Subject: translate_generic: fix broken A8R8G8B8_UNORM output
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=684aeb366fb72a2dbf9dd7a0803f29880858cd06;p=mesa.git

translate_generic: fix broken A8R8G8B8_UNORM output

translate was attempting to output A8R8G8B8_UNORM as if it were
R8G8B8A8_UNORM.

Now the tests just added pass.
