# 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).
