Function Documentation

bool fncNameFromCst	(	const char **	pName,
		const struct cl_operand *	op
	)

get name of an external function given as CL_OPERAND_CST, true on success

bool fncUidFromOperand	(	int *	pUid,
		const struct cl_operand *	op
	)

get uid of a function from the given operand if available, true on success

int intCstFromOperand

(

const struct cl_operand *

op)

return integral value from the integral constant given as operand

bool isLcVar ( const cl_operand &  op)

int offsetByIdxChain	(	const struct cl_type *	,
		const TFieldIdxChain &
	)

bool operator!= ( const struct cl_type &  cltA, const struct cl_type &  cltB  )

inline

compare given two pieces of static type-info semantically

Definition at line 44 of file clutil.hh.

bool operator==	(	const struct cl_type &	cltA,
		const struct cl_type &	cltB
	)

compare given two pieces of static type-info semantically

bool seekRefAccessor

(

const struct cl_accessor *

ac)

return true if there is any CL_ACCESSOR_REF in the given chain of accessors

Note

CL_ACCESSOR_REF accessors can't be chained with each other, as it makes semantically no sense

struct cl_type* targetTypeOfArray

(

const struct cl_type *

clt)

return type of the target object that the array type can point to

struct cl_type* targetTypeOfPtr

(

const struct cl_type *

clt)

return type of the target object that the pointer type can point to

int varIdFromOperand	(	const struct cl_operand *	op,
		const char **	pName = 0
	)

return unique ID of the variable/register given as operand

std::string varToString	(	const CodeStorage::Storage &	stor,
		const int	uid,
		const struct cl_loc **	pLoc = 0
	)
