arnecompiler

A hobby project to create a compiler that compiles my own simple language to x86 asm code. It is powerful enough to solve the first 10 problems on http://projecteuler.net. The language has no built-ins, all basic types like even int, are defined in the language proper.

C libraries can easily be called.

Language example:

include(void)
include(int)
include(memory)
include(io)

variable(pointer array, malloc(_mull(4, 1000)))

function(void set_array, block(variable(int index), variable(int value)), block(
  setmem(_addl(array, _mull(4, index)), value)
))

function(int get_array, block(variable(int index)), block(
  getmem(_addl(array, _mull(4, index)))
))

variable(int chr_a, 48)
variable(int digit, read())
variable(int i, 0)

while(_neql(digit, sub(eof, chr_a)), block(
  set_array(i, digit)
  _incl(i)
  print_int(digit)
  digit(read)
))

variable(int answer, 0)

for(variable(int i, 0), _lessl(i, 995), _incl(i), block(
  variable(int product, 1)
  for(variable(int j, 0), _lessl(j, 5), _incl(j), block(
    product(_mull(product, get_array(_addl(i, j))))
  ))
  if(_greaterl(product, answer)
    answer(product)
  )
))

print_int(answer)

function(int, read, block(), block(
  sub(fgetc(system_stdin()), chr_a)
))
