D3D11_TRACE_REGISTER structure (d3d11shadertracing.h)
Describes a trace register.
Syntax
typedef struct D3D11_TRACE_REGISTER {
D3D11_TRACE_REGISTER_TYPE RegType;
union {
UINT16 Index1D;
UINT16 Index2D[2];
};
UINT8 OperandIndex;
UINT8 Flags;
} D3D11_TRACE_REGISTER;
Members
RegType
A D3D11_TRACE_REGISTER_TYPE-typed value that identifies the type of register that the shader-trace object uses.
Index1D
An index for one-dimensional arrays. This index is used by the following register types:
- vertex shader or pixel shader input: v[Index1D]
- temp: r[Index1D]
- output: o[Index1D]
- immediate constant buffer: icb[Index1D]
- sampler s[Index1D]
- resource r[Index1D]
- input patch constant register: vpc[Index1D]
- unordered access view: u[Index1D]
- thread group shared memory: g[Index1D]
Index2D[2]
An array of indexes for two-dimensional arrays. These indexes are used by the following register types:
- GS input: v[Index2D[0]][Index2D[1]]
- indexable temp: x[Index2D[0]][Index2D[1]]
- constant buffer: cb#[#]
- input control point register: vcp[Index2D[0]][Index2D[1]]
- output control point register: vocp[Index2D[0]][Index2D[1]]
OperandIndex
The index of the operand, which starts from 0.
Flags
A combination of the following flags that are combined by using a bitwise OR operation. The resulting value specifies more about the trace register.
| Flag | Description |
|---|---|
| D3D11_TRACE_REGISTER_FLAGS_RELATIVE_INDEXING (0x1) | Access to the register is part of the relative indexing of a register. |
Remarks
The following register types do not require an index:
- input PrimitiveID
- output oDepth
- immediate32
- NULL register
- output control point ID (this is actually an input; it defines the output that the thread controls)
- input fork instance ID
- input join instance ID
- input domain point register
- cycle counter
