target

struct target

An interface for a compilation target.

Public Functions

std::string name() const

A unique name used to identify the target.

std::vector<pass> get_passes(context &ctx, const compile_options &options) const

The transformation pass to be run during compilation.

Parameters:

• ctx – This is the target-dependent context that is created by get_context

• options – Compiling options passed in by the user

Returns:

The passes to be ran

context get_context() const

Construct a context for the target.

Returns:

The context to be used during compilation and execution.

supported_segments target_is_supported(T&, const_module_ref mod, support_metric metric) const

Get the ranges of instructions that are supported on a target.

Parameters:

• module – Module to check for supported instructions

• metric – Used to define how the quality of the support should be measured

Returns:

the supported segments of the graph

argument copy_to(const argument &arg) const

copy an argument to the current target.

Parameters:

arg – Input argument to be copied to the target

Returns:

Argument in the target.

argument copy_from(const argument &arg) const

copy an argument from the current target.

Parameters:

arg – Input argument to be copied from the target

Returns:

Argument in the host.

argument allocate(const shape &s) const

Allocate an argument based on the input shape.

Parameters:

s – Shape of the argument to be allocated in the target

Returns:

Allocated argument in the target.
