49        * cpu.c: Currently only the mpc8260 BSP supports interrupt nesting.
50        NOTE: These needs to be generalized as the patch is applied to other
51        BSPs.

64
65        * cpu.c: Per PR211 fix
66        saving/restoring floating point context.  The fpsave and fprestore
67        routines are only used in a executing context which _is_ fp and hence
68        has the FPU enabled. The current behavior required the FPU always to
69        be on which is very dangerous if lazy context switching is used. 
70        [Joel Note: Some ports explicitly enabled the FPU in the FP save and
71        restore routines to avoid this.]
72
73        The patch also makes sure (on powerpc only) that the FPU is disabled
74        for integer tasks. Note that this is crucial if deferred fp context
75        switching is used. Otherwise, fp context corruption may go undetected!
76        Also note that even tasks which merely push/pop FP registers to/from
77        the stack without modifying them still MUST be FP tasks - otherwise
78        (if lazy FP context switching is used), FP register corruption (of
79        other, FP, tasks may occur)!
80
81        Furthermore, (on PPC) by default, lazy FP context save/restore
82        is _disabled_.

85
86        * rtems/score/cpu.h: Removed.
87        * Makefile.am: Reflect changes above.
88
892001-04-03      Joel Sherrill <joel@OARcorp.com>
90
91        * Per PR94, all rtems/score/CPUtypes.h are named rtems/score/types.h.
92        * rtems/score/cpu.h: Account for name change.
93
942002-03-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
95
96        * configure.ac:
97        AC_INIT(package,_RTEMS_VERSION,_RTEMS_BUGS).
98        AM_INIT_AUTOMAKE([no-define foreign 1.6]).
99        * Makefile.am: Remove AUTOMAKE_OPTIONS.
100
1012001-11-28      Joel Sherrill <joel@OARcorp.com>,
102
103        This was tracked as PR91.
104        * rtems/score/cpu.h: Added CPU_PROVIDES_ISR_IS_IN_PROGRESS macro which
105        is used to specify if the port uses the standard macro for this (FALSE).
106        A TRUE setting indicates the port provides its own implementation.
107        * rtems/score/c_isr.inl: Deleted and contents merged into cpu.c.
108        * cpu.c: Received contents of c_isr.inl.
109        * Makefile.am: Deleted reference to c_isr.inl.

1112001-11-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
112
113        * .cvsignore: Add aclocal.m4, autom4te.*, config.*, configure.
114
1152001-11-21      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
116
117        * Makefile.am: Preinstall c_isr.inl (HACK).
118        * ChangeLog: New file.
