--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- What is the host compiler? It is the host compiler that is failing with -mcpu=native. Can you add -v to the failing command in /var/tmp/portage/sys-devel/gcc-14.0.0.9999/work/build/build-aarch64-unknown-linux-gnu/libiberty , e.g. aarch64-unknown-linux-gnu-gcc -c -DHAVE_CONFIG_H -pipe -mcpu=native -fdiagnostics-color=always -ggdb3 -O2 -I. -I/var/tmp/portage/sys-devel/gcc-14.0.0.9999/work/gcc-14.0.0.9999/libiberty/../include -W -Wall -Wwrite-strings -Wc++-compat -Wstrict-prototypes -Wshadow=local -pedantic -D_GNU_SOURCE -fPIC /var/tmp/portage/sys-devel/gcc-14.0.0.9999/work/gcc-14.0.0.9999/libiberty/hashtab.c -o pic/hashtab.o -v
