Detailed Description

Typedef Documentation

set_policy

template<typename Value , typename Policy >

using comppare::set_policy = typedef outspec<Value, Policy>

Alias for setting the error policy for a type.

Function Documentation

ClobberMemory()

void comppare::ClobberMemory ( )

inline

DoNotOptimize() [1/3]

template<typename T >

void comppare::DoNotOptimize ( T &&  value )

inline

Prevents the compiler from optimizing away the given value.

Template Parameters

T	The type of the value to protect from optimization.

Parameters

value

The value to protect from optimization.

This implementation is verbatim from Google Benchmark’s benchmark::DoNotOptimize(), licensed under Apache 2.0. No changes have been made.

DoNotOptimize() [2/3]

template<typename T >

void comppare::DoNotOptimize ( T &  value )

inline

Prevents the compiler from optimizing away the given value.

Template Parameters

T	The type of the value to protect from optimization.

Parameters

value

The value to protect from optimization.

This implementation is verbatim from Google Benchmark’s benchmark::DoNotOptimize(), licensed under Apache 2.0. No changes have been made.

DoNotOptimize() [3/3]

template<typename T >

void comppare::DoNotOptimize ( T const &  value )

inline

Prevents the compiler from optimizing away the given value.

Template Parameters

T	The type of the value to protect from optimization.

Parameters

value

The value to protect from optimization.

This implementation is verbatim from Google Benchmark’s benchmark::DoNotOptimize(), licensed under Apache 2.0. No changes have been made.

make_comppare()

template<typename... Outputs, typename... Inputs>

auto comppare::make_comppare

(

Inputs &&...

ins

)

Helper function to create a comppare object.

This function simplifies the creation of a comppare object by deducing the input types. It takes input arguments and returns an OutputContext object that can be used to add implementations and run comparisons. The output types must be specified explicitly as template parameters, while the input types are deduced from the function arguments. The function arguments are perfectly forwarded to instantiate the OutputContext object.

Template Parameters

Outputs	The types of the output specifications.
Inputs	The types of the input specifications – deduced from function arguments.

Parameters

ins	The input arguments.

Returns

typename InputContext<Inputs...>::OutputContext<Outputs...>
