Is the expectation that hlsl_constant_ops.c is going to grow significantly in the future? As it is, hlsl_codegen.c isn't especially large, and could itself have been merged with hlsl.c.
+} \ No newline at end of file -- Well-formed C has newlines at the end of files. I know Alexandre's scripts fix these up on commit for Wine, and possibly vkd3d, but you'll nevertheless want to avoid omitting these. Typically this indicates having misconfigured your editor. (Or simply using the wrong editor. :D)

The file may get very large considering we may want to apply constant folding to all the intrinsic functions and operators, as the native compiler does. The file may end up holding several more boilerplate functions like the ones I sent in the next patches.

Sorry I missed that, I just configured my editor to highlight these and some other format mistakes.
