Author: emaste Date: Wed Oct 2 02:32:58 2013 New Revision: 255983 URL: http://svnweb.freebsd.org/changeset/base/255983 Log: Populate .rld_map on MIPS for debuggers On MIPS the .dynamic section is read-only, so the pointer to rtld information for debuggers cannot be stored there (in DT_DEBUG). Instead, a special section .rld_map is used.
