assignAddress
protected VariableStorage assignAddress(Program program, DataType tp, int[] status, boolean ishiddenret, boolean isindirect)
Assign next available memory chunk to type- Parameters:
program
- is the Programtp
- type being assigned storagestatus
- status from previous assignmentsishiddenret
- is true if the parameter is a hidden return valueisindirect
- is true if parameter is really a pointer to the real parameter value- Returns:
- Address of assigned memory chunk
-
assignMap
public void assignMap(Program prog, DataType[] proto, java.util.ArrayList<VariableStorage> res, boolean addAutoParams)
Description copied from interface:ParamList
Given a list of datatypes, calculate the storage locations used for passing those datatypes
-
getPotentialRegisterStorage
public VariableStorage[] getPotentialRegisterStorage(Program prog)
Description copied from interface:ParamList
Get a list of all parameter storage locations consisting of a single register- Specified by:
getPotentialRegisterStorage
in interfaceParamList
- Parameters:
prog
- is the controlling program- Returns:
- an array of VariableStorage
-
saveXml
public void saveXml(java.lang.StringBuilder buffer, boolean isInput)
-
restoreXml
public void restoreXml(XmlPullParser parser, CompilerSpec cspec) throws XmlParseException
- Specified by:
restoreXml
in interfaceParamList
- Throws:
XmlParseException
-
getStackParameterAlignment
public int getStackParameterAlignment()
Description copied from interface:ParamList
Return the amount of alignment used for parameters passed on the stack, or -1 if there are no stack params- Specified by:
getStackParameterAlignment
in interfaceParamList
- Returns:
- the alignment
-
getStackParameterOffset
public java.lang.Long getStackParameterOffset()
Description copied from interface:ParamList
Find the boundary offset that separates parameters on the stack from other local variables This is usually the address of the first stack parameter, but if the stack grows positive, this is the first address AFTER the parameters on the stack- Specified by:
getStackParameterOffset
in interfaceParamList
- Returns:
- the boundary offset
-
possibleParamWithSlot
public boolean possibleParamWithSlot(Address loc, int size, ParamList.WithSlotRec res)
Description copied from interface:ParamList

- Parameters:
loc
- is the starting address of the rangesize
- is the size of the range in bytesres
- holds the resulting slot and slotsize- Returns:
- true if the range is a possible parameter
