InputPatch parameters to patch constant functions were not using the internal (temporary) variable type. That could cause validation errors if the input patch had a mixture of builtins and user qualified members. This uses the entry point's internal form. There is currently a limitation: if an InputPatch is used in a PCF, it must also have appeared in the main entry point's parameter list. That is not a limitation of HLSL. Currently that situation is detected and an "implemented" error results. The limitation can be addressed, but isn't yet in the current form of the PR.

// Test mixed InputPatch structure: user and builtin members. Hull shaders involve extra

// logic in this case due to patch constant function call synthesis.

// This example tests the PCF EP having an InputPatch, but the main EP does not.
