timotimo github.com/MoarVM/MoarVM/commit/7df8596eb 13:13
^- lizmat, "Other array ops treat negative indices as counting from the end of the array.
Do the same for the bytestream handling ops.
"
lizmat I guess that answers that question
feels to me that is propagating incorrect baheviour 13:14
the index < 0 handling is *sooo* Perl 5
and it causes quite a lot of overhead on the HLL side :-(
slowing down *all* indexed accesses 13:15
lizmat goes off adding checks in the settinng
13:31 cognominal joined 13:32 p6bannerbot sets mode: +v cognominal
timotimo do we actually use those semantics anywhere at all? 13:36
should i try to add an exception to moarvm's code and run a spectest to see?
lizmat timotimo: that sounds like an excellent idea :-) 13:37
timotimo building it now 13:39
MVMArray: Index out of bounds 13:40
at gen/moar/stage2/QRegex.nqp:1569 (src/vm/moar/stage0/QRegex.moarvm:!cursor_push_cstack)
should be able to fix code as it comes up, though, right?
lizmat think so... 13:41
timotimo will need a rebootstrap, though
OK, looks like we do actually generate access to negative indices in regex code 13:46
lizmat I guess another legacy from the Parrot days :-( 13:47
timotimo: if you could generate a gist of places where that is happening, I could have a go at it as well 13:48
timotimo i should be able, actually 13:49
i now have a cat on my lap 13:51

here's a compressed text file, it's about 500 megabytes, but i didn't deduplicate at all yet

oh
720 megabytes
uncompressed, that is
compressed it's only 400 kilobytes 14:03
jnthn Yeah, the regex engine will doubtless have been taking advantage of that to get smaller code :)
Not everything will win.
timotimo add an op that does the calculation itself :) :) 14:04

lizmat hmmm... macOS doesn't know about .lzma : ( 14:06

Add negative offset checks to read-int/write-int

To at least make sure we don't release a version of these that do allow negative offsets.		 14:09
lizmat I'm looking forward to be able to revert that one ^^^ 14:10
timotimo hack.p6c.org/~timo/nqp_all_usages_o...es.txt.bz2 - not finished compressing yet
hum. bzip2 isn't extremely fast, that's for sure 14:12
lizmat it's asymmetrical, I seem to recall, yeah 14:13
timotimo so is 7za, at least when i used -9 :)
why did i use -9 for bzip2 as well?
done! 14:14
1.4 megabytes, wow
lizmat 404 on that link ? 14:16
timotimo oh? 14:20
