Re: LLVM news?

@MigthyMax

The point I was trying to make was that Rust is a fast-moving target and won't stay up-to-date very long.

@MigthyMax
It looks like your Reddit link is about right. It's also about 5 years old.

Re:Rust
I have been using Rust on Haiku for a while now and the syntax highlights are all the editors there have to offer. Tier 3 support means no cross compiler hosting for other platforms to use. The source is hosted on GitHub like any other source and the build recipe on HaikuPorts builds a native Haiku compiler for the HaikuDepot package manager using Haiku's own continuous integration expenses. Fortunately, Haiku Inc. is a non-profit corporation so the CI build bots are probably donated.

If the same thing were done for AmigaOS 4.1fe2, who would maintain the build bots and at whose expense? Neither AEon nor Hyperion are non-profit groups.

I always hoped that someone could write a custom pass manager that would allow each pass of the optimizer to be stored in a separate shared library so they could load in a few at a time and close the unused ones so they could be flushed out of RAM on an Amiga.

I was naieve enough at one point to think that someone would be me. Heh! Weren't those the days!

Although I'm going the other direction, from Amiga to Haiku, I'm glad you've come to terms with being an Amigan. My MicroA1 is bordering on unusable with the latest version of AmigaOS 4.1 and it's hard to get excited about a 15 year old Mac Mini running MorphOS, but I find scripting in Hollywood tolerable in MorphOS and Linux.

Re: Idea of the day - FPGA Amiga on a PCI card (or even a USB stick)

I was hoping to get a cut down version of the PicoEVB for my PineBook Pro and run it under Linux with a MiniMig core variant with the video and audio rendered as memory-mapped I/O to the host hardware. Of course the DevBoard I've linked is way more complicated than it needs to be and it costs $200+ to reflect that. The rest of the chipset emulation can run on one of the little cores on the RockChip RK3399 while one of the big cores can run the actual JIT code.

This chip would be well suited to running on a PCI or PCIe board also. It runs fanless and has enough space for future expansions such as SAGA chipset emulation like the Vampire standalone. I'm not sure how much the FPGA chip costs by itself though.

Amiga name rights

I heard on Amiga Addict magazine's Discord server that AmigaKit is voicing objections to the Amiga Addict trademark application. Others have voiced instances where AmigaKit had beaten A1200.net to the trademark office and misrepresented their A1200 cases as their own product. Anither lawsuit is brewing there too.

Where will this all end?

I suggested using an augmented MiniMig core as an alternative to modern graphics drivers. It was a possibility that couldn't be made modern because of massive incompatibility between floating-point based 3d acceleration and integer-based Amiga chipset modes.

On another occasion I tried to create a translation layer that would use shaders on modern graphics chips to implement copper-style tricks. It could emulate a palette with copper shading in theory but nothing more. Most modern chipsets aren't designed for palette modes anyway.

Perhaps a hybrid solution could exist: a Minimig core that could output to a texture map so a modern card could display the emulation in a window.

Re: What's the status of the C++ runtimes

Since all the named labels are behind a string hash lookup to translate to the numbers, your example might already work. Computed Goto and Gosub commands might take some more doing because they are numbered but nothing a second hash can't provide. The functions-in-the-data-statements are indeed tricky. I might need to link to a second C++ file to implement that coroutine. This is my second attempt at compiling AmosPro as portable code. The first failed attempt was codenamed Mattathias.

To describe the compilation strategy see this Yab2Cpp wiki entry.

@Kamelito

YAB stands for "Yet Another BASIC". It is the BASIC interpreter used by the Haiku operating system as a hand-me-down from the later days of BeOS. It's fully open-source and exists for making GUI based applications much easier to write.

@LiveForIt

It uses the same algorithm as Mequa was going to use on XAmos before he died. I plan on making it work with AmiDark's AmosPro Unity libraries sometime after Yab but would like to share some code with your Amos Kittens project as well on AmigaOS 4 if you are willing.

In the meantime I'll be focusing on making Yab compile using C++11 as a backend. Maybe if I can find some help I might get an Amiga Yab working as well. (The interpreter is partially translated to Windows, Mac and Linux using FLTK as an API.)

@Capehill

Thanks for looking into it. Not having to backport completely down to C99 helps a lot.

I'm writing a BASIC to C++ exporter/transpiler in C++11. I need to know if I can use it on AmigaOS after I'm done with the Haiku native version: It's called Yab2Cpp.

Thanks Raziel. I would have had to figure out a way to split endians along the lines of a sandbox if I tried to do it on AmigaOS 4.1FE anyway.

GCC 10 and LibStdC++ can do it if it's up to date. The LLVM equivalent to LibStdC++ is LibC++ and it's as much of a pain to port as LibStdC++.

Rust uses LLVM as a backend and optimizer. It doesn't specifically use GLibC unless you are using the Linux backend. It does need to be able to compile LLVM in C++20 or so.

OS4 shared object format: like Linux?
Just popping in
Just popping in


Hello, I haven't posted here for a while.

I'm kicking around the idea of trying to get Rust to cross compile to OS 4 and then see about getting Wasmer to run on it. One dependency that seems to be hard to avoid is that the WASI ABI for Wasmer uses shared objects in a POSIX-style format. If there is a query capable symbol exporter for an OS 4 shared library, that might be another option.

Another hard-to-avoid dependency is that the Wasmer sandbox environment is strictly little-endian. This means that anything accessible outside of the sandbox will need to be endian swapped to interface to the OS.

That said, I haven't learned to program in Rust yet so don't get your hopes up of having a glut of software written for Wasmer at this time.

@LiveForIt

I notice you're using the OldOpenLibrary LVO. If you're testing on OS 4.x that LVO may no longer be valid. It's been deprecated since the new OpenLibrary superseded it in Kickstart 2 or earlier. Passing a zero as the version number parameter to the OpenLibrary LVO does the same thing and is definitely supported.

I think you need to create a simple_sprite structure. I'm not sure if ext_sprite structures are even supported by the OS 4 pointer.

I know for sure that 16-color pointers aren't supported but that wasn't what you asked.

All those .S files in the source, IIRC, are Assembly source. I'd assume it's designed for the 68k so there's very little chance of being ported to OS 4.
