Compile DirectX Shaders from Go
dxc is both a library and an executable to compile DirectX shaders and
effects. It uses the D3DCompiler_XX.dll DLLs that come with any Windows system.
To install the binary dxc.exe, run
go install github.com/gonutz/dxc/cmd/dxc@latest
See the online documentation for how to use the library.
Command Line Tool
The cmd/dxc folder contains a command line version of this tool.
dxc takes its input from stdin and outputs the shader code to stdout. Errors
go to stderr.
Example:
dxc -WX -T vs_2_0 < vertex_shader.hlsl > vertex_shader_blob.bin
Usage of dxc:
-E string
entrypoint name (default "main")
-Gch
compile as a child effect for FX 4.x targets
-Gdp
disable effect performance mode
-Gec
enable backwards compatibility mode
-Ges
enable strict mode
-Gfa
avoid flow control constructs
-Gfp
prefer flow control constructs
-Gis
force IEEE strictness
-Gpp
force partial precision
-O int
optimization level 0..3 (default 1)
-Od
disable optimizations, only use this for debug builds
-Op
disable preshaders
-T string
target profile, e.g. vs_2_0, ps_4_1, fx_5_0 etc.
-Vd
disable validation
-WX
treat warnings as errors
-Zi
enable debug information in output
-Zpc
pack matrices in column-major order
-Zpr
pack matrices in row-major order
-res_may_alias
assume that UAVs/SRVs may alias for cs_5_0+
