Can I execute some code(asm -> hex) in the heap memory?
The x86 architecture was successful, but armv8 failed. (tested on Android os)
Is it because the code is not designed to run in the heap area in the ARM cpu?

thanks for reading
test code

usinged char prefix[] = { 0xE0,0x01,0x80,0x42,0xc0,0x03,0x5F,0xD6}; // ARMv8
char *func = (char *)mmap(0, 8, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANON, -1,0);
memcpy (func, prefix, sizeof(prefix));
int result = ((int (*)(void))test_function)();
return result;

x86 prefix

push    ebp
mov     ebp, esp
mov     eax, 15
pop     ebp
ret     0
=> unsigend char prefix[] = { 0x55, 0x89, 0xE5, 0xB8, 0x0F, 0x00, 0x00, 0x00, 0x5D, 0xC2, 0x00, 0x00 };
