--- Comment #38 from Niels Möller <nisse at lysator dot liu.se> --- Just a brief update. 1. Tried adding fprintf warnings to c_gimplify_expr (btw, what's the right way to display a pretty warning with line numbers etc in later passes?). But it seems that's too early, I still get warnings for dead code. 2. The pass_remove_useless_stmts, mentioned in the docs, was deleted in 2009 (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=41573), and I take it it was obsoleted earlier, since there's no mention of a replacement. So what pass should I look at that is related to basic control flow analysis, and discarding unreachable statements?
