From: Zack Rusin Date: Sat, 27 Apr 2013 04:49:23 +0000 (-0400) Subject: draw/so: indicate overflow when buffer is missing X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0031cde1e199a82dfe4b754931fb0a5bdf5582f9;p=mesa.git draw/so: indicate overflow when buffer is missing We were crashing if one of the buffers wasn't set, we should just treat it as an overflow. It's useful when using so statistics because it allows one to figure out how much data would be generated by so without actually writing any of it.
