Macro Definition Documentation

◆ PORT_ARCH_SIZEOF_DATA_PTR

#define PORT_ARCH_SIZEOF_DATA_PTR 4

Definition at line 41 of file chtypes.h.

◆ PORT_ARCH_SIZEOF_CODE_PTR

#define PORT_ARCH_SIZEOF_CODE_PTR 4

Definition at line 42 of file chtypes.h.

◆ PORT_ARCH_REGISTERS_WIDTH

#define PORT_ARCH_REGISTERS_WIDTH 32

Definition at line 43 of file chtypes.h.

◆ PORT_ARCH_REVERSE_ORDER

#define PORT_ARCH_REVERSE_ORDER 1

Definition at line 44 of file chtypes.h.

◆ PORT_DOES_NOT_PROVIDE_TYPES

#define PORT_DOES_NOT_PROVIDE_TYPES

This port does not define OS-related types.

Definition at line 78 of file chtypes.h.

◆ ROMCONST

#define ROMCONST CC_ROMCONST

ROM constant modifier.

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

Definition at line 84 of file chtypes.h.

◆ NOINLINE

#define NOINLINE CC_NO_INLINE

Makes functions not inlineable.

Note: If the compiler does not support such attribute then some time-dependent services could be degraded.

Definition at line 91 of file chtypes.h.

Referenced by chTMChainMeasurementToX(), chTMStartMeasurementX(), chTMStopMeasurementX(), and trace_next().

◆ ALIGNED_VAR

#define ALIGNED_VAR ( n )

Value:

CC_ALIGN_DATA(n)

CC_ALIGN_DATA

#define CC_ALIGN_DATA(n)

Enforces alignment of the variable declared afterward.

Definition ccportab.h:80

Memory alignment enforcement for variables.

Definition at line 96 of file chtypes.h.

◆ SIZEOF_PTR

#define SIZEOF_PTR PORT_ARCH_SIZEOF_DATA_PTR

Size of a pointer.

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

Definition at line 103 of file chtypes.h.

Typedef Documentation

◆ port_rtcnt_t

typedef uint32_t port_rtcnt_t

Realtime counter.

Definition at line 54 of file chtypes.h.

◆ port_rttime_t

typedef uint64_t port_rttime_t

Realtime accumulator.

Definition at line 59 of file chtypes.h.

◆ port_syssts_t

typedef uint32_t port_syssts_t

System status word.

Definition at line 64 of file chtypes.h.

◆ port_stkalign_t

typedef uint64_t port_stkalign_t

Type of stack and memory alignment enforcement.

Note: In this architecture the stack alignment is enforced to 64 bits, 32 bits alignment is supported by hardware but deprecated by ARM, the implementation choice is to not offer the option.
