Macro Definition Documentation

AXOM_DEVICE

#define AXOM_DEVICE

AXOM_HOST_DEVICE

#define AXOM_HOST_DEVICE

CUDA or HIP host/device macros for decorating functions/lambdas.

Note

These will expand to the corresponding CUDA/HIP decorations when compiled with -DAXOM_USE_CUDA or -DAXOM_USE_HIP

AXOM_HOST

#define AXOM_HOST

AXOM_LAMBDA

#define AXOM_LAMBDA   [=]

Convenience macro used for lambda capture by value.

Note

When CUDA or HIP is used, the macro always expands to a host/device lambda.

AXOM_DEVICE_LAMBDA

#define AXOM_DEVICE_LAMBDA   [=]

AXOM_HOST_LAMBDA

#define AXOM_HOST_LAMBDA   [=]

AXOM_STRINGIFY

#define AXOM_STRINGIFY

(

x

)

AXOM_DO_STRINGIFY(x)

AXOM_DO_STRINGIFY

#define AXOM_DO_STRINGIFY

(

x

)

#x

AXOM_PRAGMA

#define AXOM_PRAGMA

(

x

)

_Pragma(AXOM_STRINGIFY(x))

AXOM_SUPPRESS_HD_WARN

#define AXOM_SUPPRESS_HD_WARN

AXOM_CUDA_TEST

#define AXOM_CUDA_TEST	(		X,
			Y
	)		TEST(X, Y)

Convenience macro used for a gtest that uses cuda.

AXOM_UNUSED_PARAM

#define AXOM_UNUSED_PARAM

(

x

)

Macro used to silence compiler warnings in methods with unused arguments.

Note

The intent is to use this macro in the function signature. For example:

void my_function(int x, int AXOM_UNUSED_PARAM(y))
{
  // my implementation
}

AXOM_STATIC_ASSERT

#define AXOM_STATIC_ASSERT

(

cond

)

static_assert(cond, #cond)

AXOM_STATIC_ASSERT_MSG

#define AXOM_STATIC_ASSERT_MSG	(		cond,
			MSG
	)		static_assert(cond, MSG)

This macro wraps the compile time static_assert functionality so you don't have to provide a message.

AXOM_UNUSED_VAR

#define AXOM_UNUSED_VAR

(

_x

)

static_cast<void>(_x)

Macro used to silence compiler warnings about variables that are defined but not used.

Note

The intent is to use this macro for variables that are only used within compiler defines (e.g. in debug assertions). For example:

double myVar = ...
AXOM_UNUSED_VAR(myVar);
 
// code emits the following warning in release builds
// if extra warnings are enabled and this macro is not called
// warning: unused variable 'myVar' [-Wunused-variable]
 
SLIC_ASSERT(myVar > 0)

AXOM_DEBUG_PARAM

#define AXOM_DEBUG_PARAM

(

_x

)

_x

Macro used to silence compiler warnings about parameters that are only used when AXOM_DEBUG is defined.

Note

Default values are ok

void my_function(int x, int AXOM_DEBUG_PARAM(y))
{
  // my implementation
  SLIC_ASSERT(y > 0)
}

DISABLE_DEFAULT_CTOR

#define DISABLE_DEFAULT_CTOR

(

className

)

className() = delete

Macro to disable default constructor for the given class.

Note

This macro should only be used within the private section of a class, as indicated in the example below.

class Foo
{
public:
 
    // Public methods here
 
private:
   DISABLE_DEFAULT_CTOR(Foo);
};

DISABLE_COPY_AND_ASSIGNMENT

#define DISABLE_COPY_AND_ASSIGNMENT

(

className

)

Value:

  className(const className&) = delete;        \
  className& operator=(const className&) = delete

Macro to disable copy and assignment operations for the given class.

Note

This macro should only be used within the private section of a class, as indicated in the example below.

class Foo
{
public:
   Foo();
   ~Foo();
 
    // Other methods here
 
private:
   DISABLE_COPY_AND_ASSIGNMENT(Foo);
};

DISABLE_MOVE_AND_ASSIGNMENT

#define DISABLE_MOVE_AND_ASSIGNMENT

(

className

)

Value:

  className(className&&) = delete;             \
  className& operator=(className&&) = delete

Macro to disable move constructor and move assignment operations for the given class.

Note

This macro should only be used within the private section of a class, as indicated in the example below.

class Foo
{
public:
   Foo();
   ~Foo();
 
    // Other methods here
 
private:
   DISABLE_MOVE_AND_ASSIGNMENT(Foo);
};

AXOM_TYPED_TEST

#define AXOM_TYPED_TEST	(		CaseName,
			TestName
	)

Value:

  static_assert(sizeof(GTEST_STRINGIFY_(TestName)) > 1,                             \
                "test-name must not be empty");                                     \
