a representation of instruction mapping condition

Constructor & Destructor Documentation

MapCondition() [1/3]

CGRAOmp::MapCondition::MapCondition ( StringRef  map )

inline

Parameters

map	a name which the instruction to be mapped to

MapCondition() [2/3]

CGRAOmp::MapCondition::MapCondition ( const MapCondition &  )

default

Copy constructor.

MapCondition() [3/3]

CGRAOmp::MapCondition::MapCondition ( MapCondition &&  )

default

Move Constructor.

~MapCondition()

CGRAOmp::MapCondition::~MapCondition ( )

inline

Destructor.

Member Function Documentation

dump()

void CGRAOmp::MapCondition::dump ( )

inline

equal_double()

static bool CGRAOmp::MapCondition::equal_double ( double  a, double  b  )

inlinestaticprivate

equality comparetor for double values

Parameters

a	one double value
b	the other double value

Returns

true if the two value seems to be the same.

otherwise false

getMapName()

std::string CGRAOmp::MapCondition::getMapName ( )

inline

get map name associated with this condition

Returns

string of map name

match()

bool MapCondition::match

(

Instruction *

I

)

test if the instruction satisfies the condition

Parameters

I	instruction to be tested

Returns

true in the case of satisfying the condition

otherwise false

print()

void MapCondition::print

(

raw_ostream &

OS

)

setConst() [1/2]

void MapCondition::setConst	(	double	use,
		bool	isLeft
	)

Set a condition for a constant operand the condition is met if an instruction has the same constant operand.

Parameters

use	a double value of the contant operant
isLeft	true if it is for the left hand side operand

setConst() [2/2]

void MapCondition::setConst	(	int	use,
		bool	isLeft
	)

Set a condition for a constant operand.

Parameters

use	an integer value of the contant operant
isLeft	true if it is for the left hand side operand

setFlags()

Error MapCondition::setFlags

(

ArrayRef< std::string >

flags

)

Set a condition for instruction flags the condition is met if an instruction has all the specified flags.

Parameters

flags

a list of the flag

Returns

Error is returned if unknown flag is included in the flags

setPred()

Error MapCondition::setPred

(

StringRef

pred

)

Set a condition for the predicate type of icmp/fcmp.

Parameters

pred	a predicate type

Returns

Error is returned if unknown predicate is specified
