--- Comment #4 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > Is your compiler configured with --enable-checking=rtl ? Yes, but I don't think Rainer's is. > Perhaps it can be only reproduced natively, or relies on particular > auto-host.h content (I don't have cross-binutils to Solaris around). Or it was fixed by your emit-rtl.c change.
