Add basic HS/DS implementation. This obsoletes WIP PR #704, which was built on the pre entry point wrapping master. New version here uses entry point wrapping. This is a limited implementation of tessellation shaders. In particular, the following are not functional, and will be added as separate stages to reduce the size of each PR. * patchconstantfunctions accepting per-control-point input values, such as const OutputPatch <hs_out_t, 3> cpv are not implemented. * patchconstantfunctions whose signature requires an aggregate input type such as a structure containing builtin variables. Code to synthesize such calls is not yet present. These restrictions will be relaxed as soon as possible. Simple cases can compile now: see for example Test/hulsl.hull.1.tesc - e.g, writing to inner and outer tessellation factors. PCF invocation is synthesized as an entry point epilogue protected behind a barrier and a test on invocation ID == 0. If there is an existing invocation ID variable it will be used, otherwise one is added to the linkage. The PCF and the shader EP interfaces are unioned and builtins appearing in the PCF but not the EP are also added to the linkage and synthesized as shader inputs. Parameter matching to (eventually arbitrary) PCF signatures is by builtin variable type. Any user variables in the PCF signature will result in an error. Overloaded PCF functions will also result in an error. [domain()], [partitioning()], [outputtopology()], [outputcontrolpoints()], and [patchconstantfunction()] attributes to the shader entry point are in place, with the exception of the Pow2 partitioning mode.

vertices = 4
HLSL: pass tessellation execution modes through to SPIR-V The SPIR-V generator had assumed tessellation modes such as primitive type and vertex order would only appear in tess eval (domain) shaders. SPIR-V allows either, and HLSL allows and possibly requires them to be in the hull shader. This change: 1. Passes them through for either tessellation stage, and, 2. Does not set up defaults in the domain stage for HLSl compilation, to avoid conflicting definitions.

HLSL: allow mixed user & builtin members in hull shader output structure Hull shaders have an implicitly arrayed output. This is handled by creating an arrayed form of the provided output type, and writing to the element of it indexed by InvocationID. The implicit indirection into that array was causing some troubles when copying to a split structure. handleAssign was able to handle simple symbol lvalues, but not an lvalue composed of an indirection into an array.

HLSL: HS return is arrayed to match SPIR-V semantics HLSL HS outputs a per ctrl point value, and the DS reads an array of that type. (It also has a per patch frequency). The per-ctrl-pt frequency is arrayed on just one side, as opposed to SPIR-V which is arrayed on both. To match semantics, the compiler creates an array behind the scenes and indexes it by invocation ID, assigning the HS return value to it.

HLSL: support per control point patch const fn invocation This PR emulates per control point inputs to patch constant functions. Without either an extension to look across SIMD lanes or a dedicated stage, the emulation must use separate invocations of the wrapped entry point to obtain the per control point values. This is provided since shaders are wanting this functionality now, but such an extension is not yet available. Entry point arguments qualified as an invocation ID are replaced by the current control point number when calling the wrapped entry point. There is no particular optimization for the case of the entry point not having such an input but the PCF still accepting ctrl pt frequency data. It'll work, but anyway makes no so much sense. The wrapped entry point must return the per control point data by value. At this time it is not supported as an output parameter.

There is no particular optimization for the case of the entry point not having such an input but the PCF still accepting ctrl pt frequency data. It'll work, but anyway makes no so much sense. The wrapped entry point must return the per control point data by value. At this time it is not supported as an output parameter.

