Passes

pass

struct migraphx::internal::pass

An interface for applying a transformation to the instructions in a program

Public Functions

std::string name() const: A unique name used to identify the pass.

void apply(module_pass_manager &mpm) const: Run the pass on the module.

void apply(module &m) const

void apply(program &p) const: Run the pass on the program.

dead_code_elimination

struct migraphx::internal::dead_code_elimination

Remove instructions where the output is not used.

Public Functions

inline std::string name() const

void apply(module &m) const

void apply(program &p) const

eliminate_common_subexpression

struct migraphx::internal::eliminate_common_subexpression

Remove identical instructions.

Public Functions

inline std::string name() const

void apply(module &p) const

eliminate_concat

struct migraphx::internal::eliminate_concat

Remove concat operators by having each operator can write to different chunk of memory.

Public Functions

inline std::string name() const

void apply(module &p) const

Public Members

concat_optimization concat_opt

eliminate_contiguous

struct migraphx::internal::eliminate_contiguous

Remove contiguous instructions by checking if the operator can use non-standard shapes.

Public Functions

inline std::string name() const

void apply(module &p) const

Public Members

std::string op_name

eliminate_identity

struct migraphx::internal::eliminate_identity

Remove identity instructions. Currently when used as the last pass, it will preserve the semantics of previous program state, therefore dead code elimination should not be used afterwards.

Public Functions

inline std::string name() const

void apply(module &p) const

eliminate_pad

struct migraphx::internal::eliminate_pad

Remove pads if they can be written as an attribute to another op (im2col, convolution, pooling)

Public Functions

inline std::string name() const

void apply(module &m) const

propagate_constant

struct migraphx::internal::propagate_constant

Replace instructions which take all literals with a literal of the computation.

Public Functions

inline std::string name() const

void apply(module &p) const

rewrite_batchnorm

struct migraphx::internal::rewrite_batchnorm

Rewrite batchnorm to a multiply and add.

Public Functions

inline std::string name() const

void apply(module &p) const

rewrite_rnn

struct migraphx::internal::rewrite_rnn

Rewrite rnn to gemm and add.

Public Functions

inline std::string name() const

void apply(module &prog) const

schedule

struct migraphx::internal::schedule

Schedule instructions for concurrent execution

Public Functions

inline std::string name() const

void apply(module &p) const

Public Members

schedule_model model = {}

bool enable = true

simplify_algebra

struct migraphx::internal::simplify_algebra

Simplify many algebraic instructions to more efficient versions.

Public Functions

inline std::string name() const

void apply(module &p) const

simplify_reshapes

struct migraphx::internal::simplify_reshapes

Eliminate redundant reshapes.

Public Functions

inline std::string name() const

void apply(module &p) const
