LLVM: llvm::CallLowering::ValueAssigner Struct Reference (original) (raw)
Argument handling is mostly uniform between the four places that make these decisions: function formal arguments, call instruction args, call instruction returns and function returns. More...

|---|---|
| ValueAssigner (bool IsIncoming, CCAssignFn *AssignFn_, CCAssignFn *AssignFnVarArg_=nullptr) | |
| virtual | ~ValueAssigner ()=default |
| bool | isIncomingArgumentHandler () const |
| Returns true if the handler is dealing with incoming arguments, i.e. | |
| virtual bool | assignArg (unsigned ValNo, EVT OrigVT, MVT ValVT, MVT LocVT, CCValAssign::LocInfo LocInfo, const ArgInfo &Info, ISD::ArgFlagsTy Flags, CCState &State) |
| Wrap call to (typically tablegenerated CCAssignFn). | |
| CCAssignFn * | getAssignFn (bool IsVarArg) const |
| Select the appropriate assignment function depending on whether this is a variadic call. |
| Public Attributes | |
|---|---|
| CCAssignFn * | AssignFn |
| Assignment function to use for a general call. | |
| CCAssignFn * | AssignFnVarArg |
| Assignment function to use for a variadic call. | |
| uint64_t | StackSize = 0 |
| The size of the currently allocated portion of the stack. |
Argument handling is mostly uniform between the four places that make these decisions: function formal arguments, call instruction args, call instruction returns and function returns.
However, once a decision has been made on where an argument should go, exactly what happens can vary slightly. This class abstracts the differences.
ValueAssigner should not depend on any specific function state, and only determine the types and locations for arguments.

Returns true if the handler is dealing with incoming arguments, i.e.
those that move values from some physical location to vregs.
