| |
↖ ↖ |
| 11:07 |
mircea_popescu |
d. ada-zcx-musl-static is the standard for non-threaded programs, we don't standardize threading. |
| 11:07 |
mircea_popescu |
e. something else (among which possible e.1. someone reads and implements dwarf properly ; e.2. someone picks a glibc to grandfather and dedicates himself to cleaning and fixing.) |
| 11:08 |
asciilifeform |
re 'e', i can't picture what'd move anyone with two neurons to rub together to maintain a glibc, that'd be rather like starting a trb from prb 12 (or what is current one) |
| 11:08 |
mircea_popescu |
can import glibc 3.x or w/e. |
| 11:08 |
asciilifeform |
i dun see where drepperism wins in ~any~ version, vs. the ab initio and 10x moar compact musl. |
| 11:08 |
mircea_popescu |
asciilifeform current one prolly v49, note how gcc went from 5 to 8 in 2 years. |
| 11:09 |
mircea_popescu |
asciilifeform but it's not you who has to see, maybe someone sees, what. im certainly not sending you to e.2 |
| 11:09 |
asciilifeform |
mircea_popescu: cuntoo is arguably a realtime test lab for 'what does removing glibc from ~errything~ cost' |
| 11:09 |
asciilifeform |
for instance, emacs has yet to be cured, as i understand |
| |
↖ |
| 11:09 |
mircea_popescu |
so it is. |
| 11:10 |
mircea_popescu |
asciilifeform i very much don't expect you want the prb 12 that is emacs. rewrite yes ? :D |
| |
↖ |
| 11:10 |
asciilifeform |
'd' is arguably mis-statement of problem, a threadless proggy incorporates ~neither~ system |
| 11:10 |
asciilifeform |
( as asciilifeform recently discovered re ffa. it dun thread, and gcc correctly snips out all pertinent coad ) |
| 11:10 |
mircea_popescu |
asciilifeform still gotta build the ada environment ~with something~. |
| |
↖ |
| 11:10 |
asciilifeform |
environment yes. |
| 11:11 |
mircea_popescu |
it was short form for that. |
| 11:11 |
asciilifeform |
aa |
| 11:11 |
asciilifeform |
given this, asciilifeform would go with 'b' + 'we fix the breakages , both as-we-find-'em and proactively ' |
| 11:12 |
asciilifeform |
rather than continuing in a babelized gnat with 'pick yer threader, pick yer stdlib' etc |
| 11:12 |
mircea_popescu |
this pretty much bans glibc, from my unexpert cursory look it dun seem fixable for sjlj. |
| 11:12 |
asciilifeform |
i banned it for all asciilifeform-powered efforts in 2015, and dun miss it. |
| 11:12 |
diana_coman |
re glibc: until now I saw it as tolerated until full tmsr version (whatever that might be, i.e. owned glibc version or musl or whatever) |
| 11:13 |
mircea_popescu |
diana_coman looks like it's going the way of cuntoo-ada-musl, no glibc. |
| 11:13 |
asciilifeform |
diana_coman: the caveat is that i still dunhave a working cuntoo for all asciilifeform-operated irons; e.g. rk is still running barbaric old glibc gentoo |
| 11:13 |
diana_coman |
it does seem precisely so, yes |
| 11:13 |
diana_coman |
and asciilifeform beat me to it |
| 11:13 |
mircea_popescu |
asciilifeform getting an aarch64 musl sjlj going will be a fun task. |
| 11:13 |
diana_coman |
that's precisely why it was tolerated until now afaik: because all sorts not yet fully ported to anything tmsr |

mircea_popescu |
possibly, yeah. |

also, subtle point in http://btcbase.org/log/2019-02-17#1897708 bears belabouring : the point is to standardize ~the tools~, not necessarily (in order) their usage, or end products. the idea is for user to know what to expect if builting a tmsr box, and why he expects that, not necessarily what he can do with it. |

asciilifeform |
possibly i oughta add the detail, that $item is like any other machine i/o-ism -- on bare irons, it writes to the irq table ( whatever shape that has on $irons ) , on unixen it yes uses signals, because wtf else can you do there, on (hypothetical) msdos gnat, will again write to irq table, on boxen without interrupts -- will give eggog on build, what else; etc |
| 12:43 |
asciilifeform |
( incidentally, when asciilifeform speaks of 'iron babel', interrupts are a screamingly concrete example : there is ~no uniformity b/w archs re how they're implemented (does it save regs ? which ? what happens if two interrupts temporally near ? ) or how many , or for what devices, etc ) |
| 12:44 |
asciilifeform |
old msdos hands will recall setting jumpers for e.g. 'soundblaster' irq etc |
| 12:44 |
asciilifeform |
and conflicts. |
| 12:45 |
asciilifeform |
this was 'fixed' by intel (with obscene amt of direct standard authorship by microshit) by making the controller 9000x moar complex |
| 12:45 |
asciilifeform |
aka 'plug and pray' |
| 12:46 |
asciilifeform |
'younger' archs that were baked with decent # of interrupts to begin with, have ~slightly~ less retarded subsystem |
| 12:47 |
asciilifeform |
afaik none of'em, however (with possible exception of sgi's) have semantics such that multiple processors dun share a bottleneck at the interrupt controller |
| 12:48 |
asciilifeform |
( ever wonder why cannot make 'unhangable' os for multi-cpu pc ? this is why ) |
| 12:58 |
asciilifeform |
all of this might seem uninteresting until you realize that this is what sits under all threading, no matter how implemented on os side. |
| 13:00 |
asciilifeform |
( the very need for locking, on software level, for instance, comes from the absence of any sane mechanism for corralling data to particular cpu ) |

asciilifeform |
is this actually in the worx ? or still chalkboard |
| 17:45 |
asciilifeform |
mircea_popescu: thinking about it, kernel is really the starting point for 'get c the hell off the box' -- the e.g. 20% of gnat's standard lib that's in c, is in c strictly cuz of reason illustrate in http://btcbase.org/patches?patchset=udp , i.e. that kernel api doesn't eat sane (e.g. bounded array) parameters, demands liquishit c-istic buffers |
| 17:46 |

entirely possible we'll have to do kernel-and-rest in one gulp |

problem with all this is -- the option's always between trust and knowledge. since we've discovered we can't trust gcc, it follows not only that we now have to write our own ; but that we must maintain the people who know how to write one. |

( for n00bz: ) writing a compiler back-end aint actually hard. asciilifeform & many many other folx, did it ~as homework~ , at school. the hard thing is writing a ~decent~ optimizing backend. |

it's why ~errybody is using gcc's (incl. the folx pretending not to) |
| 18:45 |
asciilifeform |
the other thing that makes backend a bitch is that ~100% of the work has to be done again and again, for each iron. |
| 18:46 |
asciilifeform |
ftr much easier for a sane iron ( with small instruction set ) like mips, than for x86. |
| 18:49 |
asciilifeform |
re bolix back end, i suspect it aint very useful as starting point, because was far ~too easy~ item , in that the iron per se was sane (i.e. performed bounds and type checks, so much of what gcc is stuck doing in soft, was unnecessary ) |

if we had a sane iron, would be similarly easy to produce a back end ( and that's what asciilifeform thinks of as 'ada machine' ) |
| |

asciilifeform |
but presently we haven't such. |
| 18:54 |
asciilifeform |
( this is where i point out, that the fabled 'sane iron' isn't simply a purely aesthetic win to ticke asciilifeform's aestheticles, but in fact substantially cuts down on the complexity of ~all other sane items~ that are to stand on top of it ) |
