D3D12_SHADER_BYTECODE missing NativeArrayInfo

[morganbr]

D3D12_SHADER_BYTECODE (documented at https://learn.microsoft.com/windows/win32/api/d3d12/ns-d3d12-d3d12_shader_bytecode) is missing NativeArrayInfoAttribute on pShaderBytecode. It should use BytecodeLength as a length.

[MarijnS95]

It already has some form of annotation in IDL, _Field_size_bytes_full_:

win32metadata/generation/WinSDK/RecompiledIdlHeaders/um/d3d12.idl

Lines 847 to 851 in de9da38

	typedef struct D3D12_SHADER_BYTECODE
	{
	[annotation("_Field_size_bytes_full_(BytecodeLength)")] const void* pShaderBytecode;
	SIZE_T BytecodeLength;
	} D3D12_SHADER_BYTECODE;

But that doesn't seem to be parsed, as ILSpy for a Windows.Win32.winmd generated from that file shows:

[Documentation("https://learn.microsoft.com/windows/win32/api/d3d12/ns-d3d12-d3d12_shader_bytecode")]
public struct D3D12_SHADER_BYTECODE
{
	[Const]
	public unsafe void* pShaderBytecode;

	public UIntPtr BytecodeLength;
}

Perhaps the tooling needs to be updated to support this source attribute.

Alternatively we could have something manual in emitter.settings.rsp:

D3D12_SHADER_BYTECODE::pShaderBytecode=[NativeArrayInfo(CountParamIndex = 1)]
