Macro Definition Documentation

RTEMS_RTL_TRACE

#define RTEMS_RTL_TRACE   1

Set to 1 to build trace support in to the RTL code.

RTEMS_RTL_TRACE_ALL

#define RTEMS_RTL_TRACE_ALL

Value:

                                                                 (0xffffffffUL & ~(RTEMS_RTL_TRACE_CACHE | \

RTEMS_RTL_TRACE_DETAIL

#define RTEMS_RTL_TRACE_DETAIL   (1UL << 0)

List of tracing bits for the various parts of the link editor.

Typedef Documentation

rtems_rtl_trace_mask

typedef uint32_t rtems_rtl_trace_mask

The type of the mask.

Function Documentation

rtems_rtl_trace()

bool rtems_rtl_trace

(

rtems_rtl_trace_mask

mask

)

Call to check if this part is bring traced. If RTEMS_RTL_TRACE is defined to 0 the code is dead code elminiated when built with -Os, -O2, or higher.

Parameters

mask	The part of the API to trace.

Return values

true	Tracing is active for the mask.
false	Do not trace.

rtems_rtl_trace_clear_mask()

rtems_rtl_trace_mask rtems_rtl_trace_clear_mask

(

rtems_rtl_trace_mask

mask

)

Clear the mask.

Parameters

mask	The mask bits to clear.

Returns

The previous mask.

rtems_rtl_trace_set_mask()

rtems_rtl_trace_mask rtems_rtl_trace_set_mask

(

rtems_rtl_trace_mask

mask

)

Set the mask.

Parameters

mask	The mask bits to set.

Returns

The previous mask.

rtems_rtl_trace_shell_command()

int rtems_rtl_trace_shell_command	(	const rtems_printer *	printer,
		int	argc,
		char *	argv[]
	)

Add shell trace shell command.
