Exercise 52: A Tiny Virtual Machine – Part 5: Compiler for Bytecode

Goals:

• Create a tiny “assembler” that emits bytecode for your VM.
• Understand how compilers parse and emit instructions.

Topics Covered:

• Create a basic script parser.
• Map mnemonics like LOAD R0, 42 to machine code bytes.
• Write programs like:

asmCopyEditLOAD R0, 5
LOAD R1, 10
ADD R0, R1
OUT R0
HLT

• Output:

bashCopyEdit$ ./vm program.bin
