Member Function Documentation

add_map_entry()

Error CGRAModel::add_map_entry	(	StringRef	opcode,
		MapCondition *	map_cond
	)

add a instruction mapping entry to the CGRA model

Parameters

opcode	opcode of the instruction to be replaced
map_cond	a mapping condition

Returns

Error is returned if the opcode is for unsupported instruction

addCustomInst()

void CGRAModel::addCustomInst	(	StringRef	opcode,
		ModuleAnalysisManager &	MAM
	)

add a custom insturction for the CGRA

Parameters

opcode	opcode of the instruction if it is already added instruction, this function does nothing
MAM	ModuleAnalysisManager

addSupportedInst()

Error CGRAModel::addSupportedInst

(

StringRef

opcode

)

add a supported generic insturction for the CGRA

Parameters

opcode

opcode of the instruction if it is already added instruction, this function does nothing

Returns

Error is returned if unknown opcode is specified

asDerived()

template<typename DerivedT >

DerivedT* CGRAOmp::CGRAModel::asDerived ( )

inline

an interface to down cast to derived classes

Template Parameters

DerivedT

derived class named

Returns

DerivedT* casted pointer to the derived class

getInterLoopDepType()

InterLoopDep CGRAOmp::CGRAModel::getInterLoopDepType ( ) const

inline

Get the Inter Loop Dependency avility.

Returns

InterLoopDep

getKind()

CGRACategory CGRAOmp::CGRAModel::getKind ( ) const

inline

Get the category of the CGRA.

Returns

CGRACategory

isSupported()

InstMapEntry * CGRAModel::isSupported

(

Instruction *

I

)

checking whether the instruction is supported by the CGRA or not.

Parameters

I	an instruction

Returns

a pointer of InstMapEntry is return if it is supported. Otherwise, it return nullptr.
