Doh! Thanks that will do. All the piglit regression I had found so far pass
when I run them alone, one by one.
Went back to Serious Sam 3 to isolate a shader that's causing problems. Found
one, shader 35. I get several errors like this :
error at : DOT4 __, t113@R14.x, t114F@R125.x
: expected operand value t113@R14.x, gpr contains R11.x.3||FP@R14.x
error at : DOT4 __, t85@R14.x, t86F@R124.x
: expected operand value t85@R14.x, gpr contains R11.x.3||FP@R14.x
error at : DOT4 __, t87@R13.y, t88F@R124.y
