Respected Sir I am a M.E.Computer science student and doing project on induction variable optimization. Therefore i am reading the file tree-ssa-loop-ivopts.c of gcc-4.0.2 to know about what have implemented in that. Is there any other way to know about what have implemented yet and in gcc-4.0.2. Can i know the algorithm.? Please help me to figure it out. Thanking you. Rama Bharti Varshney id: 2005h103421 Bits-Pilani(Rajasthan) India.
