Package Overview for TestFloat Release 2a John R. Hauser 1998 December 16 TestFloat is a program for testing that a floating-point implementation conforms to the IEC/IEEE Standard for Binary Floating-Point Arithmetic. TestFloat is distributed in the form of C source code. The TestFloat package actually provides two related programs: -- The `testfloat' program tests a system's floating-point for conformance to the IEC/IEEE Standard. This program uses the SoftFloat software floating-point implementation as a basis for comparison. -- The `testsoftfloat' program tests SoftFloat itself for conformance to the IEC/IEEE Standard. These tests are performed by comparing against a separate, slower software floating-point that is included in the TestFloat package. TestFloat depends on SoftFloat, but SoftFloat is not included in the TestFloat package. SoftFloat can be obtained through the Web page `http:// HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'. TestFloat is documented in three text files: testfloat.txt Documentation for using the TestFloat programs (both `testfloat' and `testsoftfloat'). testfloat-source.txt Documentation for porting and compiling TestFloat. testfloat-history.txt History of major changes to TestFloat. The following file is also provided: systemBugs.txt Information about processor bugs found using TestFloat. Other files in the package comprise the source code for TestFloat. Please be aware that some work is involved in porting this software to other targets. It is not just a matter of getting `make' to complete without error messages. I would have written the code that way if I could, but there are fundamental differences between systems that I can't make go away. You should not attempt to compile the TestFloat sources without first reading `testfloat-source.txt'. At the time of this writing, the most up-to-date information about TestFloat and the latest release can be found at the Web page `http:// HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/TestFloat.html'.
