Entire Cortex A-series should work fine with unaligned memory access to RAM when MMU is enabled(which is always on for linux). With few exceptions, but nextcloud is not a device driver.
I never said that.
It was implied in the discussion: "if you can compile it, it will work".
There's plenty of ARM processors before Cortex. There's SPARC. And there's a crapton of others with their quirks.
Just because you can compile a program from source, it doesn't guarantee it will work. As mentioned: online assembly, memory alignment, but you can add endianness or questionable pointer arithmetic, not to mention dynamic runtime code generation. And I'm sure there's 5 other reasons that I haven't personally run into.
Yeah, in a perfect world everyone would write bug-free, platform-independent code, alas...
Nope. If you can compile for this microarchitecture, it will work on it. You know what was implied, I know what was implied, but you choose to run in circles and yell "Look! This person doesn't know that program compiled for one architecture can't run on another!"
Me: says about -mcpu=native
You: oh, yeah, there is completely another architecture.
Ooorr...
Did you just said that SPARC is ARM processor? Who tf are you?
What now?
. . .
What distro runs ARM in big endian? Name one. I think you are just trying to throw as much arguments you don't understand as possible. EOF.
I assume you program in Javascript and haven't written C code ever. SPARC doesn't allow unaligned memory access to this day, no matter what parameters you throw to the compiler. If a program doesn't process endianness won't work correctly. s/online/inline/g. You didn't even address 4 other arguments.
"if you can compile it, it will work" is just false.
Show me your github profile
My github profile is under my real name, so no thanks. Won't be giving my social security or credit card numbers either.
