Solaris 2.6 Release

Weak symbol references can trigger archive member extraction by using the link-editor's -z weakextract option. Extracting all archive members can be achieved using the -z allextract option. See "Archive Processing".
Shared objects specified as part of a link-edit that are not referenced by the object being built can be ignored, and hence their dependency recording suppressed, using the link-editor's -z ignore option. See "Shared Object Processing".
The link-editor generates the reserved symbols _START_ and _END_ to provide a means of establishing an object's address range. See "Generating the Output File".
Changes have been made to the runtime ordering of initialization and finalization code to better accommodate dependency requirements. See "Initialization and Termination Routines".
Symbol resolution semantics have been expanded for dlopen(3DL). See "Symbol Lookup", RTLD_GROUP in "Isolating a Group", and RTLD_PARENT in "Object Hierarchies".
Symbol lookup semantics have been expanded with a new dlsym(3DL) handle RTLD_DEFAULT. See "Default Symbol Lookup Model".
Extensions have been made to filter processing that allow more than one filtee to be defined, and provide for forcibly loading filtees. See "Shared Objects as Filters".
You can record additional version dependencies using the mapfile file control directive $ADDVERS. See "Binding to Additional Version Definitions".
A runtime linker audit interface provides support for monitoring and modifying a dynamically linked application from within the process. See "Runtime Linker Auditing Interface".
A runtime linker debugger interface provides support for monitoring and modifying a dynamically linked application from an external process. See "Runtime Linker Debugger Interface".
Additional section information is supported. See Table 7-11 for SHN_BEFORE and SHN_AFTER. See Table 7-14 for SHF_ORDERED and SHF_EXCLUDE.
A new dynamic section tag, DT_1_FLAGS, is supported. See Table 7-44 for the various flag values.
A package of demonstration ELF programs is provided. See Chapter 7, Object File Format.
The link-editors now support internationalized messages. All system errors are reported using strerror(3C).
The new eliminate mapfile directive, or the -B eliminate option, enable you to elimination local symbol table entries. See "Symbol Elimination".

	Solaris 2.6 Release Weak symbol references can trigger archive member extraction by using the link-editor's `-z weakextract` option. Extracting all archive members can be achieved using the `-z allextract` option. See "Archive Processing". Shared objects specified as part of a link-edit that are not referenced by the object being built can be ignored, and hence their dependency recording suppressed, using the link-editor's `-z ignore` option. See "Shared Object Processing". The link-editor generates the reserved symbols `_START_` and `_END_` to provide a means of establishing an object's address range. See "Generating the Output File". Changes have been made to the runtime ordering of initialization and finalization code to better accommodate dependency requirements. See "Initialization and Termination Routines". Symbol resolution semantics have been expanded for `dlopen`(3DL). See "Symbol Lookup", `RTLD_GROUP` in "Isolating a Group", and `RTLD_PARENT` in "Object Hierarchies". Symbol lookup semantics have been expanded with a new `dlsym`(3DL) handle `RTLD_DEFAULT`. See "Default Symbol Lookup Model".
