Convert to data using information about operand value type (op_t::dtype). Emulator could use this function to convert unexplored bytes to data when an instruction references them. This function creates data only if the address was unexplored.

Parameters

ea_	linear address to be converted to data
opoff	offset of the operand from the start of instruction if the offset is unknown, then 0
dtype	operand value type (from op_t::dtype)

Return values

true	ok
false	failed to create data item

Convenient alias

Create or modify a stack variable in the function frame. The emulator could use this function to create stack variables in the function frame before converting the operand to a stack variable. Please check with may_create_stkvars() before calling this function.

Parameters

x	operand (used to determine the addressing type)
v	a displacement in the operand
flags_	Stack variable flags

Return values

1	ok, a stack variable exists now
0	no, couldn't create stack variable

Passed as 'flags' parameter to create_stkvar()
