Oracle Solaris 11.4 Release

Encapsulation symbols can be created to capture the range of an allocatable section. See Encapsulation Symbols.
Deferred references can now be defined on a per-symbol basis. See Providing an Alternative to dlopen and Deferred Symbol References.
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.
Standard functions for section compression and decompression have been added to libelf. elf_compress(3ELF), elf_compress_gnu(3ELF), elf32_getchdr(3ELF), elf64_getchdr(3ELF), and gelf_getchdr(3ELF).
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).
Oracle Solaris ELF objects provide names for program headers that represent mapping segments. These names are displayed by elfdump(1), elfedit(1), mdb(1), pmap(1), and pmadvise(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 /.
