◆ GEN_PASS_DEF_LOWERHOSTCODETOLLVMPASS

#define GEN_PASS_DEF_LOWERHOSTCODETOLLVMPASS

Definition at line 36 of file ConvertLaunchFuncToLLVMCalls.cpp.

Function Documentation

◆ bindingName()

static std::string bindingName ( )
static

Returns the string name of the Binding decoration.

Definition at line 55 of file ConvertLaunchFuncToLLVMCalls.cpp.

◆ 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.

Definition at line 82 of file ConvertLaunchFuncToLLVMCalls.cpp.

◆ descriptorSetName()

static std::string descriptorSetName ( )
static

Returns the string name of the DescriptorSet decoration.

Definition at line 49 of file ConvertLaunchFuncToLLVMCalls.cpp.

◆ encodeKernelName()

static LogicalResult encodeKernelName ( spirv::ModuleOp  module)
static

Encodes the SPIR-V module's symbolic name into the name of the entry point function.

Definition at line 124 of file ConvertLaunchFuncToLLVMCalls.cpp.

References mlir::get(), kSPIRVModule, mlir::SymbolTable::replaceAllSymbolUses(), and mlir::SymbolTable::setSymbolName().

◆ 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 spirv.GlobalVariables with a bind attribute are kernel arguments.

Definition at line 106 of file ConvertLaunchFuncToLLVMCalls.cpp.

References calculateGlobalIndex(), and hasDescriptorSetAndBinding().

◆ 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.