Add basic HS/DS implementation. This obsoletes WIP PR #704, which was built on the pre entry point wrapping master. New version here uses entry point wrapping. This is a limited implementation of tessellation shaders. In particular, the following are not functional, and will be added as separate stages to reduce the size of each PR. * patchconstantfunctions accepting per-control-point input values, such as const OutputPatch <hs_out_t, 3> cpv are not implemented. * patchconstantfunctions whose signature requires an aggregate input type such as a structure containing builtin variables. Code to synthesize such calls is not yet present. These restrictions will be relaxed as soon as possible. Simple cases can compile now: see for example Test/hulsl.hull.1.tesc - e.g, writing to inner and outer tessellation factors. PCF invocation is synthesized as an entry point epilogue protected behind a barrier and a test on invocation ID == 0. If there is an existing invocation ID variable it will be used, otherwise one is added to the linkage. The PCF and the shader EP interfaces are unioned and builtins appearing in the PCF but not the EP are also added to the linkage and synthesized as shader inputs. Parameter matching to (eventually arbitrary) PCF signatures is by builtin variable type. Any user variables in the PCF signature will result in an error. Overloaded PCF functions will also result in an error. [domain()], [partitioning()], [outputtopology()], [outputcontrolpoints()], and [patchconstantfunction()] attributes to the shader entry point are in place, with the exception of the Pow2 partitioning mode.

HLSL: HS return is arrayed to match SPIR-V semantics HLSL HS outputs a per ctrl point value, and the DS reads an array of that type. (It also has a per patch frequency). The per-ctrl-pt frequency is arrayed on just one side, as opposed to SPIR-V which is arrayed on both. To match semantics, the compiler creates an array behind the scenes and indexes it by invocation ID, assigning the HS return value to it.

HLSL: pass tessellation execution modes through to SPIR-V The SPIR-V generator had assumed tessellation modes such as primitive type and vertex order would only appear in tess eval (domain) shaders. SPIR-V allows either, and HLSL allows and possibly requires them to be in the hull shader. This change: 1. Passes them through for either tessellation stage, and, 2. Does not set up defaults in the domain stage for HLSl compilation, to avoid conflicting definitions.

This is a limited implementation of tessellation shaders. In particular, the following are not functional, and will be added as separate stages to reduce the size of each PR. * patchconstantfunctions accepting per-control-point input values, such as const OutputPatch <hs_out_t, 3> cpv are not implemented. * patchconstantfunctions whose signature requires an aggregate input type such as a structure containing builtin variables. Code to synthesize such calls is not yet present. These restrictions will be relaxed as soon as possible. Simple cases can compile now: see for example Test/hulsl.hull.1.tesc - e.g, writing to inner and outer tessellation factors. PCF invocation is synthesized as an entry point epilogue protected behind a barrier and a test on invocation ID == 0. If there is an existing invocation ID variable it will be used, otherwise one is added to the linkage. The PCF and the shader EP interfaces are unioned and builtins appearing in the PCF but not the EP are also added to the linkage and synthesized as shader inputs. Parameter matching to (eventually arbitrary) PCF signatures is by builtin variable type. Any user variables in the PCF signature will result in an error. Overloaded PCF functions will also result in an error. [domain()], [partitioning()], [outputtopology()], [outputcontrolpoints()], and [patchconstantfunction()] attributes to the shader entry point are in place, with the exception of the Pow2 partitioning mode.

HLSL: allow mixed user & builtin members in hull shader output structure Hull shaders have an implicitly arrayed output. This is handled by creating an arrayed form of the provided output type, and writing to the element of it indexed by InvocationID. The implicit indirection into that array was causing some troubles when copying to a split structure. handleAssign was able to handle simple symbol lvalues, but not an lvalue composed of an indirection into an array.

HLSL: HS return is arrayed to match SPIR-V semantics HLSL HS outputs a per ctrl point value, and the DS reads an array of that type. (It also has a per patch frequency). The per-ctrl-pt frequency is arrayed on just one side, as opposed to SPIR-V which is arrayed on both. To match semantics, the compiler creates an array behind the scenes and indexes it by invocation ID, assigning the HS return value to it.

