47 | (* When in a semantic patch there is f(X) ... f(X) we want to force | |
48 | * the two X to be equal in the concrete code, but we would like that | |
49 | * there be equal modulo some isomorphisms, so that the following | |
50 | * concrete code also match: f(a && b) g(); f(b && a) | |
51 | ||
52 | * Maybe would be easier to transform ast_c in ast_cocci and call the | |
53 | * iso engine of julia. *) | |
