C Specification

Values which may be returned in the denormBehaviorIndependence and roundingModeIndependence fields of VkPhysicalDeviceFloatControlsProperties are:

// Provided by VK_VERSION_1_2
typedef enum VkShaderFloatControlsIndependence {
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY = 0,
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_ALL = 1,
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_NONE = 2,
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY_KHR = VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY,
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_ALL_KHR = VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_ALL,
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_NONE_KHR = VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_NONE,
} VkShaderFloatControlsIndependence;

Description

  • VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY specifies that shader float controls for 32-bit floating point can be set independently; other bit widths must be set identically to each other.

  • VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_ALL specifies that shader float controls for all bit widths can be set independently.

  • VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_NONE specifies that shader float controls for all bit widths must be set identically.
