--- Comment #6 from Paul Eggert <eggert at gnu dot org> --- (In reply to Martin Sebor from comment #5) > Patch posted for review: > https://gcc.gnu.org/ml/gcc-patches/2016-05/msg00013.html Thanks. This patch appears to address almost all the request, and it is definitely a step forward. Even with the change, I see no easy way in a constant expression to compute the bottom-order bits (ignoring overflow) of a signed integer value, but I can raise this issue as a separate enhancement request if it turns into a problem in practice.
