Misc. support tools for RTEMS workspaces.
|
|
||||||
More will be added later as they are converted from Teamware
|
|
||||||
to CVS.
|
|
||||||
|
|
||||||
install-if-change
|
|
||||||
Smart install script that also can append suffixes as it
|
|
||||||
installs (suffixes used for debug and profile variants).
|
|
||||||
Requires bash or ksh.
|
|
||||||
|
|
||||||
rcs-clean
|
|
||||||
deletes all files from the current directory that can be
|
|
||||||
re-created from RCS. Careful to not delete locked files.
|
|
||||||
May be used by 'gmake clobber'
|
|
||||||
|
|
||||||
lock-directory
|
|
||||||
unlock-directory
|
|
||||||
traverse a directory structure making it unwritable.
|
|
||||||
Useful to keep people from accidentally overwriting
|
|
||||||
"released" trees if they get confused about which
|
|
||||||
module they have loaded.
|
|
||||||
|
|
||||||
rtems-glom
|
|
||||||
glom together all the rtems libraries in order to simplify
|
|
||||||
the link line used by applications.
|
|
||||||
Produces rtems.rel.
|
|
||||||
Not used by the RTEMS src tree at all.
|
|
||||||
Strictly optional.

Overview of newlib support (newlib is from CYGNUS)
|
|
||||||
Each task can have its own libc state including:
|
|
||||||
open stdio files
|
|
||||||
strtok
|
|
||||||
multi precision arithmetic state
|
|
||||||
etc.
|
|
||||||
|
|
||||||
This is implemented by a reentrancy data structure for each task.
|
|
||||||
|
|
||||||
When a task is "started" (in RTEMS sense) the reentrancy structure
|
|
||||||
is allocated. Its address is stored in notepad[NOTEPAD_LAST].
|
|
||||||
|
|
||||||
When task is switched to, the value of global variable _impure_ptr
|
|
||||||
is changed to the value of the new tasks reentrancy structure.
|
|
||||||
|
|
||||||
When a task is deleted
|
|
||||||
atexit() processing (for that task) happens
|
|
||||||
task's stdio buffers are flushed
|
|
||||||
|
|
||||||
When exit(3) is called
|
|
||||||
calling task's atexit processing done
|
|
||||||
global libc state atexit processing done
|
|
||||||
(this will include any atexit routines installed by drivers)
|
|
||||||
executive is shutdown
|
|
||||||
causes a context switch back to bsp land
|
|
||||||
|
|
||||||
|
|
||||||
NOTE:
|
|
||||||
libc extension are installed by bsp_libc_init()
|
|
||||||
iff we are using clock interrupts.
|
|
||||||
This hack is necessary to allow the tmtests to avoid
|
|
||||||
timing the extensions.

* These routines provide general purpose error reporting.
|
|
||||||
* rtems_error reports an error to stderr and allows use of
|
|
||||||
* printf style formatting. A newline is appended to all messages.
|
|
||||||
*
|
|
||||||
* error_flag can be specified as any of the following:
|
|
||||||
*
|
|
||||||
* RTEMS_ERROR_ERRNO -- include errno text in output
|
|
||||||
* RTEMS_ERROR_PANIC -- halts local system after output
|
|
||||||
* RTEMS_ERROR_ABORT -- abort after output
|
|
||||||
*
|
|
||||||
* It can also include a rtems_status value which can be OR'd
|
|
||||||
* with the above flags. *
|
|
||||||
*
|
|
||||||
* EXAMPLE
|
|

* #include <rtems.h>
|

* #include <rtems/error.h>
|
|
||||||
* rtems_error(0, "stray interrupt %d", intr);

* Created: 94/12/10

*
|
|
||||||
* Description:
|
|
||||||
* Called from exit() after it does atexit() processing and stdio fflush's
|
|
||||||
*
|
|
||||||
* called from bottom of exit() to really delete the task.
|
|
||||||
* If we are using reentrant libc, then let the delete extension
|
|

* do all the work, otherwise if a shutdown is in progress,
|
|
||||||
* then just do it.
|

||||||
*
|
|
||||||
* Parameters:
|
|
||||||
* exit status
