## GraphicsFuzz is a set of tools for testing shader compilers

GraphicsFuzz provides tools for automatically finding and simplifying bugs in graphics drivers,
specifically graphics shader compilers. The glsl-fuzz and glsl-reduce tools manipulate GLSL shaders, targeting SPIR-V compilers via translation.
The spirv-fuzz and spirv-reduce tools directly manipulate SPIR-V shaders.

## Download and run

Follow the [gfauto README](https://github.com/google/graphicsfuzz/tree/master/gfauto#gfauto).
The [gfauto](https://github.com/google/graphicsfuzz/tree/master/gfauto#gfauto) command line
tool is the
recommended way of automatically downloading and running our fuzzers to test Vulkan drivers in a "push-button" fashion with minimal interaction. See below if you want to read about
individual tools and/or use
them as standalone command line tools.
