Talk:Dynamic recompilation

untitled

Is Android's JIT compiler considered dynarec? Their new ART obviously isn't. — Preceding unsigned comment added by Kvswim (talk • contribs) 02:08, 12 December 2013 (UTC)

Merge from Dynarec

In the second paragraph, what the heck is Corn? And second, the example really has little to with Dynamic Recompilation and is closer to High Level Emulation. Dynamic Recompilation stores blocks of recompiled code in memory, so that it doesn't have to decode and simulate instructions everytime.

lda #4
adc ($4), x

would become something like:

mov eax, 4
push eax
push eax
call getX86Addess
mov ebx, eax
pop eax
add ebx, edx
adc eax, [ebx]

and decoding will continue until a branch/jump/call is reached. 24.13.122.71 01:52, 19 June 2006 (UTC)

http://corn.telefonia.pl/ apparently, I've never heard of it either. Feel free to insert a better example, I'm by no means an expert on the subject. StealthFox 11:32, 19 June 2006 (UTC)

I have suggested that Dynarec be merged into this article, as they are two articles on the same thing. Anyone see any reason why not? StealthFox 02:16, 26 December 2005 (UTC)

RISC Generally preferred?

"In an ironic twist in real world usage, the first sequence of instructions (RISC) is generally preferred over the next (CISC). The reasons provided are slow CISC processor execution, prevention of pipeline stalls, and lower hardware overheads."

Preferred where? Code compiled for i386 is chock-full of rep.cmps . Given the platform's performance and market share, surely i386 is representative of the real world?

Example

I don't really get the example. It doesn't explain, why dynamic recompilation is needed. There is absolutely nothing in this example that cannot be recompiled in a static way. --- Krstfrs (talk) 13:37, 10 March 2009 (UTC)

This is true I may write a better/revised one Bostwickenator (talk) 06:21, 15 April 2012 (UTC)

Merge with JIT

Should the article be merged with Just-in-time compilation? Both appear to be describing the same thing. Smk65536 (talk) 06:35, 16 May 2014 (UTC)

Hello there! Well, JIT should be considered as a form of dynamic recompilation, so it would be better to keep these articles separate. Dynamic recompilation is a much broader term as it includes other approaches used in emulators and virtual machines, for example it covers various cross-platform emulations. — Dsimic (talk | contribs) 15:13, 18 May 2014 (UTC)
