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.

These BSPs used shared/startup/linkcmds.base and had to be modified
as a set.

This bsp-specs added many libraries which it should not have. It
also added the non-standard -qjava option which if actually used
will have to be addressed by adding linker options on the GCC
command line.

* bsp_specs: Move -e start from *link to *startfile to avoid warning
for undefined entry symbol when linking relocatables with binutils
2.19.

* bsp_specs: Remove qrtems_debug.
|
| |
|
|
|
| |
* bsp_specs: Remove -D__embedded__ -Asystem(embedded) from cpp.
Remove cpp, old_cpp (now unused).
|

* bsp_specs: Added support for -nostdlibs.
|
| |
|
|
|
| |
* bsp_specs: Replace -lrtemsall with -lrtemsbsp -lrtemscpu,
replace -lrtemsall_g with -lrtemsbsp_g -lrtemscpu_g.

<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart
<Darlene.Stewart@nrc.ca> to add support for a number of very
significant things:
+ BSPs for many variations on the Motorola MBX8xx board series
+ Cache Manager including initial support for m68040
and PowerPC
+ Rework of mpc8xx libcpu code so all mpc8xx CPUs now use
same code base.
+ Rework of eth_comm BSP to utiltize above.
John reports this works on the 821 and 860

for the gen68360 that let it work with ELF and C++ exceptions. This
was used as the basis for changes to EVERY m68k bsp_specs and linkcmds.
Before this modification is over, the layout of the starting stack,
heap, and workspace will likely be modified for every m68k BSP. Then
they will all be very similar.

Ralf Corsepius <corsepiu@faw.uni-ulm.de> which converted many
Makefile.in's to Makefile.am's. This added a lot of files.

to address m68k-rtemself for the MVME167.
Here is the rtems patch I promissed you a long time ago to enable ELF
with m68k. The target name I selected is m68k-rtemself. It preserves the
m68k-rtems COFF target, and is parterned after the other ELF/COFF dual
targets.
The mvme167.cfg file causes the -qelf flag to be used during compilation
if the name of the compiler contains rtemself. This flag is used in the
bsp_specs file to select the elflinkcmds file rather than the linkcmds
file. The former is for ELF, the latter for COFF.
Some patches are required to the mc68040 FPSP code. Some of the
assembler files contain instructions that were rejected by the
m68k-rtemself-as assembler. This is a minor bug in the m68k ELF
assembler, I think.
