Test two objects for inequality.
Test two objects for inequality.

Equivalent to x.hashCode except for boxed numeric types and null.
Equivalent to x.hashCode except for boxed numeric types and null.
For numerics, it returns a hash value which is consistent
with value equality: if two value type instances compare
as true, then ## will produce the same hash value for each
of them.
For null returns a hashcode where null.hashCode throws a
NullPointerException.

The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).
The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).
true if the receiver object is equivalent to the argument; false otherwise.
Cast the receiver object to be of type T0.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics.
Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at
runtime, while the expression List(1).asInstanceOf[List[String]] will not.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the requested type.

This is a hack to work around SI-9111.
This is a hack to work around SI-9111. The completer of methodSym may report type errors. We
cannot change the typer context of the completer at this point and make it silent: the context
captured when creating the completer in the namer. However, we can temporarily replace
global.reporter (it's a var) to store errors.
True for classes generated by the Scala compiler that are considered top-level in terms of the InnerClass / EnclosingMethod classfile attributes.

Cache the value of delambdafy == "inline" for each run.
Cache the value of delambdafy == "inline" for each run. We need to query this value many times, so caching makes sense.
Data for emitting an EnclosingMethod attribute.
Data for emitting an EnclosingMethod attribute. None if classSym is a member class (not
an anonymous or local class). See doc in BTypes.
The class is parametrized by two functions to obtain a bytecode class descriptor for a class symbol, and to obtain a method signature descriptor fro a method symbol. These function depend on the implementation of GenASM / GenBCode, so they need to be passed in.
Tests whether the argument (that) is a reference to the receiver object (this).
Tests whether the argument (that) is a reference to the receiver object (this).
The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.x of type AnyRef, x.eq(null) and null.eq(x) returns false.null.eq(null) returns true. When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

True if classSym is an anonymous class or a local class.
True if classSym is an anonymous class or a local class. I.e., false if classSym is a
member class. This method is used to decide if we should emit an EnclosingMethod attribute.
It is also used to decide whether the "owner" field in the InnerClass attribute should be
null.
Test whether the dynamic type of the receiver object is T0.
Test whether the dynamic type of the receiver object is T0.
Note that the result of the test is modulo Scala's erasure semantics.
Therefore the expression 1.isInstanceOf[String] will return false, while the
expression List(1).isInstanceOf[List[String]] will return true.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the specified type.
true if the receiver object is an instance of erasure of type T0; false otherwise.
This is basically a re-implementation of sym.isStaticOwner, but using the originalOwner chain.
This is basically a re-implementation of sym.isStaticOwner, but using the originalOwner chain.
The problem is that we are interested in a source-level property. Various phases changed the
symbol's properties in the meantime, mostly lambdalift modified (destructively) the owner.
Therefore, sym.isStatic is not what we want. For example, in
object T { def f { object U } }
the owner of U is T, so UModuleClass.isStatic is true. Phase travel does not help here.
Reconstruct the classfile flags from a Java defined class symbol.
Reconstruct the classfile flags from a Java defined class symbol.
The implementation of this method is slightly different that javaFlags in BTypesFromSymbols.
The javaFlags method is primarily used to map Scala symbol flags to sensible classfile flags
that are used in the generated classfiles. For example, all classes emitted by the Scala
compiler have ACC_PUBLIC.
When building a ClassBType from a Java class symbol, the flags in the type's info have
to correspond exactly to the flags in the classfile. For example, if the class is package
protected (i.e., it doesn't have the ACC_PUBLIC flag), this needs to be reflected in the
ClassBType. For example, the inliner needs the correct flags for access checks.
Class flags are listed here: https://docs.oracle.com/javase/specs/jvms/se7/html/jvms-4.html#jvms-4.1-200-E.1
The member classes of a class symbol.
The member classes of a class symbol. Note that the result of this method depends on the current phase, for example, after lambdalift, all local classes become member of the enclosing class.
Impl classes are always considered top-level, see comment in BTypes.

Creates a String representation of this object.
Creates a String representation of this object. The default representation is platform dependent. On the java platform it is the concatenation of the class name, "@", and the object's hashcode in hexadecimal.

This trait contains code shared between GenBCode and GenASM that depends on types defined in the compiler cake (Global).
