C Specification
The VkPipelineShaderStageCreateInfo structure is defined as:
// Provided by VK_VERSION_1_0
typedef struct VkPipelineShaderStageCreateInfo {
VkStructureType sType;
const void* pNext;
VkPipelineShaderStageCreateFlags flags;
VkShaderStageFlagBits stage;
VkShaderModule module;
const char* pName;
const VkSpecializationInfo* pSpecializationInfo;
} VkPipelineShaderStageCreateInfo;Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
flagsis a bitmask of VkPipelineShaderStageCreateFlagBits specifying how the pipeline shader stage will be generated. -
stageis a VkShaderStageFlagBits value specifying a single pipeline stage. -
moduleis optionally a VkShaderModule object containing the shader code for this stage. -
pNameis a pointer to a null-terminated UTF-8 string specifying the entry point name of the shader for this stage. -
pSpecializationInfois a pointer to a VkSpecializationInfo structure, as described in Specialization Constants, orNULL.
Description
If module is not VK_NULL_HANDLE, the shader code used by the
pipeline is defined by module.
If module is VK_NULL_HANDLE, the shader code is defined by the
chained VkShaderModuleCreateInfo if present.
If the shaderModuleIdentifier
feature is enabled, applications can omit shader code for stage and
instead provide a module identifier.
This is done by including a
VkPipelineShaderStageModuleIdentifierCreateInfoEXT struct with
identifierSize not equal to 0 in the pNext chain.
A shader stage created in this way is equivalent to one created using a
shader module with the same identifier.
The identifier allows an implementation to look up a pipeline without
consuming a valid SPIR-V module.
If a pipeline is not found, pipeline compilation is not possible and the
implementation must fail as specified by
VK_PIPELINE_CREATE_FAIL_ON_PIPELINE_COMPILE_REQUIRED_BIT.
When an identifier is used in lieu of a shader module, implementations may
fail pipeline compilation with VK_PIPELINE_COMPILE_REQUIRED for any
reason.

Note
The rationale for the relaxed requirement on implementations to return a pipeline with VkPipelineShaderStageModuleIdentifierCreateInfoEXT is that layers or tools may intercept pipeline creation calls and require the full SPIR-V context to operate correctly. ICDs are not expected to fail pipeline compilation if the pipeline exists in a cache somewhere. |
Applications can use identifiers when creating pipelines with
VK_PIPELINE_CREATE_LIBRARY_BIT_KHR.
When creating such pipelines, VK_SUCCESS may be returned, but
subsequently fail when referencing the pipeline in a
VkPipelineLibraryCreateInfoKHR struct.
Applications must allow pipeline compilation to fail during link steps with
VK_PIPELINE_CREATE_FAIL_ON_PIPELINE_COMPILE_REQUIRED_BIT as it may
not be possible to determine if a pipeline can be created from identifiers
until the link step.