HLSL: support per control point patch const fn invocation This PR emulates per control point inputs to patch constant functions. Without either an extension to look across SIMD lanes or a dedicated stage, the emulation must use separate invocations of the wrapped entry point to obtain the per control point values. This is provided since shaders are wanting this functionality now, but such an extension is not yet available. Entry point arguments qualified as an invocation ID are replaced by the current control point number when calling the wrapped entry point. There is no particular optimization for the case of the entry point not having such an input but the PCF still accepting ctrl pt frequency data. It'll work, but anyway makes no so much sense. The wrapped entry point must return the per control point data by value. At this time it is not supported as an output parameter.

HLSL: HS return is arrayed to match SPIR-V semantics HLSL HS outputs a per ctrl point value, and the DS reads an array of that type. (It also has a per patch frequency). The per-ctrl-pt frequency is arrayed on just one side, as opposed to SPIR-V which is arrayed on both. To match semantics, the compiler creates an array behind the scenes and indexes it by invocation ID, assigning the HS return value to it.

Add basic HS/DS implementation. This obsoletes WIP PR #704, which was built on the pre entry point wrapping master. New version here uses entry point wrapping. This is a limited implementation of tessellation shaders. In particular, the following are not functional, and will be added as separate stages to reduce the size of each PR. * patchconstantfunctions accepting per-control-point input values, such as const OutputPatch <hs_out_t, 3> cpv are not implemented. * patchconstantfunctions whose signature requires an aggregate input type such as a structure containing builtin variables. Code to synthesize such calls is not yet present. These restrictions will be relaxed as soon as possible. Simple cases can compile now: see for example Test/hulsl.hull.1.tesc - e.g, writing to inner and outer tessellation factors. PCF invocation is synthesized as an entry point epilogue protected behind a barrier and a test on invocation ID == 0. If there is an existing invocation ID variable it will be used, otherwise one is added to the linkage. The PCF and the shader EP interfaces are unioned and builtins appearing in the PCF but not the EP are also added to the linkage and synthesized as shader inputs. Parameter matching to (eventually arbitrary) PCF signatures is by builtin variable type. Any user variables in the PCF signature will result in an error.

HLSL: pass tessellation execution modes through to SPIR-V The SPIR-V generator had assumed tessellation modes such as primitive type and vertex order would only appear in tess eval (domain) shaders. SPIR-V allows either, and HLSL allows and possibly requires them to be in the hull shader. This change: 1. Passes them through for either tessellation stage, and, 2. Does not set up defaults in the domain stage for HLSl compilation, to avoid conflicting definitions.

The per-ctrl-pt frequency is arrayed on just one side, as opposed to SPIR-V which is arrayed on both. To match semantics, the compiler creates an array behind the scenes and indexes it by invocation ID, assigning the HS return value to it.

Add basic HS/DS implementation. This obsoletes WIP PR #704, which was built on the pre entry point wrapping master. New version here uses entry point wrapping. This is a limited implementation of tessellation shaders. In particular, the following are not functional, and will be added as separate stages to reduce the size of each PR. * patchconstantfunctions accepting per-control-point input values, such as const OutputPatch <hs_out_t, 3> cpv are not implemented. * patchconstantfunctions whose signature requires an aggregate input type such as a structure containing builtin variables. Code to synthesize such calls is not yet present. These restrictions will be relaxed as soon as possible. Simple cases can compile now: see for example Test/hulsl.hull.1.tesc - e.g, writing to inner and outer tessellation factors. PCF invocation is synthesized as an entry point epilogue protected behind a barrier and a test on invocation ID == 0. If there is an existing invocation ID variable it will be used, otherwise one is added to the linkage. The PCF and the shader EP interfaces are unioned and builtins appearing in the PCF but not the EP are also added to the linkage and synthesized as shader inputs. Parameter matching to (eventually arbitrary) PCF signatures is by builtin variable type. Any user variables in the PCF signature will result in an error. Overloaded PCF functions will also result in an error. [domain()], [partitioning()], [outputtopology()], [outputcontrolpoints()], and [patchconstantfunction()] attributes to the shader entry point are in place, with the exception of the Pow2 partitioning mode.
