AdPlug ARM-iPaq status

[Ildar M. <il...@co...>]

       Hello, everybody,
I have 2 news. One of them is good, another is bad :-)
1. Adplug + Adplay compile and run on ARM platform (I've got iPaq 3970)
2. It's too slow to run acceptable.
Second point confuses me most. I've got scummvm running on the same 
Familiar Linux with adlib emulation sound great. Where's the bottleneck? 
Any ideas?

Thanks! Best regards, Ildar.

Thanks for the information. I will add it to the supported platforms
list. Which version of AdPlug, operating system and compiler did you
use?

This is really confusing. ScummVM's OPL2 emulator is identical to the
one, we're using, so this can't be the issue. And AdPlug's replayers
shouldn't be too processing-intensive, too, at least by far not as much
as ScummVM's gfx-rendering.

Do you got any profiling tools at hand?

Adplug/Adplay are the newest, ver. 1.4.1 / 1.3. OS is Familiar Linux 
ver. 0.7.2 (http://familiar.handhelds.org/). Dev package is from that 
site too, it's arm-linux-gcc version 3.3.2

I know that. That is why so-o-o strange.

Should be.

Not yet. Do you propose to "profile" it? Can you do that for ix86 
version to see that replaying does not eat >50% CPU?

Is WinCE a tested platform? was it allright on it?

Thanks, Simon! BR Ildar

Yes. It may take a while, until i get more time to work on adplug, but
i'm sure i can do some profiling around next month.

> Is WinCE a tested platform? was it allright on it?

As far as i know, AdPlug has never been tested on WinCE.
