* cpu_asm.h: Removed.
* Makefile.am: Remove cpu_asm.h.
* rtems/score/mips64orion.h: Renamed mips.h.
* rtems/score/mips.h: New file, formerly mips64orion.h.
Header rewritten.
(mips_get_sr, mips_set_sr, mips_enable_in_interrupt_mask,
mips_disable_in_interrupt_mask): New macros.
* rtems/score/Makefile.am: Reflect renaming mips64orion.h.
* asm.h: Include <mips.h> not <mips64orion.h>. Now includes the
few defines that were in <cpu_asm.h>.
* cpu.c (_CPU_ISR_Get_level): Added MIPS ISA I version of this routine.
MIPS ISA 3 is still in assembly for now.
(_CPU_Thread_Idle_body): Rewrote in C.
* cpu_asm.S: Rewrote file header.
(FRAME,ENDFRAME) now in asm.h.
(_CPU_ISR_Get_level): Removed ISA I version and rewrote in C.
(_CPU_ISR_Set_level): Removed ISA I version and rewrote in C.
(_CPU_Context_switch): MIPS ISA I now manages preserves SR_IEC and
leaves other bits in SR alone on task switch.
(mips_enable_interrupts,mips_disable_interrupts,
mips_enable_global_interrupts,mips_disable_global_interrupts,
disable_int, enable_int): Removed.
(mips_get_sr): Rewritten as C macro.
(_CPU_Thread_Idle_body): Rewritten in C.
(init_exc_vecs): Rewritten in C as mips_install_isr_entries() and
placed in libcpu.
(exc_tlb_code, exc_xtlb_code, exc_cache_code, exc_norm_code): Moved
to libcpu/mips/shared/interrupts.
(general): Cleaned up comment blocks and #if 0 areas.
* idtcpu.h: Made ifdef report an error.
* iregdef.h: Removed warning.
* rtems/score/cpu.h (CPU_INTERRUPT_NUMBER_OF_VECTORS): Now a variable
number defined by libcpu.
(_CPU_ISR_Disable, _CPU_ISR_Enable): Rewritten to use new routines
to access SR.
(_CPU_ISR_Set_level): Rewritten as macro for ISA I.
(_CPU_Context_Initialize): Honor ISR level in task initialization.
(_CPU_Fatal_halt): Use new _CPU_ISR_Disable() macro.

<corsepiu@faw.uni-ulm.de> which implements automake support for some
score/cpu/<RTEMS_CPU> subdirectories and fixes a few minor configuration
bugs.
To apply:
rm -rf c/src/exec/score/cpu/a29k/wrap
rm -rf c/src/exec/score/cpu/hppa1.1/wrap
rm -rf c/src/exec/score/cpu/i386/wrap
rm -rf c/src/exec/score/cpu/mips64orion/wrap
rm -rf c/src/exec/score/cpu/no_cpu/wrap
patch -p1 < rtems-rc-19991123-rc-2.diff.gz
Notes:
* I don't see a possiblity to convert the powerpc subdirectory in its
current layout to automake the time being.
* Besides the fact that this subdirectory is not in single-tree building
layout, the actual showstopper is the ifeq $(RTEMS_CPU_MODEL),mpc750)
gmake-conditional in powerpc/Makefile.in, which automake (correctly)
refuses to handle.
* The problem is *not* specific to the powerpc. Other CPUs basically
have similar problems (SH:sh7032 vs sh7045, SPARC: erc32.h in
score/cpu/sparc), but have been lucky to get around real issues (cf.
configuration files below score/cpu/sh/).
* From a configuration focused POV this problem boils down to a
file/subdirectory selection problem:
ppc: 1 or others
sh: 1 out of 2
sparc: 1 out of 1
Automake's means to implement such behavior is using conditionals to be
evaluated at configuration-time. The old configuration scheme however
used make-time conditionals. The SH port was lucky to get around this
issue because it applies a selection from a limited set of possible
selections, the powerpc however applies a selection from an unlimited
set, based on data not being available at configuration time.
* Currently I only see two general solutions:
1) make RTEMS_CPU_MODEL available at configuration time, ie. replace
make-time configuration by configuration-time configuration
2) Perform the selection at build-time, i.e. always install all files,
but use #ifdef #else #endif in source files. This is what the m68k has
exploited at other locations inside of the source-tree.
=> This directory is the last one remaining not using automake below the
whole exec/ hierarchy.
