Method Detail

assignMap

void assignMap(Program prog,
               DataType[] proto,
               java.util.ArrayList<VariableStorage> res,
               boolean addAutoParams)

Given a list of datatypes, calculate the storage locations used for passing those datatypes

Parameters:

prog - is the active progra

proto - is the list of datatypes

res - is the vector for holding the VariableStorage corresponding to datatypes

addAutoParams - if true add/process auto-parameters

saveXml

void saveXml(java.lang.StringBuilder buffer,
             boolean isInput)

restoreXml

void restoreXml(XmlPullParser parser,
                CompilerSpec cspec)
         throws XmlParseException

Throws:

XmlParseException

getPotentialRegisterStorage

VariableStorage[] getPotentialRegisterStorage(Program prog)

Get a list of all parameter storage locations consisting of a single register

Parameters:

prog - is the controlling program

Returns:

an array of VariableStorage

getStackParameterAlignment

int getStackParameterAlignment()

Return the amount of alignment used for parameters passed on the stack, or -1 if there are no stack params

Returns:

the alignment

getStackParameterOffset

java.lang.Long getStackParameterOffset()

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

Returns:

the boundary offset

possibleParamWithSlot

boolean possibleParamWithSlot(Address loc,
                              int size,
                              ParamList.WithSlotRec res)

Determine if a particular address range is a possible parameter, and if so what slot(s) it occupies

Parameters:

loc - is the starting address of the range

size - is the size of the range in bytes

res - holds the resulting slot and slotsize

Returns:

true if the range is a possible parameter

isThisBeforeRetPointer

boolean isThisBeforeRetPointer()
