# We want to build hardware specific versions of the longest_match()
# function into our shared library that has been hand optimised to use
# some machine architecture specific instructions. Currently, we are doing
# it for the T4 architecture, but later other architectures may be added.
# This is done by taking advantage of the Solaris 11 linker-editor
# "Symbol Capabilities" feature.  Refer to the section "Creating a Family
# of Symbol Capabilities Functions", under "Identifying Capability
# Requirements" in the "Linker and Libraries Guide"
# (http://docs.oracle.com/cd/E19963-01/html/819-0690/chapter2-13.html#giskh).
