You have: > +#define GLIBC_DYNAMIC_LINKER_LP64 "/lib64/ld.so.1"
See my comments on the glibc patch series <https://sourceware.org/pipermail/libc-alpha/2021-August/130298.html>. Specifically, the point that all new glibc ports should have unique per-ABI dynamic linker names for each ABI supported by the port, preferably referencing the architecture name somewhere in the dynamic linker name. /lib64/ld.so.1 is a name that's already in use, so should not be used by any ABI of this new port. > + error ("%<-march=%s%> does not work on a cross compiler.", Error messages should not end with '.'. > + error ("%<-mtune=%s%> does not work on a cross compiler.", Likewise. I didn't see any additions to contrib/config-list.mk anywhere in the patch series. (See "Back End" in sourcebuild.texi for a list of places you may need to update as part of a GCC port, including config-list.mk.) Please make sure the back end builds cleanly with current GCC mainline. This can be tested either with a native bootstrap, or by building a cross compiler, using a native compiler of the same GCC mainline version for the build and configuring using --enable-werror-always (that configure option has the effect of enabling -Werror in the same way that later bootstrap stages in a native bootstrap do). -- Joseph S.
