## Detailed Description

A halide module.

This represents IR containing lowered function definitions and buffers.

Definition at line 142 of file Module.h.

## Constructor & Destructor Documentation

## Module()

Halide::Module::Module | ( | const std::string & | name,
|  | const Target & | target,
|  | const MetadataNameMap & | metadata_name_map = {} )

References name(), and target().

Referenced by append(), and resolve_submodules().

## Member Function Documentation

## target()

const Target & Halide::Module::target | ( |  | ) | const

Get the target this module has been lowered for.

Referenced by Module().

## name()

const std::string & Halide::Module::name | ( |  | ) | const

The name of this module.

This is used as the default filename for output operations.

Referenced by get_function_by_name(), and Module().

## get_auto_scheduler_results()

const AutoSchedulerResults * Halide::Module::get_auto_scheduler_results | ( |  | ) | const

If this Module had an auto-generated schedule, return a read-only pointer to the AutoSchedulerResults.

If not, return nullptr.

## any_strict_float()

bool Halide::Module::any_strict_float | ( |  | ) | const

Return whether this module uses strict floating-point anywhere.

Referenced by set_any_strict_float().

## buffers()

const std::vector< Buffer< void > > & Halide::Module::buffers | ( |  | ) | const

The declarations contained in this module.

## functions() [1/2]

const std::vector< Internal::LoweredFunc > & Halide::Module::functions | ( |  | ) | const

## functions() [2/2]

std::vector< Internal::LoweredFunc > & Halide::Module::functions | ( |  | ) |

## submodules()

const std::vector< Module > & Halide::Module::submodules | ( |  | ) | const

## get_cuda_ptx_assembly_buffer()

Buffer Halide::Module::get_cuda_ptx_assembly_buffer | ( |  | ) | const

Tries to locate the offloaded CUDA PTX assembly contained in this Module.

Might return a nullptr in case such buffer is not present in this Module.

## get_device_code_buffer()

Buffer Halide::Module::get_device_code_buffer | ( |  | ) | const

Tries to locate the offloaded (GPU) Device assembly contained in this Module.

This can be any of the GPU kernel sources, etc...

## get_function_by_name()

Internal::LoweredFunc Halide::Module::get_function_by_name | ( | const std::string & | name | ) | const

Return the function with the given name.

If no such function exists in this module, assert.

References name().

## append() [1/3]

void Halide::Module::append | ( | const Buffer< void > & | buffer | ) |

Add a declaration to this module.

## append() [2/3]

void Halide::Module::append | ( | const Internal::LoweredFunc & | function | ) |

## append() [3/3]

void Halide::Module::append | ( | const Module & | module | ) |

References Module().

## compile()

void Halide::Module::compile | ( | const std::map< OutputFileType, std::string > & | output_files | ) | const

Compile a halide Module to variety of outputs, depending on the fields set in output_files.

## compile_to_buffer()

Buffer< uint8_t > Halide::Module::compile_to_buffer | ( |  | ) | const

Compile a halide Module to in-memory object code.

Currently only supports LLVM based compilation, but should be extended to handle source code backends.

## resolve_submodules()

Module Halide::Module::resolve_submodules | ( |  | ) | const

Return a new module with all submodules compiled to buffers on on the result Module.

References Module().

## remap_metadata_name()

void Halide::Module::remap_metadata_name | ( | const std::string & | from,
|  | const std::string & | to ) const

When generating metadata from this module, remap any occurrences of 'from' into 'to'.

## get_metadata_name_map()

MetadataNameMap Halide::Module::get_metadata_name_map | ( |  | ) | const

Retrieve the metadata name map.

## set_auto_scheduler_results()

void Halide::Module::set_auto_scheduler_results | ( | const AutoSchedulerResults & | results | ) |

Set the AutoSchedulerResults for the Module.

It is an error to call this multiple times for a given Module.

## set_any_strict_float()

void Halide::Module::set_any_strict_float | ( | bool | any_strict_float | ) |

Set whether this module uses strict floating-point directives anywhere.

References any_strict_float().

## set_conceptual_code_stmt()

void Halide::Module::set_conceptual_code_stmt | ( | const Internal::Stmt & | stmt | ) |

Remember the Stmt during lowing before device-specific offloading.

## get_conceptual_stmt()

const Internal::Stmt & Halide::Module::get_conceptual_stmt | ( |  | ) | const

Get the remembered conceptual Stmt, remembered before device-specific offloading.
