Subject: Mark internal implementation functions as hidden
X-Git-Tag: v16.06-rc1~333
X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=c15cc30571730e275bca061b469d18e2cfd484cf;p=vpp.git

Mark internal implementation functions as hidden

Adding hidden attribute results in compilation failure if the symbol is
not found when linking the .so. It should also lead to better
performance, as it side-steps GOT.
