摘要： Every time an assignment statement is executed during performing a simulation according to a second variable memory system, it is determined whether a value interpreted to have the same meaning is assigned to the assignment statement in the simulation according to a first variable memory system and in the simulation according to the second variable memory system. When the value interpreted to have the same meaning is not assigned, the value assigned according to the second variable memory system is overwritten by an expected value, and a report indicating that the assignment statement is a part dependent on a variable memory system is output.

摘要： According to an embodiment, a program generating apparatus includes a cross-compiling unit, a processing time calculating unit, a source code converting unit, and a self-compiling unit. The cross-compiling unit generates sin instruction string for each basic block based on a source code and specifies instructions performing a memory access. The processing time calculating unit calculates a processing time of the instruction string for each basic block. The source code converting unit inserts a first code, which adds the processing time of the basic block to an accumulated processing time variable of an executed thread of the basic block, and a second code, which calculates the processing time for the specified memory access and adds the calculated processing time to the accumulated processing time variable, into the source code. The self-compiling unit generates a performance estimating program outputting the accumulated processing time variable of the thread executed.
