Update #3706.
|
|
Statically allocate the objects information together with the initial
set of objects either via <rtems/confdefs.h>. Provide default object
informations with zero objects via librtemscpu.a. This greatly
simplifies the workspace size estimate. RTEMS applications which do not
use the unlimited objects option are easier to debug since all objects
reside now in statically allocated objects of the right types.
Close #3621.

Update #3598.

A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.
Update #3254.

Make the id the first parameter since usual callers get the object
identifier as the first parameter themself.
|

Extension create and delete is protected by the object allocator lock.

Move implementation specific parts of object.h and object.inl into new
header file objectimpl.h. The object.h contains now only the
application visible API.
|
|
Move implementation specific parts of extension.h and extension.inl into
new header file extensionimpl.h. The extension.h contains now only the
application visible API.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

the inline implementation. The impetus for this was twofold. First,
it is incorrect to have static inline prototypes when using the macro
implementation. Second, this reduced the number of lines in the include
files seen by rtems.h by about 2000 lines.
Next we restricted visibility for the inline routines to inside the
executive itself EXCEPT for a handful of objects. This reduced the
number of include files included by rtems.h by 40 files and reduced
the lines in the include files seen by rtems.h by about 6000 lines.
In total, these reduced the compile time of the entire RTEMS tree by 20%.
This results in about 8 minutes savings on the SparcStation 10 morgana.
