Port Types

Collaboration diagram for Port Types:

Detailed Description

The types defined in this file may change depending on the target architecture. You may also try to optimize the size of the various types in order to privilege size or performance, be careful in doing so.

Macros
#define	ROMCONST   const
	ROM constant modifier. More...
#define	NOINLINE   __attribute__((noinline))
	Makes functions not inlineable. More...
#define	PORT_THD_FUNCTION(tname, arg)   void tname(void *arg)
	Optimized thread function declaration macro. More...
#define	PACKED_VAR   __attribute__((packed))
	Packed variable specifier. More...
#define	ALIGNED_VAR(n)   __attribute__((aligned(n)))
	Memory alignment enforcement for variables. More...
#define	SIZEOF_PTR   4
	Size of a pointer. More...
#define	REVERSE_ORDER   1

Macro Definition Documentation

ROMCONST

#define ROMCONST   const

ROM constant modifier.

Note

It is set to use the "const" keyword in this port.

Definition at line 63 of file chtypes.h.

NOINLINE

#define NOINLINE   __attribute__((noinline))

Makes functions not inlineable.

Note

If the compiler does not support such attribute then the realtime counter precision could be degraded.

Definition at line 70 of file chtypes.h.

PORT_THD_FUNCTION

#define PORT_THD_FUNCTION	(		tname,
			arg
	)		void tname(void *arg)

Optimized thread function declaration macro.

Definition at line 75 of file chtypes.h.

PACKED_VAR

#define PACKED_VAR   __attribute__((packed))

Packed variable specifier.

Definition at line 80 of file chtypes.h.

ALIGNED_VAR

#define ALIGNED_VAR

(

n

)

__attribute__((aligned(n)))

Memory alignment enforcement for variables.

Definition at line 85 of file chtypes.h.

SIZEOF_PTR

#define SIZEOF_PTR   4

Size of a pointer.

Note

To be used where the sizeof operator cannot be used, preprocessor expressions for example.

Definition at line 92 of file chtypes.h.

REVERSE_ORDER

#define REVERSE_ORDER   1

True if alignment is low-high in current architecture.

Definition at line 97 of file chtypes.h.
