  • Random test generation for compiler optimization
    Patent number: 6223337
    Abstract: An optimized compiler is tested. Code segments are stored in a segment file. Each code segment includes a description of an external interface with other segments. A source function is built using the code segments. The source function is compiled using optimization to produce first executable code. The source function is also compiled without using optimization to produce second executable code. The first executable code is executed to produce first results. The second executable code is executed to produce second results. The first results are compared with the second results. An error is reported when the first results differ from the second results.
