--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Mon Sep 23 17:48:00 2019 New Revision: 276059 URL: https://gcc.gnu.org/viewcvs?rev=276059&root=gcc&view=rev Log: PR c++/91809 - bit-field and ellipsis. decay_conversion converts a bit-field access to its declared type, which isn't what we want here; it even has a comment that the caller is expected to have already used default_conversion to perform integral promotion. This function handles arithmetic promotion differently, but we still don't want to call decay_conversion before that happens. * call.c (convert_arg_to_ellipsis): Don't call decay_conversion for arithmetic arguments. Added: trunk/gcc/testsuite/g++.dg/overload/ellipsis4.C Modified: trunk/gcc/cp/ChangeLog trunk/gcc/cp/call.c
