Remove seemingly unneeded and harmfull ldrpath from build

The @prefix@/share/perl6/site/lib directory does not even exist on a normal installation of rakudo, nqp and moarvm. "@/libdir" does not seem to be needed either as even with it removed, everything seems to work just fine. Removing because rpath is prohibited on Fedora and strongly discouraged on openSUSE.		 08:33

samcv hi having a problem. getting, can't find moar.so 09:06
used perl Configure.pl --prefix="$HOME/perl6"
pretty sure that's what i used before, i mean that's where i have all my moar/nqp/rakudo things
am I doing something wrong? 09:07
nqp said my moar was too old, so i pull'd and then ran make again... and then broke :( 09:08
nine, you broke my Moar ._. 09:10
reverted that last commit. and works fine
just read through all the scrollback hah. looks like others had problems 09:13

dogbert17_ heh, "Must not GC when in the specializer/JIT" 09:54
this I haven't seen before 09:55
jnthn Yeah, that was added last week 09:56
To panic instead of corrupt memory :)
Also, the stack trace of the point in panics will be useful for fixing it :) 09:57
dogbert17_ jnthn: will this do as report material? gist.github.com/dogbert17/4c7d21ce...11cf3c3260
timotimo oooh, demand_extop, eh? 09:58
because it locks + unlocks the mutex?
i expect we'd mark a thread blocked before and unblocked after spesh anyway, right? 09:59
at least ... we probably should? except spesh is supposed to be blistering fast anyway :P
jnthn dogbert17_: Yup 10:00
dogbert17_ cool, I'll add it as a MoarVM issue 10:01
10:05 pyrimidine joined
dogbert17_ btw, are there any other flags apart from FSA_SIZE_DEBUG and MVM_GC_DEBUG that might be useful to turn on for bug hunting purposes? 10:10
timotimo depends on what kind of bug you're hunting 10:12
if there is/you're suspecting a spesh bug, there's a tool that'll help identify the offending frame for you 10:13
jnthn There's also various others that turn on extra debug output
But you need to know what kind of problem you're looking at for them to be much use
Doubly so given extra output introduces timing effects that can hide certain problems you might be hunting 10:14
dogbert17_ thx for the explanantion, I guess I'll stick with the ones above for the time being then :-)
jnthn For example, there's ways to turn on logging output for GC orchestration and deopt 10:15
Though both produce a decent amount of into that is likely to be meaningless for most bug hunts 10:16
dogbert17_ ok, I'll definitely stick to the above two then, at least until they are exhausted :-) 10:17
timotimo oh, hm, it's more nuanced than setting gc to blocked when spesh runs 10:24
because we do have many spots that have interactions with the gc, such as log entries 10:25
and spesh slots
jnthn Far more 10:28
The spesh rule is that GC never takes place while it's running
timotimo right. so we'll need an API (or maybe only usable by spesh? though extops can also define spesh) that locks and unlocks mutexes without doing the blocked/unblocked thing 10:30
jnthn It's not that simple 10:31
The holder of the mutex might have decided to do GC
Then deadlock
timotimo ugh. 10:33
.o( but i thought acquiring a mutex marks a thread as blocked anyway? ) 10:46

Remove at least the obsolete path from ldrpath

As it seems like we still need the @libdir@ rpath, the non-existing
  @prefix@/share/perl6/site/lib can at least still be removed so it will
not cause any future confusion and to solve at least half the problem.		 12:15

SmokeMachine Any one have any idea what could be causing this? gist.github.com/FCO/bb1bb1c0285fcf...8789beb21f 13:25
[Coke] open an RT with both the source and the bt. 13:26
SmokeMachine [Coke]: but the source is too big... I'm trying to reduce it... 13:27
timotimo SmokeMachine: att he point of an explosion, you can "call MVM_print_backtrace(tc)" (or what it's called) and get a stack trace from inside your program 13:28
that can help guide the golfing effort
SmokeMachine timotimo: No symbol "MVM_print_backtrace" in current context. 13:37
timotimo then it must be MVM_dump_backtrace
nine yep it's MVM_dump_backtrace
also you may have to up a couple of times 13:38
timotimo not in that stack trace, though, as it's inside a gc_mark function

timotimo: worked! \o/ ^^ 13:44
looks that's an error on (|) op 13:53
timotimo it's quite unlikely that it has anything to do with (|) itself 14:15
probably something between then and the previous GC run?
