@bison

I do not know how good AmigaOS runs in FS-UAE on Linux but Aros Vision should work quiet well

little bit of marketing

@OlafS25
i need it under linux vr to simplify testing builds, otherwise i constantly need to shove data to windows host. i will try out as soon as it may make sense to go forth with aros68k, currently the bug in the screenmode prefs affecting resolution is putting me off.

@wawa

some time ago I created this page for FS-UAE:
http://www.aros-platform.de/html/fs_uae.html

newest versions (dev builds) are slightly different and have JIT activated (at least the 64bit versions)

"The new x86-64 JIT compiler is available and enabled in the 64-bit versions. "

Thanks for the "stupid" part.

How do you know, that I don't know? Perhaps I know...


Birbo I didn't mean to offend you, so I'm sorry if that was the case. I just thought the last thing we needed to hear was some wild speculations, or something which the usual suspects could call "fanboy dreams" later on.

Speaking of speculations we can only guess what it takes to get Petunia JIT to emulatie 68k FPU on that hardware. Since it was written in PPC asm there could be some interesting obstacles.

@thread

Here some random and largely pointless statistics for you:

I analyzed te programs I used within the last year by processing appdir: with the following script.


#!SDK:Local/C/perl

use strict;
use warnings;

opendir DH, "APPDIR:";
my @exes = readdir DH;
closedir DH;

my $floats = 0;
my $total = 0;

foreach (@exes) {

my $result = `objdump -d \"APPDIR:$_\" | grep \"f1,\"`;
$floats++ if not $result eq "";
print "$_\n" if not $result eq "";
$total ++;
# last if $total > 10;
}

print "Total: $total Floats: $floats\n";




Of the 536 programs in Appdir: (on my SAM-Flex, other machines eother will ofcourse differ) 150 show some sign of floating point code.

Full list below, quite a number of which are clib2 programs from th SDK tools, so the floating point code is likely from stdio compiled with libm, for example can't see 'Kill' using floating point code for real. The test for floatig popint code likely through up a couple of false positives, but unlikely to be any false negatives, unless the code was very minimal.

There were also 154 68k objects in Appdir:

Output: (I moved the final line to the top)


Total: 538 Floats: 150

@broadblues

seems nothing essential in there;)
btw. out of interest, if you compile with clib2 against libm, fp functions get linked statically in no matter if necessary? i thought the usual would be to have only the functions used not the whole lib.

@broadblues

The list is missing shared libraries. Certain audio, image and video codecs are using floats for sure. Of course, they can be recompiled to different CPU target...

68k programs are not affected because they use 68k FPU instructions which are always emulated. Just change the emulator...

I'd have to check to be sure, but I seem to remeber that linking with libm replaces various stdio functions with ones that can handle floats. Those function might draw in a few others, whether or not they are called.

Did you really expect to find machine code by looking for ASCII chars?
Try looking for Hex EC0D0072, C1A30000, EC0D0072, FDA0001E or D9BF0010.

Any C code that use float or double will be using the FPU, that should 80%-90% of all programs.

He used objdump (that creates disassembly output from binaries).

@itix

For example MiniGL, which does all the transformations on the CPU.

@itix

Okay just for fun whilst preparing my meal I switched the root to LIBS: and ran again. No recursion in subdirs though life is too short and that script is suprisingly slow!

Last but not least, Linux (and apps) supports 64-bit (thanks to the 64-bit general purpose registers), so double precision can be supported (with DPESFP) as well.

OS4, instead, runs in 32-bit mode, ...

I know your second posting referred to SPE/DPE-SFP, but I also read several times with regard to making OS4.x 64 Bit that this would require a recompilation of the apps.

And this is exactly what I don't understand.

For example, here at work I have an Dell OptiPlex 2010 with 64 Bit quad core cpu, running 64 Bit version of Win7.
I had absolutely no problems to run Xabier Payet's 'SnapShoter' on it, although 'SnapShoter' is a Hollywood program compiled for Win32.

There was no need to re-compile it for 64 Bit - the 32 Bit version simply worked in the 64 Bit environment.
It is completely beyond me why this should not be possible with 64 Bit AmigaOS4.x and 32 Bit Amiga apps...

Can you explain this to me, please?

In short, the difference is that Windows (and many other o.eses) never publicly exposed its data structures, and used some abstraction mechanism (handles, void pointers, getter & setter) to offer an "opaque" interface to the applications.

This way, it's possible to completely change the implementation without breaking the API, and it's also possible to make a 32-64 bit tunneling, like you reported.

I make another example. Windows 3 introduced the first (sub)version of the famous Win32 APIs, but such APIs are internally "tunneled" (dispatched) to the Win16 implementation. The tunneling provided a conversion mechanism to transparently send the Win32 requests to the Win16 subsystem, converting the parameters (and the return values) back and forth. That happened for all Windows 9x version. On Windows NT, instead, the Win16 requests are tunneled to the Win32 subsystem.
All this was possible due to the abstract interface provided by the o.s. to the application.

Unfortunately the Amiga o.s. hadn't such good design practice, since the used (even private!) data structures were completely published. This means that (usually) it's not possible to exchange (with a tunnel mechanism) data structures between the 32 and the 64-bit subsystems.

Think about a Screen structure which was allocated by (for) a 64-bit application: you cannot pass it to a 32-bit application.

That's the reason why the Amiga o.s. never had the chance to be modernized, since it means rewriting the existing apps.
