Subject: glsl: Fix setting of OutputsWritten for whole array dereference.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d00deae3ef3a7828de1e566ad95b3a5b1ab7034d;p=mesa.git

glsl: Fix setting of OutputsWritten for whole array dereference.

We just want to mark the whole thing used, not mark from each element
the whole size in use.  Fixes undefined URB entry writes on i965,
which blew up with debugging enabled.
