In SM1 we can expect all variables to always belong to a single regset.
structs in particular, should always be allocated to HLSL_REGSET_NUM,
since they are only allowed if all their components are numeric.
We are not covering the structs case because of the use of
hlsl_type_get_regset(), which is currently not defined for structs.
So the current shader
struct
{
float4 a;
float4 b;
} apple;
float4 main() : sv_target
{
return apple.a + apple.b;
}
fails with
vkd3d/libs/vkd3d-shader/hlsl.c:224: Aborting, reached unreachable code.
The solution is to iterate over all regsets to find the one where the
variable is allocated (if any), and ignore all others.
