asciilifeform feels in too shape when gets to walk 4+h. but only on sunday, can..
asciilifeform: the mechanics , imho, well-documented.
asciilifeform: actual degree / coupla added 0s on pay -- also dun change anyffin. in practice.
asciilifeform: re 'career' << i have yet to meet, in usaschwitz, anyone in own gener. with 'career'(tm). unless slow path into bottle and to the bottom can also be called 'career'☟︎
asciilifeform: depressing, 4 of 8 dead, 5th in bear trap...
asciilifeform: fwiw i suspect could be fit in item of roughly similar mass to 'm'
asciilifeform: but the algo per se may be necessary, i.e. gluing of coad in realtime
asciilifeform: mips, for all its schoolbook popularity, has whole buncha non-orthogonal instrs (e.g. movz/movn, beq/bne, etc. pairs, where only diff is negation; all the signed/unsigned pairs, wtf, if you want signed arithm, let compiler do the fucking sign extension ; and all the unaligned byte-addressing ops, fuck'em, let'em address on whole words like bolix, and suck it up, and bonus , lose 'endianism')
asciilifeform: prolly would've added up to less sweat, too.
asciilifeform: then would actually add up to something usable.
asciilifeform: mp_en_viaje et al : thinking re 'bigpicture' -- i suspect that my approach was ill-conceived from beginning. instead of a mips-iii, if doing such thing -- oughta have implemented a radically simplified item with dozen or so instructions; for which could then bake 'fittable in head' bellardistic dynamic emu. and then retarget gcc to it.☟︎
asciilifeform: mp_en_viaje et al : lulzily, if there existed a cycle-accurate emulator of ~pc~ , accurate profiling would be trivial -- simply allocate a word for each instr., and increment that word when the instr executes
asciilifeform: trinque: are you having a 'dulap-I'-style problem ??
asciilifeform: holyfuq, ~6~ mp_en_viaje pieces in absence of deedbot..☟︎
asciilifeform: lol i thought it was all same b&w on mp_en_viaje's 'lynx'
asciilifeform: ^ seems to correspond to the following cut : ~15% time in type-i instrs.; ~4.35% in r-type; 25.5% in memory read/write (incl. tlbisms) ; but the rest, doesn't say...
asciilifeform: ^ corresponds to approx 10min of runtime
asciilifeform: ave1: my 486 also 'ran just fine' lol
asciilifeform: not as gloriously pedantic as ada's docs, but similar in flavour.
asciilifeform: ... and yes there is actually a standard. even sold as dead tree b00k, called 'see mips run'☟︎
asciilifeform: ( likbez for n00bz : mips 'exception handlers' have 0 to do with what normally goes by this name, it is what the mips standard calls what normal people refer to as interrupts & traps )
asciilifeform: ( (a) -- in 'M', (b) -- on the host iron )
asciilifeform: anyone who has a spare 5min, invited to post output of 'time dhrystone 10000000' along with on what iron etc.
asciilifeform: unless someone reads the thing and finds some major optimization that i missed, thing is really at the point of severely diminishing returns, plain old 'cycle massage' won't get much.
asciilifeform: originally i expected a 50+% speedup, but the cache mechanism itself eats cycles.
asciilifeform: ( cache lives in xmm regs, so as to avoid accessing ram. and they're mostly used up, there's 3 left unused )
asciilifeform: theoretically possible that a multi-entry tlb cache would speed up. but not knowable apriori, cuz searching multiple entries also costs.
asciilifeform: also includes fastpath exception handlers (i.e. instead of the conditional tree from genesis ver) and a 'cheat' for tlbwr ('tlb write random') instruction so that it puts recently-created tlb entries near the base of the table, where reached faster while searching.
asciilifeform: ( spoiler : read+write tlb caching nao gives 'pentium 166' both in userland and kernel, instead of 'pentium 166' in kernel and '486' in user. but still ugh. )
asciilifeform: possibly i'm thick, but how does this work ? from surface , loox like thing where e.g. esr puts acct and then gets 'donation button' for his www, and idjits push, etc
asciilifeform: effective begging, as i understand, is a whoring/performance art, like street singing, takes dedication an' energy
asciilifeform not , admittedly, master beggar, perhaps not qual'd to discuss. had even 'paypal' beggatron on www, in '07 or sumsuch, netted not 1 cent. then later replaced with btc addr, and one time someone sent entire coin ! and to this day occasionally nanobtc etc
