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.
Adding modified FreeBSD headers to synchronize RTEMS termios with
FreeBSD. Modify termios to support dedicated input and output baud for
termios structure. Updated BSPs to use dedicated input and output baud
in termios structure. Updated tools to use dedicated input and output
baud in termios structure. Updated termios testsuites to use dedicated
input and output baud in termios structure.

This commit deletes all RTEMS ChangeLog files. These files have been abandoned
since converting to git version control. The historical data may be recovered
by checking out any commit before this one. Most of the contents of these
ChangeLog files can also be found in the git log.
Two external ChangeLog files, ChangeLog.slac and ChangeLog.zlib, remain.
These modifications were required by hand after running the script.
In some cases, the file names did not match patterns. In others,
the format of the file did not match any common patterns.
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.
* linkcmds.c, linkcmds.h, memory.c, memory.h, sample.ptf: New files.
* bridges.c: corrected detection of bridged connections
* clocks.c: removed a printf
* linkcmds.[ch] new files, added output of linker script
* Makefile.am: added new files
* memory.[ch]: new files, detection of memory in SOPC configuration
* nios2gen.c: updated command line parsing and output control
* output.[ch]: improved output of BSP header file
* ptf.[ch]: added ptf_dump_ptf_item and small fixes
* sample.ptf: new file, sample configuration for nios2gen
* README: updated
* nios2gen.c: Added some very basic support for --help and --version
options along with output that is roughly in GNU format. This is
required by help2man. help2man expects this all to be written to
stdout instead of stderr so this was changed as well.
* ChangeLog: New file.
* configure.ac: New port to Altera NIOS II.
* nios2/.cvsignore, nios2/Makefile.am, nios2/README, nios2/bridges.c,
nios2/bridges.h, nios2/clocks.c, nios2/clocks.h, nios2/configure.ac,
nios2/devices.c, nios2/devices.h, nios2/nios2gen.c, nios2/output.c,
nios2/output.h, nios2/ptf.c, nios2/ptf.h: New files.
