Subject: Use RGBA_LOGICOP_ENABLED() instead of ctx->Color._LogicOpEnabled since we often
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7a9c7c1133d5cf17d032c8568e8f040a7c171a72;p=mesa.git

Use RGBA_LOGICOP_ENABLED() instead of ctx->Color._LogicOpEnabled since we often
need to check for this condition before the later field has been computed.
Fixes logicop bug #8860.
