Just now, compiled mesa 10.6 branch and passed the tests with piglit's master:
$ for i in ./tests/shaders/glsl-derivs-*; do echo $i; ./bin/shader_runner $i
-auto -fbo; done
./tests/shaders/glsl-derivs-abs.shader_test
PIGLIT: {"result": "pass" }
./tests/shaders/glsl-derivs-abs-sign.shader_test
PIGLIT: {"result": "pass" }
./tests/shaders/glsl-derivs-sign.shader_test
PIGLIT: {"result": "pass" }
./tests/shaders/glsl-derivs-swizzle.shader_test
PIGLIT: {"result": "pass" }
./tests/shaders/glsl-derivs-varyings.shader_test
PIGLIT: {"result": "pass" }</pre>
