04:43:04 <tangentstorm> okay, i have a plan for retro <-> pascal communication:  https://github.com/sabren/b4/blob/master/ref/retro-pascal.org
04:46:00 <tangentstorm> also... not sure i actually showed this to you guys or not yet, but a faster js terminal with direct input ( still slightly buggy ) is here : http://games.tangentcode.com/retro/src/console.html

13:49:31 <Mat2> hello !
13:49:58 <tangentstorm> hey Mat2 :)
13:50:12 <Mat2> hi tangentstorm !
13:50:31 <tangentstorm> how are things? i'm compiling :)
13:50:39 <Mat2> nice :)
13:51:42 <Mat2> I'm down from 4.0 s for an empty loop ($10000000 times) to 0.8 s and found that the limit for interpretation
13:52:10 <tangentstorm> !! very nice
13:53:33 <Mat2> because my interpreter recompiles to direct threading code on the fly I'm now on implementing a JIT compiler instead as this is not much mor effort
13:54:01 <Mat2> this way I can use nasm and forget about the frustating limitations (and bugs) of the inline assembler
13:54:14 <Mat2> so the whole compiler will be an external procedure
13:55:52 <tangentstorm> that's handy
13:56:33 <Mat2> I've figured out calls with 64 bit adresses are executed with a latency of 18 clock cycles !!!, this is impressive bad
13:57:40 <tangentstorm> weak. but you probably don't need anywhere near that amount of address space, do you?
13:58:12 <tangentstorm> i've kind of been thinking about switching to 16-bit 
13:58:31 <Mat2> the inline compiler have this limitation (beside restrictions on relative adress generation)
13:59:15 <Mat2> but with nasm I can generate 23 bit address references and these are much more efficient
13:59:25 <Mat2> sorry mean 32 bit of course
14:00:16 <Mat2> are the compiler sources in your repro ?
14:00:19 <tangentstorm> I was talking to a guy who made another pascal "os" that wasn't on that page i showed you
14:00:44 <tangentstorm> all this one does is boot up and say "hello world"
14:00:54 <tangentstorm> not yet
14:01:11 <tangentstorm> https://github.com/sabren/b4/blob/master/ref/retro-pascal.org
14:01:34 <tangentstorm> these are my notes for how i'm planning to do the calling conventions
14:01:56 <tangentstorm> https://github.com/tangentstorm/PL0-Language-Tools/blob/master/pl0_to_retro.py
14:02:18 <tangentstorm> that's the core of the compiler, but no code is generated yet
14:02:45 <tangentstorm> it's based on a python adaptation of niklaus wirth's 450 line pl/0 compiler from 1975 :)
14:03:02 <tangentstorm> ( which is in the same directory there )
14:03:34 <Mat2> ah thats the explanation for my dejá vue
14:03:48 <tangentstorm> https://github.com/nickelsworth/paskernel  <- the "hello world" OS with freepascal
14:04:48 <tangentstorm> the guy that made this is also the author of PTCpas, the SDL alternative for direct graphics
14:05:43 <tangentstorm> ( which also has a text console implementation like what you made for sdl )
14:05:49 <Mat2> ahm, the os kernel interface is very unixoid
14:07:00 <tangentstorm> yeah. he basically made an ELF file so it would boot with GRUB
14:08:13 <Mat2> somewhere I have seen an microkernel in pascal
14:08:28 <Mat2> very interesting sources (and very readable)
14:08:38 <tangentstorm> http://wiki.osdev.org/Pascal_Bare_Bones
14:11:15 <Mat2> who knows, some day there will be an tablet os written in pascal on top of a MISC style vm
14:11:42 <tangentstorm> :)
14:12:14 <tangentstorm> i would love to see that
14:12:44 <tangentstorm> this all came up because there's a guy hanging out in #fpc who's also wanting to make a tiny os
14:13:10 <Mat2> always good to progess from inspiration :)
14:13:11 <tangentstorm> one of the core compiler devs showed up today after reading through the irc logs
14:13:38 <Mat2> in the pascal channel ?
14:14:12 <tangentstorm> yeah. he was explaining to that guy that you can use "embedded" as the target OS
14:14:36 <tangentstorm> if you are doing stuff like wanting to make your own operating system. the runtime library gets much smaller that way
14:14:53 <Mat2> good to know
14:17:17 <tangentstorm> logs are http://www.elesoft.net/lift/lift.php?prefs[showtype]=current&prefs[channel]=100 he explained it much better than i did
14:17:50 <tangentstorm> under todays chat i guess
14:24:01 <Mat2> very interesting read
14:33:59 <Mat2> look here:
14:34:03 <Mat2> http://j-software.dk/rtos.php
14:34:46 <Mat2> http://j-software.dk/os.php
14:34:49 <tangentstorm> huh!
14:34:53 <tangentstorm> hadn't seen that one
14:35:38 <tangentstorm> also http://j-software.dk/os.php
14:35:43 <tangentstorm> oh :)
14:42:30 <Mat2> nice handy os
14:42:46 <Mat2> (and written in pascal)
14:43:52 <tangentstorm> just added it to the fpc wiki
14:49:28 <Mat2> need some sleep, I will upload my current sources tomorrow night as I want to finish the JIT vm
14:49:45 <Mat2> I think it matures enough to be usable
14:50:59 <Mat2> (beside some minor bugs for sure)
14:51:30 <Mat2> is mature the right word ?? hmm, anyway
14:51:34 <Mat2> ciao
