Pre-task for language team
main.c is a partial implementation of a small VM capable of performing simple
arithmetic. To finish the implementation, fill out the blanks labeled with
TODO. We have given a correct implementation of ADD as an example for you,
and a few macros for interacting with the VM you may find useful (PUSH and
POP). More complete instructions can be found in the file.
some example programs: Either DCONST, 0x3F, 0xF0, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, PRINT, HALT or DCONST, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xF0, 0x3F, PRINT, HALT should print 1.0. Which one will work on your machine depends on
your implementation of DCONST and/or the endianness of your machine.
DCONST_2, ST1, DCONST_M1, LD1, DIV, PRINT, HALT should print -0.5.
To build the program, you run the make command make. By default, the fibonacci
program is loaded, and will run on program execution (./arithmatic_machine).
To use other programs, modify main.c:269 to use other arrays.
If you feel like this was too easy, feel free to add any capabilities you want to the VM.
