- List-id: Xen developer discussion <xen-devel.lists.xenproject.org>
I suspect it is commit 40726f16a8d7 ("ld script expression parsing")
which broke the hypervisor build, by no longer accepting section names
with a dash in them inside ADDR() (and perhaps other script directives
expecting just a section name, not an expression): .note.gnu.build-id
is such a section.
Quoting all section names passed to ADDR() via DECL_SECTION() works
around the regression.
