Functions

Name	Description
`assignInPlace(dest, src)`	Assignment helper functions
`changeArrayLiteralLength(loc, arrayType, oldval, oldlen, newlen)`	Given array literal oldval of type ArrayLiteralExp or StringExp, of length oldlen, change its length to newlen. If the newlen is longer than oldlen, all new elements will be set to the default initializer for the element type.
`createBlockDuplicatedArrayLiteral(pue, loc, type, elem, dim)`	Helper for NewExp Create an array literal consisting of 'elem' duplicated 'dim' times.
`createBlockDuplicatedStringLiteral(pue, loc, type, value, dim, sz)`	Helper for NewExp Create a string literal consisting of 'value' duplicated 'dim' times.
`ctfeCmp(loc, op, e1, e2)`	Evaluate >,<=, etc. Resolves slices before comparing. Returns 0 or 1
`ctfeEqual(loc, op, e1, e2)`	Evaluate ==, !=. Resolves slices before comparing. Returns 0 or 1
`ctfeIdentity(loc, op, e1, e2)`	Evaluate is, !is. Resolves slices before comparing. Returns 0 or 1
`findFieldIndexByName(sd, v)`	Same as getFieldIndex, but checks for a direct match with the VarDeclaration
`intSignedCmp(op, n1, n2)`	Returns e1 OP e2; where OP is ==, !=, <, >=, etc. Result is 0 or 1
`intUnsignedCmp(op, n1, n2)`	Returns e1 OP e2; where OP is ==, !=, <, >=, etc. Result is 0 or 1
`isCtfeComparable(e)`	Constant folding, with support for CTFE Return true if non-pointer expression e can be compared with >,is, ==, etc, using ctfeCmp, ctfeEqual, ctfeIdentity
`isCtfeValueValid(newval)`	CTFE Sanity Checks
`isPointer(t)`	Pointer operations
`isTypeInfo_Class(type)`	TypeInfo operations
`needToCopyLiteral(expr)`	Aggregate literals (AA/string/array/struct)
`pointToSameMemoryBlock(agg1, agg2)`	Return true if agg1 and agg2 are pointers to the same memory block
`realCmp(op, r1, r2)`	Returns e1 OP e2; where OP is ==, !=, <, >=, etc. Result is 0 or 1
`resolveSlice(e, pue)`	If e is a SliceExp, constant fold it.
`specificCmp(op, rawCmp)`	Returns cmp OP 0; where OP is ==, !=, <, >=, etc. Result is 0 or 1
`voidInitLiteral(t, var)`	Void initialization

Classes

Name	Description
`ClassReferenceExp`	A reference to a class, or an interface. We need this when we point to a base class (we must record what the type is).
`CTFEExp`	This type is only used by the interpreter.
`ThrownExceptionExp`	Fake class which holds the thrown exception. Used for implementing exception handling.
