# 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"
# Zlib won't build without cloning. We need also to get rid of default
# Makefile and get our own version of zconf.h to avoid interactions
# between 32 and 64 bit builds.
# Also, the x86 architecture does not require alignment for multi-byte
# loads, so we can define UNALIGNED_OK for x86
else
# Avoid *.lo.bc from Parfait analyze (see also parfait.patch).

# mapfile for result linking. While the one used with configure is just
# to allow Zlib detect capability of creating shared libraries.
