And for the before/after loops flag you added: we have a cfun->curr_properties field which can be used. We even already have a PROP_loops flag but that is set throughout compilation from CFG construction until the RTL loop optimizers, so can't be re-used for what is needed here. But you still could invent another PROP_ value instead of adding a new field in struct function. Ciao, Michael.
