hmm, thanks. it should have looked like this:
+ case TRY_FINALLY_EXPR:
+ case TRY_CATCH_EXPR:
+ array_offset_warning (&TREE_OPERAND (t, 0));
+ array_offset_warning (&TREE_OPERAND (t, 1));
+ break;
+ case CATCH_EXPR:
+ array_offset_warning (&CATCH_BODY (t));
+ break;
Anyway, I agree that the SSA pass after all const folding has happened is a
much better approach than my quick hack, as long as it isn't significantly
slower (compile time). I'm currently trying Falk's patch.
