Exceptions during system initialization work only on targets which do not need
a registration of exception frames during the global construction. In
particular, targets which use the DWARF2 unwinder cannot use exceptions during
system initialization.
For architectures with relatively large minimum stack sizes, this test
breaks during compilation due to a static check. The init task stack
size should not need to be set for this test.
When I use the 'shell' from the fileio sample with the command below:
env QEMU_AUDIO_DRV="none" \
qemu-system-arm -no-reboot -net none -nographic -M realview-pbx-a9 \
-m 256M \
-kernel build/arm/realview_pbx_a9_qemu/testsuites/samples/fileio.exe
The executable crashes with an "BLOWN STACK!!!" as soon as I try to login
as 'root' with password. (The logins without password work fine.)
Increasing the stack size of the affected thread a bit solves the issue.
Hence, I suggest this patch.
My config.ini was
[arm/realview_pbx_a9_qemu]
RTEMS_DEBUG = True
RTEMS_NETWORKING = True
RTEMS_POSIX_API = True
RTEMS_SMP = True

Rename this header file to later move <t.h> to <rtems/test.h>. The main
feature provided by <rtems/test-info.h> is the output of standard test
information which is consumed by the RTEMS Tester.
Update #3199.
Allocate new thread queue heads during objects information extend. This
removes an error case and the last dependency on the workspace in
_Thread_Initialize().
Update #3835.
This option silences warning with automake-1.16.1 allowing us to
upgrade to that version.
This change has been tested with automake-1.12.6 and automake-1.16.1.
It seems version 1.16.1 configures slower than 1.12.6 for the same
source and BSP. The newer versions is 6 second slower.
Close#3387.
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.
