Besides being the first patch implementing reflection, this patch introduces an
API problem with regard to D3DReflect() that will affect many different fields.
Namely, if the SM4 version token contains a nonsensical version D3DReflect()
will happily return it verbatim. As I see it our options are:
(1) return the token verbatim anyway instead of using struct
vkd3d_shader_version,
(2) don't use vkd3d_shader_scan() for wine's D3DReflect() [and either diverge
from native in vkd3d-utils' D3DReflect(), or don't use vkd3d_shader_scan()
there either]
(3) return the token verbatim in a separate field (and in a separate chained
structure?)
(4) punt, and use one of the above solutions if we ever do come across a shader
that contains insane data.
There are some other, similar problems:
* HLSL compile flags would be especially annoying to translate to e.g.
libvkd3d-shader compile arguments and then back again. (Frankly, it's already
annoying that we have to do that in the HLSL compiler.) This is basically the
same problem as the above, but it forms an argument for returning tokens
verbatim, or at least that one.
* Instruction counts (and I think everything else in the STAT chunk) are always
taken from the STAT chunk; if the STAT chunk is missing then D3DReflect() will
return zero, even though it could just count them. Should we preserve that
behaviour in libvkd3d-shader? in libvkd3d-utils?
