--- Comment #1 from Ilia Mirkin <imir...@alum.mit.edu> ---
These also fail on r600. This is probably a st/mesa-level or glsl ir-level
issue. Haven't gotten any confirmation from anyone using i965, but I'm
reassigning this to mesa core.
I suspect that the following is the cause of the trouble:
b[1] = a[1];
c[1] += d[1];
a[1] += 1.0;
If the += 1 gets reordered to before the b[1] = a[1], then we're in trouble. I
get cyan as the output, with 182 for the first component, which means that
if(b[1] == 1.0) q += 2.0;
is failing. Haven't quite figured out how to convert these webgl tests into
piglits quite yet, although this one should be easy since it's not
input-dependent.
