Converts expressions to Intermediate Representation (IR) for the backend.

Members

addressElem elem* addressElem(elem* e, Type t, bool alwaysCopy): Take address of an elem. Accounts for e being an rvalue by assigning the rvalue to a temp.
clearStringTab void clearStringTab(): Reset stringTab[] between object files being emitted, because the symbols are local.
elAssign elem* elAssign(elem* e1, elem* e2, Type t, type* tx): Generate a copy from e2 to e1.
toElem elem* toElem(Expression e, IRState irs): Convert Expression to backend elem.
toElemDtor elem* toElemDtor(Expression e, IRState irs): Convert Expression to elem, then append destructors for any temporaries created in elem.
toStringSymbol Symbol* toStringSymbol(const(char)* str, size_t len, size_t sz): Write read-only string to object file, create a local symbol for it. Makes a copy of str's contents, does not keep a reference to it.
toStringSymbol Symbol* toStringSymbol(StringExp se): Turn StringExp into Symbol.
toTraceGC void toTraceGC(IRState irs, elem* e, Loc loc): Replace call to GC allocator with call to tracing GC allocator.
type_zeroCopy bool type_zeroCopy(type* t): Determine if zero bits need to be copied for this backend type
