I have WIP patches to add support for the init arrays to our rtld. It is not tested yet, and I want to ponder more about the ABI changes in csu that I introduce. In fact, I am more interested in having answer to the question, what immediate and long-term use do we have for the feature. Also, I want non-artificial test cases for DT_INIT_ARRAY and DT_FINI_ARRAY. http://people.freebsd.org/~kib/misc/init_array.1.patch [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (FreeBSD) iEYEARECAAYFAk89JRIACgkQC3+MBN1Mb4jwbgCdEjrMOSnFnkNWvIH8+Gb4WnIk yWsAn1L8bWpl/TJ+gaDoIw5nZ9uj/tmS =qhbl -----END PGP SIGNATURE-----
