  The BTypes component defines The BType class hierarchy.

  The BTypes component defines The BType class hierarchy. A BType stores all type information that is required after building the ASM nodes. This includes optimizations, generation of InnerClass attributes and generation of stack map frames.

  The representation is immutable and independent of the compiler data structures, hence it can be queried by concurrent threads.

35.  final def maxValueType(other: BType): BType

    The upper bound of two primitive types.

    The upper bound of two primitive types. The `other` type has to be either a primitive type or Nothing.

    The maxValueType of (Char, Byte) and of (Char, Short) is Int, to encompass the negative values of Byte and Short. See ticket #2087.

    The asm.Type corresponding to this BType.

    Note about asm.Type.getObjectType (*): For class types, the method expects the internal name, i.e. without the surrounding 'L' and ';'. For array types on the other hand, the method expects a full descriptor, for example "[Ljava/lang/String;".

    See method asm.Type.getType that creates a asm.Type from a type descriptor

    - for an OBJECT type, the 'L' and ';' are not part of the range of the created Type
    - for an ARRAY type, the full descriptor is part of the range

    Some JVM opcodes have typed variants. This method returns the correct opcode according to the type.

    opcode

      A JVM instruction opcode. This opcode must be one of ILOAD, ISTORE, IALOAD, IASTORE, IADD, ISUB, IMUL, IDIV, IREM, INEG, ISHL, ISHR, IUSHR, IAND, IOR IXOR and IRETURN.

    returns

      The opcode adapted to this java type. For example, if this type is `float` and `opcode` is `IRETURN`, this method returns `FRETURN`.
