Hi,
just a couple of curiosities:

What's the point of the "fail" branch? If the shader doesn't produce "pass" it's already considered failing, isn't it?
The native preprocessor has the excellent behaviour of emitting an error when unable to parse an if condition and then outputting both branches without actually failing compilation. Which is to say that it emits a warning, only it uses the word "error".
We don't replicate this behaviour (yet).
Writing the test in this form validates both that native can actually parse the condition and that it's true.
+[preproc] +#if 012lu == 10 +pass +#endif
And why doesn't this have the "fail" branch?
Mostly because I was less worried about the idea that native couldn't parse the token when I wrote it.
