Subject: i915: Add support for gl_FragData[0] reads.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b094b3b9f4c7b40056c31e3480ab7dc530da56e7;p=mesa.git

i915: Add support for gl_FragData[0] reads.

Similar to 556a47a2621073185be83a0a721a8ba93392bedb, without this reading from
gl_FragData[0] would cause a software fallback.
