* custom/shsim.cfg: New file.
* custom/Makefile.am: Modified to reflect addition of shsim.cfg.
The shsim is for the SH simulator in gdb. It should be able
to be used with multiple SH CPU models. This will require
adding BSP variants.
* custom/pc386.cfg: make-exe rule would write into
$(PROJECT_RELEASE) area. This is not cool because it $(PROJECT_RELEASE)
is generally not writeable after the BSP is installed and you do not
want every application installed there by default. Reported by
Eric Norum <eric.norum@usask.ca>.
* custom/Makefile.am: Modified to reflect addition of files.
* custom/erc32.cfg: Modified to support addition of no-FP ERC32 variant.
* custom/erc32nfp.cfg, custom/leon1.cfg, custom/leon2.cfg: New file.
* custom/p4600.cfg, custom/p4650.cfg: Commented out RTEMS_CPU
definition since this information can be picked up from
autoconf generated files. These BSPs are shared by the
mips and mips64orion "ports."
* custom/mbx860_005b.cfg (make-target-options): Add lines to
define PRINTK_MINOR SMC1_MINOR and PRINTK_IO_MODE. The settings
may be incorrect but the BSP now compiles.
* make/custom/pck6.cfg: New file
* make/custom/pc486.cfg: Use -m486
* make/custom/pc586.cfg: Use -mpentium
* make/custom/pc686.cfg: Use -mmpentiumpro
* make/custom/i386ex.cfg: Use -msoft-float
* mbx8xx.cfg: Support for shared printk and no termios.

* mbx8xx.cfg: Support added for dejagnu test harness.
that does the following:
Changes:
Remove $(SED) and $(CP) from make/custom/*.cfg
Motivation:
* autoconf and automake presuppose sed and cp to be present.
* make/host.cfg.in already contains SED = sed hard-coded into it for
a long time.
* Elimination of make-variables
* Eliminate make/*.cfg files or at least reduce their complexity :)

of Canon CRF - Communication Dept. This port includes a
basic BSP that is sufficient to link hello world.
a BSP (c4xsim) supporting the simulator included with gdb. This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.
An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU. This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.
that is yet another multilib-related structual cleanup patch:
Changes:
* Make RTEMS_TEST_NO_PAUSE a tests/ subpackage specific option.
- Remove RTEMS_TEST_NO_PAUSE from custom/*.cfg, targopts.h and
cpuopts.h.
- Add autoconf macros RTEMS_*_RTEMS_TEST_NO_PAUSE
(aclocal/rtems-test-no-pause.m4).
- Add RTEMS_*_RTEMS_TEST_NO_PAUSE support to sptests/configure.ins
and tmtests/configure.in. These are the only subdirectories which
currently apply RTEMS_TEST_NO_PAUSE.
- Add autoconf-DEFS support to all test subpackages' configure.ins
below tests/. I.e. AC_DEFINES now get explicitly propagated as
preprocessor defines into Makefiles, cf. AM_CPPFLAGS in
tests/*/*.am, instead of using a global config-files.
- Remove NDEBUG from custom/*.cfg.
* AC_DEFINE POSIX_API, ITRON_API and MULTIPROCESSING in
exec/configure.in, only.
- All other sources now should relay on the values from cpuopts.h
and should not define them themselves.
- Several related changes to many configure.ins
* Bug-fixes to RTEMS_*_RTEMS_DEBUG macros (Actually workarounds to
quoting bugs in autoconf).
Notes:
* This patch is rather immature and only tested for a small subset
of BSPs (requires the tests to be enabled and therefore takes an
tremendous amount of disc space and time.)
* The patches to *cfg were generated by a script. Expect file
formating changes :)
that is yet another multilib-related structual cleanup patch:
Changes:
* Make RTEMS_DEBUG a global per-cpu configuration option
* Remove RTEMS_DEBUG from targopts.h
* Add a global --enable-rtems-debug option disabled by default.
* Add RTEMS_DEBUG to cpuopts.h
* Remove all references to RTEMS_DEBUG from custom/*.cfg
Notes:
* RTEMS_DEBUG is set in c/src/exec/configure.in only
(RTEMS_CHECK_RTEMS_DEBUG) and should be defined in cpuopts.h only.
BSPs should not redefine it, but use the value being provided by
cpuopts.h.
=> With multilibs, users have to choose: Either enable RTEMS_DEBUG
for all BSPs and CPU_MODELs of a cpu or not.
* Only few BSPs had RTEMS_DEBUG enabled, therefore I set the default
to disabled.
* This patch influences the per-BSP building scheme. Existing BSPs
which set RTEMS_DEBUG in their make-target-options rule might have
problems at runtime.
routines and structures that require CPU model specific information
are now in libcpu. This primarily required moving erc32 specific
information from score/cpu files to libcpu/sparc and the erc32 BSP.
routines and structures that require CPU model specific information
are now in libcpu. This required significant rework of the
score/cpu header files and the creation of multiple header files
and subdirectories in libcpu/i960.
that decouples exec/ for the sh, m68k and i960 from targopts.h.
NOTE: The change to system.h is a hack to enable cpuopts.h
for some targets, but keep using targopts.h for others - I know it
does *not* work for sparc, mips, i386 and ppc. This will have
to be addressed as work continues on multilibing.
