Subject: main: add binary support to GetProgramBinary
X-Git-Tag: upstream/18.1.0~3347
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7ee54ad057f05881d650443de13a6bf8099e7922;p=platform%2Fupstream%2Fmesa.git

main: add binary support to GetProgramBinary

V2: call generic _mesa_get_program_binary() helper rather than driver
    function directly to allow greater code sharing.
