Subject: mesa: add stricter checks for float formats in the texstore memcpy path
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9e59ed59c17daeb4e77f9455ac8794307cc1cae2;p=mesa.git

mesa: add stricter checks for float formats in the texstore memcpy path

E.g. when the internal format was RGBA16F and the source was RG, it would use
memcpy.
