How the FX9 pre-parser treats legacy D3D9/SM3 constructs in the shader body.

public enum FxSourceMode

Fields

PreserveSm3 = 1

Preserve D3D9 constructs verbatim for an SM1–3 backend (the FNA fx_2_0 target — vkd3d's D3D_BYTECODE accepts sampler_state initializers, texture declarations, tex2D and COLOR semantics natively). Technique/pass and parameter-annotation blocks are still stripped and captured as metadata.

RewriteToSm4 = 0

Rewrite D3D9 constructs forward to SM4 for DXC (sampler_state → SamplerState + Texture2D, texture → Texture2D, tex2D → .Sample, COLOR → SV_Target). The default — the MonoGame OpenGL/DirectX/Vulkan pipeline.
