mircea_popescu: hey ave1
ave1: goodmorning, I was digesting te logs
ave1: and read all the gnat problems
ave1: I was working on getting a cuntoo up (which is going slow, I need to relearn to build a kernel, this used to be a lot easier 20 years ago)
ave1: I'll park that and start running the gnat build script.
mircea_popescu: ave1 did you ever run a sjlj version ?
ave1: not yet, I'm now trying to get the build up and running
mircea_popescu: ah. ok.
mircea_popescu: well, if you don't have experience with it or anything, it's not urgent -- can continue with cuntoo, can switch to this, either way.
ave1: diana_coman, re http://btcbase.org/log/2019-02-15#1896922, all the links worked this morning, could you tell me which one failed for you?
a111: Logged on 2019-02-15 16:12 diana_coman: hm, full replica might require I upload somewhere the tarballs too since at least 1 link was broken ; anyways, it's with http://ave1.org/2018/building-gnat-on-musl-now-always-static/ + taken out the download script for ada2016 because broken link + added GCC_CONFFLAGS="--enable-sjlj-exceptions" to extraconfig.sh ; set path to point to existing and working adacore 2016 gnat + put all tarballs in their place
ave1: O wait, I tried with: http://ave1.org/2018/building-gnat-on-musl-no-more-usrincludex86_64-linux-gnu/
diana_coman: ave1, it was the link that downloaded the gcc src and stuff for adacore2016 ; after that first fail I just copied my own stuff into tarballs/ , packed properly and never really bothered with the rest i.e. it builds all offline now anyway
diana_coman: update re builds: it built fine with --enable-sjlj-exceptions in place, checked it in the log and yes, it's set; but the result still seems to be build ada code with zcx in fact (i.e. my test code with tasks is STILL hung waiting for them to abort) and if I specify --rts=sjlj to gprbuild it complains that there is no native compiler for ada and so can't do anything; ftr I compared the dirs of my adacore install and it has this specific dir
diana_coman: rts-sjlj with its own adainclude/ and so on; so I am back to my previous obv that this flag per se is apparently not enough
diana_coman: when I say "it built" above I mean specifically those versions: http://ave1.org/2018/building-gnat-on-musl-no-more-usrincludex86_64-linux-gnu/ and http://ave1.org/2018/building-gnat-on-musl-now-with-partial-and-parallel-build-support/ i.e. both static only and previous
ave1: diana_coman, in system-linux-*.ads (in gcc/ada directory) you'll find the line: ZCX_By_Default : constant Boolean := False;
ave1: I'm currenlty building with it set to False, but it is True in the distributed files
bvt: hello. ave1: doesn't makefile.in in gcc-interface tweak it with sed to the necessary value?
diana_coman: ave1, ah, thanks! I'll set it to false and try again then
spyked: http://btcbase.org/log/2019-02-16#1897122 <-- the armv7-armv8 gap is even bigger than x86-x64. armv8 is an entirely new arch, also has 32-bit mode (called aarch32), but that's completely backward incompatible with armv7
a111: Logged on 2019-02-16 00:53 asciilifeform: they're as diff as x86 an' x64
asciilifeform: diana_coman: could plz tar up that built gnat and post ? i have a suspicion ( to get ljmp with old gnat, i had to set include paths on my box )
asciilifeform bbl in 2-3h
mircea_popescu: http://btcbase.org/log/2019-02-16#1897191 << it should, yes.
a111: Logged on 2019-02-16 10:07 bvt: hello. ave1: doesn't makefile.in in gcc-interface tweak it with sed to the necessary value?
diana_coman: oh hey, apparently ave1's find was spot on!
mircea_popescu: nice.
diana_coman: after all the struggle I'm still looking suspiciously at it, lol
asciilifeform: guten morgen diana_coman , mircea_popescu , et al
asciilifeform: diana_coman: oh hey it runs ?
BingoBoingo: Buenas tardes asciilifeform
mircea_popescu: diana_coman does it actually produce sjlj code ?
asciilifeform: http://btcbase.org/log/2019-02-16#1897170 << they have both types ( bezos et al ) neh
a111: Logged on 2019-02-16 02:32 mircea_popescu: so yeah, much like retarded russkis go "oh, we too businessmen, gave $dork state income, now he can buy suit" ( http://btcbase.org/log/2018-03-21#1788430 finest example), the ustards are all "oh, gave computing to wintel, can has tech!!!"
diana_coman: asciilifeform, how did you vivisect that pair of binaries? I'd rather do it to see what came out since otherwise I have only this "oh, now it DOES kill tasks!"
asciilifeform: diana_coman: ida, but objdump -d proc.o will do the job likewise ( in slightly gnarlier format )
mircea_popescu: BingoBoingo do you by any chance recall the princeton "trained psychologist" on okcupid who couldn't spell but was nevertheless doing diagnosing over the phone ?
BingoBoingo: mircea_popescu: I'll have to dig, but it sounds very familiar
asciilifeform: diana_coman: if they dun abort and you want another detailed vivisect, feel free to post'em, i'ma rip'em open after tea
asciilifeform: ( or even if they work )
mircea_popescu: asciilifeform i think she means to learn how it's done.
asciilifeform: mircea_popescu: i hesitate to addict folx to ida, it's a gnarly ball of proprietary liquishit, and needs a toilet box with 'wine' to run etc
asciilifeform: ( 1 of those things for which there aint a complete substitute, sadly, if yer doing serious reversing )
mircea_popescu: diana_coman it's of course cheaper to just ship the object files to him
diana_coman: mircea_popescu yes + I must say I like the idea of "rip'em open after tea" - sounds great; but other than that: I'll try objdump too since after this gnat-adventure I'd rather have some way to look inside it
asciilifeform: diana_coman: if , like asciilifeform , you grew up on intel asm syntax, you can objdump -M intel -d proc.o
asciilifeform: diana_coman: are we sawing'em open because it dun actually abort, or simply to compare with old gnat's sjlj , tho ?
asciilifeform brb,tea
diana_coman: asciilifeform, they abort; we are sawing them open because I don't trust it anymore re "what does it actually do exactly"
diana_coman: i.e I want to see what did it do
mircea_popescu: it has lied before...

