The following is a sample of assembly code for the Intel 8086 CPU:
The following is a sample program written in assembly for an ARM [[CPU]] running Linux kernel with [[ARM EABI]] system call conventions. The program will print "hello world" to standard output.
<pre>
# Arguments are passed in registers r0-6, the system call number in r7
# Write msglen bytes starting from address msg to standard output (file descriptor 1)
mov r0, #1
adr r1, msg
mov r2, #msglen
mov r7, #4
swi #0
# Exit with status 0
mov r0, #0
mov r7, #1
swi #0
# Assembler macros that specify the data
msg:
.ascii "hello world\n"
msglen = . - msg
</pre>
