README

        
; Main function of the program, automatically invoked by the VM.

; It must be present in every executable file.

; Valid main functions are main/0, main/1 and main/2.

;

.function: main/0

    ; Allocate local register set.

    ; This is done explicitly by the callee because it is an implementation

    ; detail - if a newer version of the function requires fewer (or more)

    ; registers the code using it should not have to be recompiled.

    ; Also, when a module is reloaded the code using it can stay the same as

    ; long as the number and types of parameters of the function stay the same.

    allocate_registers %4 local

    ; Store text value in local register with index 1.

    ; The text instruction shares operand order with majority of

    ; other instructions:

    ;

    ;     ...

    ;

    text %1 local "Hello World!\n"

    ; Store integer value in local register 2.

    ; Use a 1 because it will be used to represent the standard output stream on

    ; UNIX-like systems.

    integer %2 local 1

    ; Write "Hello World!" on standard output. The io_write instruction will

    ; create an I/O request that will be carried out asynchronously and

    ; immediately return control to the process.

    io_write %3 local %2 local %1 local

    ; Wait for the completion of the I/O request. In this case, the timeout

    ; given is 1 second.

    ; Void register (signified by the use of 'void') is used to tell the

    ; instruction that the result of the I/O operation is not needed and may be

    ; discarded.

    io_wait void %3 local 1s

    ; The finishing sequence of every program running on Viua.

    ;

    ; Register 0 is used to store return value of a function, and

    ; the assembler will enforce that it is set to integer 0 for main

    ; function.
