signature

class numba.intrinsic.intrinsic.IntrinsicLibrary(context)

Bases: object

An intrinsic library maintains a LLVM module for holding the intrinsics. These are functions are used internally to implement specific features.

add(intr)

Add a new intrinsic. intr — an Intrinsic class

declare(module, name, arg_types=(), return_type=None)

Create a declaration in the module.

get(name, arg_types=(), return_type=None)

Get an intrinsic by name and sig

name — function name arg_types — function arg types return_types — function return type

Returns the function signature and a lfunc pointing to the

implement(intr)

Implement a new intrinsic. intr — an Intrinsic class

link(module)

Link the intrinsic library into the target module.

class numba.intrinsic.intrinsic.Signature

Bases: tuple

Signature(return_type, arg_types)

arg_types

Alias for field number 1

return_type

Alias for field number 0

numba.intrinsic.numba_intrinsic.declare_instruction(func_signature, name)

Declare an instruction, e.g.

>>> declare_instruction(int32(int32, int32), "add")

The llvm.core.Builder instruction with the given name will be used.

numba.intrinsic.numba_intrinsic.declare_intrinsic(func_signature, name)

Declare an intrinsic, e.g.

>>> declare_intrinsic(void(), "llvm.debugtrap")

numba.intrinsic.numba_intrinsic.is_numba_intrinsic(value)

numba.intrinsic.numba_intrinsic.make_intrinsic(intrinsic)

Create an intrinsic function given an Intrinsic.
