Instead of doing the canonicalization inside forwprop, Richi mentioned we should do it inside fold_stmt_1 and that is what this patch does. PR tree-optimization/102216 gcc/ChangeLog: * gimple-fold.c (fold_stmt_1): Add canonicalization of "&MEM[ssa_n, CST]" to "ssa_n p+ CST", note this can only be done if !in_place. gcc/testsuite/ChangeLog: * g++.dg/tree-ssa/pr102216-1.C: New test. * g++.dg/tree-ssa/pr102216-2.C: New test.
