New Revision: 363263
URL: https://svnweb.freebsd.org/changeset/base/363263
Log:
Include ABI note tag in shared libraries.
Split the ELF feature note into a separate file that is linked into
*crt1.o the same as crtbrand.S was before. crtbrand.o is now linked
into crti.o on all platforms in addition to *crt1.o.
This is pretty handy; any chance we can backport this series for 12.3?
So there is an issue I need to resolve in that the notes can get lost if you
use --gc-sections which LLVM does when building the cross toolchain (so the
trick of using .comdat for notes doesn't end up working out). Right now it
only fully breaks RISC-V since all the other arches still have FreeBSD set
as the ELF OSABI in the ELF header.
