$> clang main.c && ./a.outmain.c is a partial implementation of a small VM capable of performing simple arithmetic. To finsih 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.
If you feel like this was too easy, feel free to add any capabilities you want to the VM.
