true if bit fields of a structure are packed from left (the most significant bit of 1st field is placed at the most significant bit of object).

costOfInstruction

public int costOfInstruction(int pIndex)

costOfInstruction Approximate cost of executing instructions in unit of register-register integer addition. The cost of each executable HIR node is assumed at least 1, so that the cost of (assign (exp e)) is assumed to be (1 + (cost of x) + (cost of e)). This value is used in HIR optimization, etc.

Parameters:

pIndex - is the index to select instruction in such way as COST_INDEX_TEMP_LOAD, COST_INDEX_CALL, etc.

Returns:

the approximate cost of instruction specified by pIndex.
