From f1ddfa8512df62422db00281ce216eff7ec5706c Mon Sep 17 00:00:00 2001 From: Topi Pohjolainen Date: Tue, 12 Apr 2016 09:27:00 +0300 Subject: i965/blorp: Let compiler calculate the vertex buffer size Currently the size is sizeof(float) times too large. One reserves GEN6_BLORP_VBO_SIZE many floats whereas GEN6_BLORP_VBO_SIZE stands for the size of vertex buffer in bytes.
