Hello,
I plan to move content from confdefs.h to separate header files for
configuration groups. What should confdefs.h do if CONFIGURE_INIT is not
defined?
Should we do the consistency checks for example if CONFIGURE_INIT is not
defined, e.g.
#if defined(CONFIGURE_UNLIMITED_OBJECTS)
#if !defined(CONFIGURE_UNIFIED_WORK_AREAS) && \
!defined(CONFIGURE_EXECUTIVE_RAM_SIZE) && \
!defined(CONFIGURE_MEMORY_OVERHEAD)
#error "CONFIGURE_UNLIMITED_OBJECTS requires a unified work area,
an executive RAM size, or a defined workspace memory overhead"
#endif
vs.
#ifdef CONFIGURE_INIT
#if defined(CONFIGURE_UNLIMITED_OBJECTS)
#if !defined(CONFIGURE_UNIFIED_WORK_AREAS) && \
!defined(CONFIGURE_EXECUTIVE_RAM_SIZE) && \
!defined(CONFIGURE_MEMORY_OVERHEAD)
#error "CONFIGURE_UNLIMITED_OBJECTS requires a unified work area,
an executive RAM size, or a defined workspace memory overhead"
#endif
What about includes, e.g.
#ifdef CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#include <rtems/clockdrv.h>
#ifdef CONFIGURE_INIT
RTEMS_SYSINIT_ITEM(
_Clock_Initialize,
RTEMS_SYSINIT_DEVICE_DRIVERS,
RTEMS_SYSINIT_ORDER_THIRD
);
#endif
#endif
vs.
#ifdef CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#ifdef CONFIGURE_INIT
#include <rtems/clockdrv.h>
RTEMS_SYSINIT_ITEM(
_Clock_Initialize,
RTEMS_SYSINIT_DEVICE_DRIVERS,
RTEMS_SYSINIT_ORDER_THIRD
);
#endif
#endif
?
My approach would be to place all the define evaluations into a #ifdef
CONFIGURE_INIT guard, so that #include <rtems/confdefs.h> provides
nothing to the C compiler if CONFIGURE_INIT is not defined.
