2000-08-01ARMulator BSP now runs with gdb 5.0.Joel Sherrill2-1/+36
2000-07-31Closer to linking. h8300-rtems-ld now core dumps.Joel Sherrill3-16/+33
2000-07-31New bsp for simulator in gdb. Does not work yet.Joel Sherrill25-0/+1290
2000-07-27Minor problems addressed with the merger and with the arm_bare_bsp.Joel Sherrill18-194/+75
That BSP now has a stub clock driver so the tests can link even if they won't execute. A handful of Makefiles had to be updated and we had to account for printk.c being a shared file now.
2000-07-27Port of RTEMS to the ARM processor family by Eric ValetteJoel Sherrill59-0/+4680
<valette@crf.canon.fr> and Emmanuel Raguet <raguet@crf.canon.fr> of Canon CRF - Communication Dept. This port includes a basic BSP that is sufficient to link hello world.
2000-07-26Patch from Charles-Antoine Gauthier <charles.gauthier@nrc.ca> thatJoel Sherrill3-74/+78
removes warnings from the network.c file and has slight additions to the configuration file to support Java.
2000-07-26Added ifdef on C4x to avoid invalid address alignment checks since thereJoel Sherrill3-0/+28
is no such thing on the C4x.
2000-07-26Port of RTEMS to the Texas Instruments C3x/C4x DSP families includingJoel Sherrill14-8/+51
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 removes an unnecessary inclusion of @RTEMS_BSP@.cfg.
2000-07-25Forgot to remove these when code moved.Joel Sherrill16-4955/+0

2000-07-24Patch from Eric Valette <valette@crf.canon.fr> with debuggingJoel Sherrill1-7/+15
by Till Straumann <strauman@SLAC.Stanford.EDU>. With this patch, the motorola_shared BSP should also support the MVME2303.
2000-07-17Make _ISR_Dispatch global.Joel Sherrill1-0/+1
2000-07-17Update from Philip Quaife <rtemsdev@qs.co.nz> that was hand-merged.Joel Sherrill2-34/+75
This update addresses the following: + the ISR enable/disable/flash macros now work with old gcc versions. + the UI CCR bits are now masked since other example code did so + _ISR_Dispatch disables interrupts during call setup Together these removed the instabilities he was seeing.

2000-07-13Patch rtems-rc-20000713-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill71-113/+83
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 :)
2000-07-12Patch rtems-rc-20000712-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1-0/+2
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.

2000-07-11New file.Joel Sherrill1-0/+2
2000-07-11Reworked score/cpu/sparc so it can be safely compiled multilib. AllJoel Sherrill18-668/+73
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.
2000-07-11Added Hitachi H8/300 to the list of CPUs that should be OK withJoel Sherrill1-0/+1
using cpuopts.h and not targopts.h.

2000-07-11Reworked score/cpu/i960 so it can be safely compiled multilib. AllJoel Sherrill37-602/+910
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.
2000-07-11Patch rtems-rc-20000711-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill7-6/+16
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.
2000-07-10Patch rtems-rc-20000709-1.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill16-56/+143
that addresses aspects of the targopts.h multilib related issues. Changes: * Move targopts.h to libbsp/include, because the current targopts.h actually is a per-BSP-header and therefore can not stay below exec/. * Introduce an autoheader generated header file (exec/score/include/rtems/score/cpuopts.h), which shall take per-cpu configuration options only. * Move all autoconf-detectable/configure specified per-cpu option-defines from targopts.h to cpuopts.h. * Add Makefiles to the libbsp/shared directory hierarchy. Notes: * The new per-bsp targopts.h in libbsp includes the per-cpu cpuopts.h. This way, the new targopts.h is kept backward compatible to the old targopts.h and existing BSPs which (carelessly) include targopts.h (i386, ppc) should be kept working when using the multilib-disabled configuration scheme. * cpuopts.h is not yet complete, because the per-BSP make-targopts rules from custom/<BSP>.cfg files can not be applied to files below exec/ when building multilibs. * All files below exec/ should not include targopts.h anymore, but should include cpuopts.h instead. However, eliminating inclusion of targopts.h currently triggers further structural / header file inclusion related issues, because several ports apply BSP or CPU_MODEL specific defines from targopts.h below exec/
2000-07-10Patch rtems-rc-20000708-1.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill16-45/+0
that is another small step toward multilibs: Changes: * Eliminate RTEMS_CHECK_CUSTOM_BSP from all configure.ins below exec/ * Add RTEMS_CHECK_CUSTOM_BSP to the multilib-disabled branch in RTEMS_ENV_RTEMSCPU to preserve the old per-BSP building scheme functional. Notes: * --enable-multilibs is still non-functional * This patch should not have any influence on the old building scheme (--disable-multilib should silently fall back to the old building scheme). * running ./bootstrap is required after applying the patch
2000-07-10Now links although linkcmds will not work on real hardware. But thenJoel Sherrill2-184/+244
again neither will unlinked executables. :)

2000-07-07Picking up changes missed in previous commit. These changesJoel Sherrill4-22/+14
were needed to move exception processing to score/cpu.
2000-07-07Moved old_exception_processing and new_exception_processing directoriesJoel Sherrill20-52/+50
from score/cpu to libcpu because the determination of which to use is based on RTEMS_CPU_MODEL. Thus it can not be determined based solely on multilib information.
