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.
The link time wrap of printf leads to unresolved symbols in the loadable
modules. This resulted in infinite loops and test timeouts. Use
rtems_printf() for output.
Update #3199.
- Remove the macro defines and the need for tmacro.h by remapping the
symbols using ld's wrap option.
- Remove FLUSH_OUTPUT, it was empty.
- Move rtems_test_exit to libmisc/testsupport as a function.
Update #3199.
In canonical mode, input is made available line by line. We must stop
the canonical buffer filling upon reception of an end-of-line character.
Close#3218.
- Remove the printf support leaving the direct printk support configured
with TESTS_USE_PRINTK and all other output goes via a buffered vsniprintf
call to printk.
- Control the test's single init for functions and global data with
TEST_INIT and not CONFIGURE_INIT. They are now separate.
Updates #3170.
Remove obsolete support for OFILL, OFDEL, NLDLY, CRDLY, BSDLY, VTDLY,
and FFDLY which is not present on FreeBSD and not implemented in Linux.
Update #2833.
Do not use the processor count to determine if SMP is enabled. Instead
use a dedicated configuration option. Enable SMP by default in SMP
configurations.
Add CONFIGURE_DISABLE_SMP_CONFIGURATION to all test which would fail
otherwise.
Update #3001.
Enable the SMP configuration by default in case SMP is enabled. Add
configuration option CONFIGURE_DISABLE_SMP_CONFIGURATION to disable it
explicitly.
Add CONFIGURE_DISABLE_SMP_CONFIGURATION to all test which would fail
otherwise.
Update #3001.
- Add a top level test configuration file for test states that are common
to all BSPs. This saves adding a test configuration (tcfg) file for
every BSP.
- Add the test states 'user-input' and 'benchmark'. This
lets 'rtems-test' stop the test rather than waiting for a timeout or
letting a benchmark run without the user asking for it to run.
- Implement rtems-test-check in Python to make it faster. The shell script
had grown to a point it was noticably slowing the build down.
- Fix the configure.ac and Makefile.am files for a number of the
test directories. The files are difficiult to keep in sync with the
number of tests and mistakes can happen such as tests being left
out of the build. The test fsrofs01 is an example. Also a there was
a mix of SUBDIRS and _SUBDIRS being used and only _SUBDIRS should be
used.
- Fix the test fsrofs01 so it compiles.
Closes#2963.
The ARM C++ exception ABI uses an address ordered index table to
locate the correct frame data and this requires the EXIDX sections are
loaded in the order the order the matching text is loaded.
The EXIDX sections set the SHF_LINK_ORDER flag and link field. This patch
adds support to load those flagged sections in the linked-to section
order.
Updates #2955.
Closes#2959
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.
Close#2897.
