For Solaris 8 1/01 release, Linker and Libraries Guide has been updated with the following information.

• The symbolic information available from dladdr(3DL) has been enhanced with the introduction of dladdr1().

• The $ORIGIN of a dynamic object can be obtained from dlinfo(3DL).

• The maintenance of runtime configuration files, created with crle(1), has been simplified with the display of the command-line options that were used to create the configuration file. Also available is an update capability (see the -u option).

• The runtime linker and its debugger interface have been extended to detect procedure-linkage-table entry resolution. This update is identified by a new version number. See rd_init()() under Agent Manipulation. This update extends the rd_plt_info_t structure. See rd_plt_resolution()() under Procedure Linkage Table Skipping.

• An applications stack can be defined non-executable using the new mapfile segment descriptor STACK. See Segment Declarations.

For the Solaris 8 10/00 release,Linker and Libraries Guide has been updated with the following new information.

• The environment variable LD_BREADTH is ignored by the runtime linker. See the section, "Initialization and Termination Routines."

• The runtime linker and its debugger interface have been extended for better runtime and core file analysis. This update is identified by a new version number. See the rd_init() function in the section "Agent Manipulation." This update expands the rl_flags, rl_bend, and rl_dynamic fields of the rd_loadobj_st structure. See the section "Scanning Loadable Objects."

• The validation of displacement-relocated data in regard to its use, or possible use, with copy relocations is now provided. See the section "Displacement Relocations."

• 64-bit filters can be built solely from a mapfile by using the link-editors -64 option. See the section "Generating a Standard Filter."

• Some explanatory notes are provided on why $ORIGIN dynamic string token expansion is restricted within secure applications. See the section "Security."

• The search paths that are used to locate the dependencies of dynamic objects can be inspected by using dlinfo(3DL).

• dlsym(3DL) and dlinfo(3DL) look-up semantics have been expanded with a new handle, RTLD_SELF.

• The runtime symbol look-up mechanism that is used to relocate dynamic objects can be significantly reduced by establishing direct binding information within each dynamic object. See the section "External Bindings and Direct Binding."
