jnthn .tell lizmat It depends. If you have a type constraint and that type is *not* Iterable then it generates code that strips off the Scalar container and stores it uncontainerized. That means nothing later on has to decont it again. Plus code-gen improved of late to emit just one decont, not multiple, in this case. 11:29
yoleaux jnthn: I'll pass your message to lizmat.
jnthn .tell lizmat If the parameter is unconstrained on type then \foo is probably faster because it won't defensively created a readonly Scalar wrapper to make sure itemization is retained. 11:31

Remove obsolete p6settypes extop

Since the scalar refactor we don't actually need Mu and Any anymore in extops. All that remained in p6settypes was the initialization of some static strings which can easily be done in p6init.		 14:46

Replace p6decodelocaltime extop with a native call

Usage of the extop pre-dates NativeCall. It was only called in a single place and only once, so it's not performance sensitive.		 14:48

MasterDuke if i have `- QAST::Want <wanted> 10 - QAST::WVal(Int) - Ii - QAST::IVal(10) 10`, and i want to make sure i have a literal int, which thing(s) should i check against? 20:48
20:48 felco8 left
timotimo check if the second child is an "Ii", i guess 20:49
MasterDuke easy enough. how about if i have ($opname eq '&infix:<+>' || $opname eq '&infix:<->' || $opname eq '&infix:<*>'), any easy way to build the right QAST::Op using the $opname? i.e., i want add_i, sub_i, and mul_i respectively 20:54
timotimo not that i know of. also, don't forget to check if they come from the setting 20:57
MasterDuke yeah, i have that already 20:58
timotimo i mean in theory you could use optimize_op for that i guess? that might constant-fold it for you
MasterDuke guess i'll just build a little hash
timotimo i mean you could perhaps have it like $opname eq '&infix:<+>' && $opop := "add_i" || ... 20:59

MasterDuke timotimo: do i need to worry if e.g., the range values + the offset get into bigint territory? 21:29
timotimo hm, i think so? 21:36
does the current optimization stop outside of big int range?
MasterDuke it doesn't look like there are any checks 21:37
timotimo perhaps you can make your new code work completely before the other code does anything
also, if you're in bigint territory, you can't create an QAST::IVal from it 21:38
MasterDuke github.com/rakudo/rakudo/blob/mast...1112-L1126
jnthn I vaguely recall that it looked for a QAST::Want and took the int part of that, the existence of which'd imply it's in range and not need the check 21:39
But it may have change some and/or I may misremember :)
MasterDuke github.com/rakudo/rakudo/blob/mast...2239-L2307

timotimo can you use that mac os equivalent of strace on that? 23:55
is it dtrace?
ok, dtruss seems to give you what you need, but it might have bo se set suid root to work?
lizmat dtrace: failed to execute perl6: dtrace cannot control executables signed with restricted entitlements 23:57
timotimo uhh? 23:58
perhaps you have to cat (which perl6) and put dtruss in front of the commandline there?
lizmat this is quickly becoming too complicated for me at this late hour on a whiskey tasting filled day 23:59
