                                 int... expected)

checkNumFields

public static int checkNumFields(String str,
                                 int expected1,
                                 int expected2)

getInstructionParts

public static String[] getInstructionParts(String str)

Given an instruction string, strip-off the execution type and return opcode and all input/output operands WITHOUT their data/value type. i.e., ret.length = parts.length-1 (-1 for execution type)

Parameters:

str - instruction string

Returns:

instruction parts as string array

getInstructionPartsWithValueType

public static String[] getInstructionPartsWithValueType(String str)

Given an instruction string, this function strips-off the execution type (CP or MR) and returns the remaining parts, which include the opcode as well as the input and output operands. Each returned part will have the datatype and valuetype associated with the operand. This function is invoked mainly for parsing CPInstructions.

Parameters:

str - instruction string

Returns:
