Shader Module Compilation Options

Shader module compilation options may be specified to override Dawn's default compilation behavior.

wgpu::ShaderModuleCompilationOptions may be chained on wgpu::ShaderModuleDescriptor. If it is, Dawn will use these compilation options instead of its defaults.

wgpu::ShaderModuleCompilationOptions::strictMath

Enables or disables strict math. When strict math is disabled, generally the compiler will:

• Assume no NaNs
• Assume no Inf
• Assume no signed 0
• Use multiplication by reciprocal instead of division
• Allow algebraic transformations according to associative and distribute properties.

It is implemented only on Metal and D3D.
