Function Documentation

Build()

ffi::Module tvm::codegen::Build	(	IRModule	mod,
		Target	target
	)

Build a module from array of lowered function.

Parameters

mod	The Module to be built
target	The target to be built.

Returns

The result runtime::Module.

DeserializeModuleFromBytes()

ffi::Module tvm::codegen::DeserializeModuleFromBytes

(

std::string

blob

)

Deserialize runtime module including its submodules.

Parameters

blob	byte stream, which are generated by SerializeModuleToBytes.

Returns

runtime::Module runtime module constructed from the given stream

PackImportsToC()

std::string tvm::codegen::PackImportsToC	(	const ffi::Module &	m,
		bool	system_lib,
		const std::string &	c_symbol_prefix = ""
	)

Pack imported device library to a C file. Compile the C file and link with the host library will allow the DSO loader to automatically discover and import the dependency from the shared library.

Parameters

m	The host module with the imports.
system_lib	Whether expose as system library.
c_symbol_prefix	Optional symbol prefix of the blob symbol.

Returns

cstr The C string representation of the file.

PackImportsToLLVM()

ffi::Module tvm::codegen::PackImportsToLLVM	(	const ffi::Module &	m,
		bool	system_lib,
		const std::string &	target_triple,
		const std::string &	c_symbol_prefix = ""
	)

Pack imported device library to a LLVM module. Compile the LLVM module and link with the host library will allow the DSO loader to automatically discover and import the dependency from the shared library.

Parameters

m	The host module with the imports.
system_lib	Whether expose as system library.
target_triple	LLVM target triple
c_symbol_prefix	Optional symbol prefix of the blob symbol.

Returns

runtime::Module The generated LLVM module.

SerializeModuleToBytes()

std::string tvm::codegen::SerializeModuleToBytes	(	const ffi::Module &	mod,
		bool	export_dso = true
	)

Serialize runtime module including its submodules.

Parameters

mod	The runtime module to serialize including its import tree.
export_dso	By default, include the info of DSOExportable modules. If disabled, an error will be raised when encountering DSO modules.
