Subject: vc4: Report to shader-db how many threads a fragment shader has.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0fca01d0279c5794ae2aceee27668c974b586f87;p=mesa.git

vc4: Report to shader-db how many threads a fragment shader has.

Doing instruction count analysis when we emit the thread switches that
will save us from tons of stalls is kind of missing the point.
