Hello, 1. Which passes of gcc make use of points-to information in SSA_NAME_PTR_INFO (or more precisely, pt_solution) in doing optimizations?
2. Also, who computes this points-to information and populates pt_solution? Is it ONLY ipa-pta pass? When I accessed pt_solution through a plugin which REPLACES ipa-pta pass, I found that the information (in pt_solution) with and without ipa-pta pass differs only in terms of flags in pt_solution. Here with the examples I could construct, I found that the bitmap 'vars' in pt_solution is same for both the cases. Is it always true? Can someone please help in clarifying these doubts. Thanks in advance. -- Regards, Nikhil Patil.
