And since it’s assembly, I really can’t verify what Gemini is babbling about after I explain the problem, the new function, and the resulting compilation error… :?

To add to the confusion, chatGPT doesn't agree with its counterpart:
There is no sys_cacheflush syscall on ARM64 / AArch64 Linux or Android.
It simply does not exist. On 32-bit ARM, yes, there was __ARM_NR_cacheflush, but on AArch64, the kernel does not expose it, and you cannot invent a syscall number like $0F0002 on AArch64. That number is not meaningful on ARM64. That is why your approach is fundamentally wrong.
Is this true, or is this made up? :lol:

Ok I will try a different approach in the next few days.

Please pull the latest source changes from Github. I've reduced the number of code generation blocks required when making external function calls. This should hopefully make it more stable.

I've only tested compilation for Windows so let me know if there are errors when compiling for Android.

ZExpressions.pas(2344,23) Error: identifier idents no member "Proc"

I believe line 2344 should be:
PDummyFunc(Self.Entry.Proc)^(1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1); //Should never execute

Now it compiles and runs fine. I’m running the thousand-cubes test: no crash. This seems very promising :D
I’ll let it run on two devices while I finish watching a movie, then I’ll try it with my game!

Well done!

I’ve been playing my game for quite a while, with all kinds of semi-transparent lasers and explosions, and in many different situations. Not a single crash.

I can’t express how happy and relieved I am. That was one hell of a bug hunt...

Tomorrow I’ll release the previous version of Omeganaut for Android 64. Then I’ll finally be ready to start feeding the project with lots of content.

For the knowledge, Ville, could you explain what you changed in your last commits? I believe you replaced pointers with something else?
