AIA4

AIA4 is a drastic redesign of the AIA Lang. It reverts back to the simplicity of AIA 1. NOTE Development on AIA4 has ceised since we have joint forces with the JERAN FOUNDATION to work on SIA and the VERA Project, this decision was made by new manangement we decided to move away from our old projects. We sincerely hope that someone can find a use for this!

Source

AIA4 goes back to more assembly like code found in AIA1. Source files are commonly stored as .aia or .aia4. Sometimes it is also stored as .asm, this is not recommended, since it is not a real assembler and could cause confusion. The following is an example of a program counting to 0 to 100.

@lnk_dat "counter.aiad"

log "This is an example program counting up to 100\n"

set $0 0x00 ; counter
set $1 0x01 ; incrementor
set $2 0x65 ; limit

:loop
   log "I: "
   log $0
   log "\n"

   add $0 $1 ; Add the values from addresses $0 and $1 together
   cpr $1 $0 ; Copy the value of the accumulator to address $0

   cmp $0 $2 ; Check the counter against the limit
   jl  _loop ; Jump back to the start of the loop if $0 is smaller than 0x65 (0x4d)

   log "Reached 100!\n"
   stop      ; Stops the program, this is only reached if $0 exceeds 0x64

Compilation

The AIA4 runtime has a built in Compiler. This Compiler does no code-optimization, rather it translates the source 1 to 1 into binary. This compiler is not finished as of right now.

Runtime

The AIA4 runtime is easy to use. To execute a program simply execute the runtime jar. This requires you to put atleast the -f <compiled file> argument. There are also these other arguments:

• -nis | Enable the Netowrk Instruction Set (Not Implemented)
• -ms | Set the amount of bytes usable as memory
• -v | Gives the current version
• -saveState | Save all data of the LangProcessor to a text file.
• -pje | Enables the printing of Java Exceptions in the LangProcessor
• -debug | Enables program debug mode
• -sl | Enables the SystemLogger

Big TODO / WIP Things

• Implement Network Instruction Set
• Finish STDIO Instruction Execution
• Fix Issue with Label Offset in Compiler
