Encapsulation symbols can be created to capture the range of an allocatable section. See Encapsulation Symbols.
The following utilities are only delivered as 64-bit objects. ar(1), dump(1), elfcompress(1), elfdump(1), elfedit(1), elffile(1), elfwrap(1), ldd(1), mcs(1), nm(1), pvs(1), size(1), and strip(1). All utilities retain their ability to work with both 32-bit and 64-bit ELF objects.
Mapfiles can match symbol names against glob, regular expression, or literal text patterns, and generate replacement symbol names that incorporate substrings from the input names. See MATCH and MATCHREF Expressions.
ld(1) provides the –z sx option to control ASLR, NXHEAP, NXSTACK, ADIHEAP and ADISTACK security extensions within individual executables. The –z sx option supersedes the –z aslr, –z nxheap and –z nxstack options. See Requesting Security Extensions.
The dependencies of kernel modules can be listed by the new utility kldd(1).
The significant differences between two ELF files can be analyzed by the new utility elfdiff(1).
The –z sysroot option, in conjunction with the $SYSROOT/ prefix to the –L option, can be used to direct the link-editor to search for libraries within a system image other than the system root directory /. The use of a sysroot is useful in cross linking scenarios where objects are being built to run on a system other than the build system. See ld(1).
The –S option to ldd(1) specifies the system root to be applied to all objects located by path searching. By default path searching is interpreted relative to the system root directory /.
The following items have been made obsolete. These items provided internal, or seldom used features. Any existing use of the associated ELF definitions is ignored, however the definitions can still be displayed by tools such as elfdump(1).
This dynamic token would expand to the native instruction sets of a platform, and could be employed to represent filter, runpath and dependency definitions. This token is no longer expanded by the link-editor, or runtime linker.
Support for the execution of alternative objects, that were created using the –I, or –G options, has been removed. The DF_1_CONFALT flag, which identified an alternative object within the DT_FLAGS_1 dynamic entry, can no longer be created. Any existing object containing this flag is rejected by the runtime linker.
The –f, –i, –I, –g, –G, and –t AOUT options have been removed. Any use of these options result in an error condition.
The –a and –A options have new restrictions on their use. Only files can be redirected, not entire directories. Any use of these options must be preceded by a –o option.
Support for the SHF_ORDERED section header flag has been discontinued. This flag was never used in a shipping version of Oracle Solaris.
Support for the SHN_BEFORE and SHN_AFTER special section indexes used with SHF_ORDERED and SHF_LINK_ORDER has been deprecated. Their use is discouraged, but remains supported in objects with fewer than SHN_LORESERVE sections. See Extended Section Header.
