C Specification

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

typedef enum VkShaderFloatControlsIndependenceKHR {
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY_KHR = 0,
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_ALL_KHR = 1,
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_NONE_KHR = 2,
    VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_MAX_ENUM_KHR = 0x7FFFFFFF
} VkShaderFloatControlsIndependenceKHR;

Description

  • VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY_KHR 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_KHR specifies that shader float controls for all bit widths can be set independently.

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