    • primitiveTypeFromOpcode

      public static Type primitiveTypeFromOpcode(int op)
      Returns the primitive result type implied by a bytecode opcode, or UnknownType when the opcode does not carry type information (e.g. ALOAD, AALOAD, ASTORE).

      Covers:

      • var insns: ILOAD/ISTORE → int, LLOAD/LSTORE → long, FLOAD/FSTORE → float, DLOAD/DSTORE → double
      • arithmetic + negate (IADD–DNEG, opcodes 96–119): I/L/F/D in groups-of-4
      • shift + bitwise (ISHL–LXOR, opcodes 120–131): even → int, odd → long
      • comparison results (LCMP, FCMPL/G, DCMPL/G) → int
      • ARRAYLENGTH → int
      • primitive array loads: IALOAD → int, LALOAD → long, FALOAD → float, DALOAD → double, BALOAD → byte, CALOAD → char, SALOAD → short
