* 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_.

* rtems/score/cpu.h: Removed. * Makefile.am: Reflect changes above.

* Per PR94, all rtems/score/CPUtypes.h are named rtems/score/types.h. * rtems/score/cpu.h: Account for name change.

* configure.ac: AC_INIT(package,_RTEMS_VERSION,_RTEMS_BUGS). AM_INIT_AUTOMAKE([no-define foreign 1.6]). * Makefile.am: Remove AUTOMAKE_OPTIONS.

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.

* 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!

2000-07-07Picking up changes missed in previous commit. These changesJoel Sherrill1-8/+3
were needed to move exception processing to score/cpu.
2000-07-07Moved old_exception_processing and new_exception_processing directoriesJoel Sherrill1-2/+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.

<corsepiu@faw.uni-ulm.de>: The patch below provides * automake support for score/cpu/powerpc * The hack to propagate values from *.cfg to automake configuration * A fix for librdbg/powerpc/mcp750/Makefile.am (Was completely corrupted before) * Fixes some files which apparently where missing in rtems-rc-19991123-rc-2.diff * some minor configuration related patches To apply: rm -rf ./c/src/exec/score/cpu/powerpc/wrap patch -p1 < rtems-rc-19991123-rc-3.diff Attention: c/src/exec/score/cpu/[configure.in|aclocal.m4|configure] should be removed after applying the patch.
1999-12-02Merged of mcp750 and mvme2307 BSP by Eric Valette <valette@crf.canon.fr>.Joel Sherrill4-0/+1500
As part of this effort, the mpc750 libcpu code is now shared with the ppc6xx.
