* Makefile.am: Use .$(OBJEXT) instead of .o.
2002-07-212002-07-21 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Ralf Corsepius2-2/+6
* Makefile.am: Fix oversights in previous patch.

* rtems.S: Remove. * Makefile.am: Reflect having removed rtems.S. Use AM_CPPFLAGS instead of INCLUDES (Latest automake standard).

* cpu.c: Per PR211 fix saving/restoring floating point context. The fpsave and fprestore routines are only used in a executing context which _is_ fp and hence has the FPU enabled. The current behavior required the FPU always to be on which is very dangerous if lazy context switching is used. [Joel Note: Some ports explicitly enabled the FPU in the FP save and restore routines to avoid this.] The patch also makes sure (on powerpc only) that the FPU is disabled for integer tasks. Note that this is crucial if deferred fp context switching is used. Otherwise, fp context corruption may go undetected! Also note that even tasks which merely push/pop FP registers to/from the stack without modifying them still MUST be FP tasks - otherwise (if lazy FP context switching is used), FP register corruption (of other, FP, tasks may occur)! Furthermore, (on PPC) by default, lazy FP context save/restore is _disabled_.

* cpu.c: Include <rtems/powerpc/cache.h>.

* rtems/score/cpu.h: Removed. * Makefile.am: Reflect changes above.
2002-04-032001-04-03 Joel Sherrill <joel@OARcorp.com>Joel Sherrill4-2/+12
* Per PR94, all rtems/score/CPUtypes.h are named rtems/score/types.h. * rtems/score/cpu.h: Account for name change.
2002-03-282002-03-27 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill6-6/+18
* configure.ac: AC_INIT(package,_RTEMS_VERSION,_RTEMS_BUGS). AM_INIT_AUTOMAKE([no-define foreign 1.6]). * Makefile.am: Remove AUTOMAKE_OPTIONS.
2001-11-282001-11-28 Joel Sherrill <joel@OARcorp.com>,Joel Sherrill10-21/+68
This was tracked as PR91. * rtems/score/cpu.h: Added CPU_PROVIDES_ISR_IS_IN_PROGRESS macro which is used to specify if the port uses the standard macro for this (FALSE). A TRUE setting indicates the port provides its own implementation. * rtems/score/c_isr.inl: Deleted and contents merged into cpu.c. * cpu.c: Received contents of c_isr.inl. * Makefile.am: Deleted reference to c_isr.inl.
2001-11-272001-11-26 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill4-0/+16
* .cvsignore: Add aclocal.m4, autom4te.*, config.*, configure.
2001-11-212001-11-21 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill4-2/+14
* Makefile.am: Preinstall c_isr.inl (HACK). * ChangeLog: New file.

* new_exception_processing/cpu_asm.S: Support double or single precision context switches. Note that doing a single precision context save/restore on a double precision PowerPC machine does not only result in rounding errors but also screws up the FPSCR register!

This modification is part of the submitted modifications necessary to support the IBM PPC405 family. This submission was reviewed by Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did not negatively impact the ppc403 BSPs. The submission and tracking process was captured as PR50. * ppc403/console/console405.c ppc403/tty_drv/.cvsignore, ppc403/tty_drv/Makefile.am, ppc403/tty_drv/tty_drv.c, ppc403/tty_drv/tty_drv.h: New files. * Makefile.am, README, configure.ac, old_exception_processing/cpu.c, old_exception_processing/cpu.h, ppc403/Makefile.am, ppc403/clock/clock.c, ppc403/console/Makefile.am, ppc403/console/console.c, ppc403/ictrl/ictrl.c, ppc403/ictrl/ictrl.h, ppc403/timer/timer.c: Modified.

2000-07-07Picking up changes missed in previous commit. These changesJoel Sherrill2-11/+7
were needed to move exception processing to score/cpu.
2000-07-07Moved old_exception_processing and new_exception_processing directoriesJoel Sherrill2-4/+0
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.

2000-06-12Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine GauthierJoel Sherrill3-2/+16
<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
