From: Timothy Arceri Date: Wed, 7 Jun 2017 02:19:13 +0000 (+1000) Subject: mesa: stop passing state bitfield to UpdateState() X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f77740f14b9057de09e61e1abf086f08a68c5a1b;p=mesa.git mesa: stop passing state bitfield to UpdateState() The code comment which seems to have been added in cab974cf6c2db (from year 2000) says: "Set ctx->NewState to zero to avoid recursion if Driver.UpdateState() has to call FLUSH_VERTICES(). (fixed?)" As far as I can tell nothing in any of the UpdateState() calls should cause it to be called recursively. V2: add a wrapper around the osmesa update function so it can still be used internally.
