100% agree your nominations

@joerg

The question is.. you have great skills and deep knowledge of AmigaOS internals, so I wonder why you don't join Andrea and others developers to build an open source alternative to all this mess?

..Waiting for new SDK release, tnx Walkero!

Opensource OS4 newlib could be a solution, at least clib4 could benefit from some OS4 specific code and resolve I/O speed issues and maybe other tips too.

To give a little chance to Amigaos all OS4 code should be opened..

Welcome!

..You could also think about a checkbox for case sensitive search, useful for C code.

Andrea superstar!

@kas1e
It's a very interesting project, I love native software with reaction GUI.
I will follow development in my spare time, keep up the good work!

Great news and congratulations to everyone involved!
I hope the project becomes a reality within the next 12 months. If OS4/MOS is supported, I'm sure I'll be among the first adopters.

Anyway, I still believe that QEMU virtual boards are the best option to ensure Amiga software survives in the future.
They will never break, and year after year they will become faster and more accurate clones of the original hardware.
Thanks to Zoltan, a future version of QEMU will also include support for a virtual Pegasos I board.

@Steffen
you should never leave Amiga scene.. welcomw back!
Your work is really much appreciated.

If you want to see more software for A1222 you need to get full SDK and GCC compiler support.

The best way to run QEMU should be a GUI to configure all options more friendly, just like WinUae does.
It's important to take note of all hardware configurations that lead to right results, just like Hacktintosh experience..

@all
look at also here https://eab.abime.net/showthread.php?t=118993

It would be nice to have a GUI to launch QEMU fully functional and ready for a vifo-pci pass-through, audio and usb fully working.

It would be nice also to identify a laptop and a minipc (macmini?) 100% compatible with QEMU OS4

Very impressive, it will be my next amiga
Keep up the good work!!

It's a great enhancement and it's free for both 460ex and 440ep platforms.
In these days seems an incredible thing..
ACube rocks!

It's up and running fast, thank you!

@walkero

Well done 👍🏻
I'll wait for AK answer if any.

@FlynnTheAvatar

Maybe e5500 does not recognize the instruction opcode simplify because it's not present.
Try with another CPU target just like -mcpu=604e
Some instructions are specific for PowerPC CPU families, other are derived from IBM Power ISA.
In Amigaland we have a to support a mix of CPU with a shared common base ISA and some specific peculiarities that are incompatibile each other.

Tune option is for instruction rescheduling and yess it don't break compatibility but optimize code for superscalar CPU and their caches to run multiple instructions at same time.

@msteed

For X1000 you can go with this

-mcpu=7400 -mtune=7400 -maltivec -mabi=altivec -fomit-frame-pointer -O3

but if your code is executed on different cpus (without Altivec) it will crash.
So you can go with conditional compilation and build binaries for specific models or use runtime dinamic codepath for highly optimized specific code, just like altivec or spe units.

If you want produce a good job you need to go with assembler or lowlevel C code using intrinsics for SIMD.
For SIMD you have to rethink the whole algorithm and for loops go with steps of multiple of 4 (for altivec).
Autovectorization can't do miracles, maybe with modern IA you can ask for a help rearranging code.

I don't know -Ofast GCC switch and need to go inside it further.
