◆ bindingName()

static std::string bindingName ( )
static

◆ calculateGlobalIndex()

static unsigned calculateGlobalIndex ( spirv::GlobalVariableOp  op)
static

Calculates the index of the kernel's operand that is represented by the given global variable with the bind attribute.

We assume that the index of each kernel's operand is mapped to (descriptorSet, binding) by the map: i -> (0, i) which is implemented under LowerABIAttributesPass.

◆ copy()

static void copy ( Location  loc,
Value  dst,
Value  src,
Value  size,
OpBuilder builder 
)
static

◆ createGlobalVariableWithBindName()

static std::string createGlobalVariableWithBindName ( spirv::GlobalVariableOp  op,
StringRef  kernelModuleName 
)
static

Encodes the binding and descriptor set numbers into a new symbolic name.

The name is specified by {kernel_module_name}_{variable_name}_descriptor_set{ds}_binding{b} to avoid symbolic conflicts, where 'ds' and 'b' are descriptor set and binding numbers.

◆ descriptorSetName()

static std::string descriptorSetName ( )
static

Returns the string name of the DescriptorSet decoration.

◆ getKernelGlobalVariables()

static LogicalResult getKernelGlobalVariables ( spirv::ModuleOp  module,
DenseMap< uint32_t, spirv::GlobalVariableOp > &  globalVariableMap 
)
static

Fills globalVariableMap with SPIR-V global variables that represent kernel arguments from the given SPIR-V module.

We assume that the module contains a single entry point function. Hence, all spv.GlobalVariables with a bind attribute are kernel arguments.

◆ hasDescriptorSetAndBinding()

static bool hasDescriptorSetAndBinding ( spirv::GlobalVariableOp  op)
static

Returns true if the given global variable has both a descriptor set number and a binding number.
