Open the CIPO recordAbstract From the Canadian patent
A compiler framework uses a generic "shell" or control and sequencing mechanism, and a generic back end (where the code generator is target-specific). The generic back end includes the functions of optimization register and memory allocation, and code generation. The shell may be executed on various host computers and the code generation function of the back end may be targeted for any of a number of computer architectures. A front end is tailored for each different source language, such as Cobol, Fortran Pascal, C, C+ +, Ada, etc. The front end scans and parses the source code modules, and generates from them an intermediate language ("IL") representation of the programs expressed in the …

Why it's free to use
- Filed February 18, 1992 and granted May 5, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 18, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 18, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
