FWIW I'm still baffled by this shader bit. NaNs are absolutely required to be generated and handled as NaNs in shaders (albeit conversion to ints will make them 0) by DX10 (there's plenty of tests which actually check for this). And generally, you really want to generate NaNs for newer glsl versions too I think, albeit this may not be strictly required (of course, currently you can't distinguish this in tgsi, but particularly gs/ls/hs will always be newer glsl versions). So I'm REALLY wondering why there's a shader bit named that way...
