  What's New in v5.3.0

  Native Runtime (364 bytes)

  Embedded x86_64 runtime with 7 routines:

  • heap_init — brk-based heap allocator (r14/r15 registers)
  • heap_alloc — bump allocator with 8-byte alignment
  • str_alloc — allocate [length][data] strings on heap
  • str_concat — concatenate two heap strings
  • str_print — write string + newline to stdout
  • str_from_int — convert integer to heap string
  • print_int — direct integer output

  Tagged Values

  • Negative values = string pointers (negated)
  • Non-negative values = integers
  • ADD checks tag: string concat or integer add
  • PRINT checks tag: str_print or print_int

  New Features

  • String concatenation: "Hello" + " World" → 688-byte binary
  • Int-to-string: x.to_s via METHOD_CALL → str_from_int
  • "Answer: " + x.to_s → Answer: 42 in 668-byte binary
  • String length via METHOD_CALL length 0
