InstMap()

CGRAOmp::InstMap::InstMap ( )

inline

Constructor.

Member Function Documentation

add_custom_inst()

void InstMap::add_custom_inst	(	StringRef	opcode,
		ModuleAnalysisManager &	MAM
	)

add a custom instruction

Parameters

opcode	opcode string of the instruction (= the corresponding function name)
MAM	ModuleAnalysisManager

add_generic_inst()

Error InstMap::add_generic_inst

(

StringRef

opcode

)

add a generic instruction without mapping condition

Parameters

opcode

opcode string of the instruction

Returns

Error is returned if unknown opcode is specified

add_map_entry()

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

add an entry with a mapping condition

Parameters

opcode	opcode string of the instruction
map_cond	mapping condition instance

Returns

Error is returned if the opcode of an instruction is not added yet.

When a generic instruction is added to InstMap, a default entry, which matches any instruction with the same opcode, is added. This method is called, then the default entry is erased.

find() [1/2]

InstMapEntry * InstMap::find

(

Instruction *

I

)

find an entry for the instruction

Parameters

I	an instruction

Returns

a pointer of InstMapEntry is return if an entry is found. Otherwise, it return nullptr.

find() [2/2]

InstMapEntry * InstMap::find

(

StringRef

opcode

)

find an entry for the instruction

Parameters

opcode

opcode of the instruction

Returns

a pointer of InstMapEntry is return if an entry is found. Otherwise, it return nullptr.
