Software testing concept used for MAS/C-compiler

The paper presents a software testing concept used for MICRONAS Intermetall MAS DSP C compiler MAS/C-Compiler. The concept is based on a specially developed software testing tool, which asserts whether the application generated by MAS/C-Compiler is valid or not. If not, it helps compiler designers to localize the bug, and to eliminate it. Compiler testing is viewed as a continual process. For each new compiler test case, the following two steps are conducted: (i) reference error-free source code is designed using commercially available high quality C++ reference compilers; (ii) a specially developed bit-exact testing tool is used to compare outputs of application produced by reference compiler and application produced by MAS/C-Compiler. Based on this comparison, bug localization and elimination is possible.
