Subject: gallium: Add PUBLIC macro for function visibility.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=108c2bf5ab9228843d21c188d8819a54b1201d07;p=mesa.git

gallium: Add PUBLIC macro for function visibility.

As the default build has -fvisibility=hidden, add a macro to control the
visibility.
