<dawn>/test/tint/diagnostic_filtering/while_loop_attribute.wgsl:5:21 warning: 'dpdx' must only be called from uniform control flow
while (x > 0.0 && dpdx(1.0) > 0.0) {
^^^^^^^^^
<dawn>/test/tint/diagnostic_filtering/while_loop_attribute.wgsl:5:3 note: control flow depends on possibly non-uniform value
while (x > 0.0 && dpdx(1.0) > 0.0) {
^^^^^