mircea_popescu: o damn.
mircea_popescu: she was from harvard not princeton! my bad.
BingoBoingo: AHA, the perils of searching for keywords so strongly associated with constant failure
mircea_popescu: you know ? but ty!
BingoBoingo: Princevard, harMIT, they all blend together
diana_coman: asciilifeform, here it is: ossasepia.com/available_resources/sjlj_testtasks.tar.gz
diana_coman: I added a delay in there before the final check of tasks
asciilifeform: diana_coman et al : http://www.loper-os.org/pub/misc/feb_16_tasks_o.html
asciilifeform: ^ near as i can tell, it uses exactly same scheme as the old gnat's sjlj-mode handlers
asciilifeform: nao this is not a complete answr to 'what does it do, EXACTLY' cuz that also ropes in the ~2MB of standard lib
asciilifeform: but the proggy .o seems to be exactly as expected ( if diana_coman has time, can try with the old gnat and see if in fact bitwise-same or not )
asciilifeform still wakin' up, misread http://btcbase.org/log/2019-02-16#1897225 as 'illiterature'

mircea_popescu: just about.
mircea_popescu: the "textbooks" this generation of mostly female, mostly useless college kids don't read are very fucking different from the textbooks we didn't read twenty years ago.
asciilifeform still got good # of the latter
mircea_popescu: as per the "this is the shop where we don't have talapia. the shop where they don't have salmon is down the street"
asciilifeform: incidentally, re the posted htm, no yer box aint broken, there really aint any clickable links therein (why not? in what's undisputably world's best disasmer ? cuz world's best disasmer is actually not so great , compared to what's obviously possible )

mircea_popescu: asciilifeform shouldn't eggog, should redirect you to explainy.
asciilifeform: mircea_popescu: seems to redirect to random article
asciilifeform: ( try it, by clicking from phf's log )
mircea_popescu: well, i did what the article proposes, set my referrer to trilema permanently, so i always see trilema pics.
mircea_popescu: asciilifeform check it out, my htaccess got fucked meanwhile.
mircea_popescu: should be fixed now.
asciilifeform: loads via the article, as intended
mircea_popescu: yeah, but if you try it solo should take you to http://trilema.com/2019/trilema-images-no-longer-showing/

bvt: http://btcbase.org/log/2019-02-12#1895598 << i'd like to briefly report on this: at this point i'm sure that there is a race condition. i'll do a post tomorrow morning on it, but short summary is
a111: Logged on 2019-02-12 23:36 mircea_popescu: but seems he ALSO found a race condition in the handlers ?
bvt: unwinding stack for exceptions requires taking locks https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=libgcc/unwind-dw2-fde.c;h=24b4ecee68c17e1701c4482580e449b03a4e6fe9;hb=HEAD#l1046
bvt: which is broken with static linking due to usual 'creativeness' of gnu folx https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=libgcc/gthr-posix.h;h=88cbc23937ec20b15b35c5adb7f9983282c6f084;hb=HEAD#l247
mircea_popescu: cool.
bvt: http://bvt-trace.net/src/test_task_exceptions.tgz - test source for those who want to test. to be run as 'while true; do echo -n .; ./adatests >/dev/null || break; done' -- should not take too long to have it segfault.
bvt: (still tested only with gnat2017, but this is a different story; i see no reason to believe that ave1gnat does not have the same issue)
mircea_popescu: me either.
bvt: i.e. with static linking, all locks are compiled into noops.
bvt: i still have no solution for this, afaik musl authors solved the problem for fortran and c++, but gnat seems to lack equivalent knob
mircea_popescu: how did they solve it for c++ ?
bvt: they disabled weak symbols for c++/fortran components, http://port70.net/~nsz/musl/gcc-5.3.0/0004-gthr.patch
bvt: however i don't understand if this is possible only to achieve only for gnat components, and when i do it globally, i get 'undefined symbol' when linking with libgcc
asciilifeform: bvt: compiled into noops << where ? in stdlib ? ( or can point in http://btcbase.org/log/2019-02-16#1897234 ?? )
