Subject: mesa/st+tgsi: Provide a free callback to match with ureg_get_tokens().
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=edbc302ad678e1a4a8803ba0e827a13dd27105d2;p=mesa.git

mesa/st+tgsi: Provide a free callback to match with ureg_get_tokens().

This fixes crashes with the memory debugging routines on Windows.

NOTE: This is a candidate for the 7.8 stable branch
