--- Comment #10 from Fangrui Song <i at maskray dot me> --- Note: the section key is not just (name, group name "G"). It is a quadruple: (name, group name "G", linked-to "o", unique ID) Keeping just name works for the simplest case. If GCC decides to support PR95095 -fno-unique-section-names, unique ID can be common. https://sourceware.org/bugzilla/show_bug.cgi?id=25490#c3 added the support for `.section ....,unique` to GNU as.
