The assembly code that the compiler for my programming language produces, and can be assembled using GNU Assembler, works on 32-bit Linux and 32-bit FreeBSD, however, it crashes on Haiku. I do not know what I am doing wrong.
I don’t know FlatAssembly, but the everyday assembly is not platform independent language.
Sure, but if something works on Linux and FreeBSD on x86, you would kind-of-expect it to work on Haiku? Or, rather, as in the case of Windows and DOS, fail to assemble and link, rather than compile without warnings and then crash.
