Directly execute code?

[nikitaosx]

OK, I figured out the Cosmos Forms and made one, but I have a new question: How do I make the CPU directly execute instructions from a file? Like I would parse instructions from an ELF file and execute them directly on the CPU! And also how to implement syscalls so "printf" would run "Console.Write"?

using System;
using System.Runtime.InteropServices;

// Define the signature of the native code entry point
public delegate void NativeEntryPoint();

public unsafe static void ExecuteElf(byte[] elfFileBytes)
{
// Minimal ELF verification (checking the magic number: 0x7F 'E' 'L' 'F')
if (elfFileBytes[0] != 0x7F || elfFileBytes[1] != 0x45 ||
elfFileBytes[2] != 0x4C || elfFileBytes[3] != 0x46)
{
Console.WriteLine("Not a valid ELF file!");
return;
}

/* 
 * In a full ELF loader, you would parse the Program Headers (PT_LOAD segments),
 * allocate memory at the preferred virtual address, and copy the sections.
 * For a simplified bare-metal Cosmos loader, we extract the raw text instructions.
 */
 
// Pin the byte array to get its raw physical address in RAM
fixed (byte* codePtr = &elfFileBytes[0])
{
    // For a flat binary (or if you know the offset of .text inside your ELF, e.g. 0x1000)
    IntPtr addressToExecute = (IntPtr)codePtr; 

    // Cast the raw RAM address into our execution delegate
    NativeEntryPoint runCode = Marshal.GetDelegateForFunctionPointer<NativeEntryPoint>(addressToExecute);
    
    Console.WriteLine("Jumping to machine code execution...");
    
    // The CPU jumps execution directly to the RAM buffer!
    runCode(); 
    
    Console.WriteLine("Returned safely to Cosmos.");
}

}

OK, I'll test this! If it works, I will mark this as the answer!
