<charliesome> _ko1: i have a proof of concept implementation of immediate single char string values: https://gist.github.com/charliesome/6806385
<charliesome> it means String#[] is now zero-allocation in most cases
<_ko1> ah
<_ko1> mm
<charliesome> it's proof of concept only, and assumes a little endian machine
<charliesome> but I think the idea is worth discussing
<_ko1> i think it should'nt be special value
<charliesome> bit layout: …. 0000 0000 cccc cccc 0001 1110
<_ko1> should be pre-allocated RVALUE
<charliesome> _ko1: oh good idea!
<_ko1> ?x -> frozen, right?
<charliesome> no, that is still equivalent to "x"
<charliesome> this patch only changes String#[] to return an immediate string if possible
<_ko1> only return value of String#[] ?
<charliesome> but I prefer the preallocated RVALUE idea
<_ko1> i'm not sure how it helps
<_ko1> because i don't use String#[Integer] !!
DanKnox is now known as DanKnox_away
<_ko1> One more news, related to this idea.
<_ko1> I will make eden space, which is pre-tenured space.
<_ko1> maybe frozen strings are located at there.
<charliesome> _ko1: what do you mean by pre-tenured?
<_ko1> sorry, pre-tenure is not main topic
<_ko1> mmm, complex to explain
<_ko1> eden is object space which is sweeped only at full GC
<_ko1> shortly, if we can assume that this object lives long, then we can put it on eden
<_ko1> and these objects don't affect GC's speed
<_ko1> especially for sweeping
<_ko1> RGenGC only boost marking phase, not sweeping phase
<_ko1> this technique boost also sweeping
<_ko1> pre-tenure is a technique that predicting long-lived object and tenure (make oldgen object) at first
