# The binaries in SRC_URI are generated by the following (roughly):
# * taking an amd64 stage3
# * adding USE=ada to make.conf
# * running `crossdev ${CHOST} --ex-gcc -S`
# * running `USE=ada ${CHOST}-emerge -v1 gcc`
# * copy /usr/${CHOST}/var/cache/binpkgs/sys-devel/gcc* into
# ada-bootstrap-${PV}-${CHOST}.gpkg.tar
#
# The full script is at https://github.com/thesamesam/sam-gentoo-scripts/blob/91558fb51c56a661d6f374507888ff67725ca660/build-ada-bootstraps.
#
# Binaries in SRC_URI are regular Gentoo binpkgs in the GPKG format.
#
# Note: of course, the used GCC on both CBUILD and CHOST
# must be the same version, correspond to ${PV} in ada-bootstrap,
# and be at most the newest stable GCC (ideally older).
