821 | (* the following is no longer used. |
822 | the goal was to let one put a statement at the very beginning of a function | |
823 | pattern and have it skip over the declarations in the C code. | |
824 | that feature was removed a long time ago, however, in favor of | |
825 | ... when != S, which also causes whatever comes after it to match the | |
826 | first real statement. | |
827 | the separation of declarations from the rest of the body means that the | |
828 | quantifier of any variable shared between them comes out too high, posing | |
829 | problems when there is ... decl ... stmt, as the quantifier of any shared | |
830 | variable will be around the whole thing, making variables not free enough | |
831 | in the first ..., and thus not implementing the expected shortest path | |
832 | condition. example: f() { ... int A; ... foo(A); }. | |
833 | the quantifier for A should start just before int A, not at the top of the | |
834 | function. | |
