--- Comment #9 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Created attachment 37075 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37075&action=edit Updated patch, which adds a "sorry" when the problem first occurs Here's a new patch. Unfortunately, with this new patch, it fails bootstrap here: gimple-match.c: In function ‘bool gimple_simplify_LSHIFT_EXPR(code_helper*, tree_node**, gimple**, tree_node* (*)(tree), code_helper, tree, tree, tree)’: gimple-match.c:50437:0: sorry, unimplemented: -Wmisleading-indentation is disabled from this point onwards, since column-tracking was disabled due to the size of the code/headers std::swap (o30, o31); actually here: if (tree_swap_operands_p (o30, o31, false)) std::swap (o30, o31); We may need to fix things so that we're less likely to run into the LINE_MAP_MAX_LOCATION_WITH_COLS limit.
