* asm.h, cpu.c, rtems.c, rtems/score/cpu.h, rtems/score/sh.h, rtems/score/sh_io.h, rtems/score/shtypes.h: Consistency changes and made sure there were no includes from the libcpu tree.

* cpu.c, rtems/score/cpu.h, rtems/score/sh.h: Modified to support SH4. Reviewed by Ralf Corsepius <corsepiu@faw.uni-ulm.de> who did the original SH port.
2001-10-122001-10-12 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-2/+8
* cpu_asm.S: _CPU_Context_save_fp in was incorrectly in conditional compilation block with (CPU_HARDWARE_FP == FALSE). Reported by Wayne Bullaughey <wayne@wmi.com>.

* cpu_asm.S: Small patch to fix a bug in the rtems sparc port. The bug has been there all the time, but only hits the leon bsp since the leon cpu has a 5-stage pipeline (erc32 has 4 stages).

* include/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='. * include/rtems/Makefile.am: Use 'PREINSTALL_FILES ='. * inline/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='. * macros/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.

* src/threadhandler.c: Now process C++ global constructors (_init) as part of the first task execution not in BSP space. This depends on the toolset defining USE_INIT_FINI so you have to have the right toolset version.

* src/coremutex.c, src/coremutexseize.c, src/coremutexsurrender.c, inline/rtems/score/coremutex.inl: The per thread field resource_count should only be manipulated when a mutex is priority ceiling or priority inherit. This was reported by Chris Johns <ccj@acm.org> who also noticed that the use of switches for all disciplines generated less efficient code than using explicit tests for the one or two cases we were really interested in. Further review of his modifications made it apparent that the "isa" methods to test mutex discipline were not being used so this modification was swept into the code as well.
2001-08-302001-08-30 Joel Sherrill <joel@OARcorp.com>Joel Sherrill1-0/+7
* src/coremutexseize.c: Add missing code for proper handling of nesting acquisitions. This only impacts building with inlines disabled on the source with the "fast mutex" optimizations. This was post the 4.5 branch and did not impact released versions.
2001-08-162001-07-25 Radzislaw Galler <rgaller@et.put.poznan.pl>Joel Sherrill2-1/+10
* cpu.c (_CPU_ISR_install_vector): Corrected interrupt range checking which was SH1 specific. It didn't work for SH2 (has more interrupt sources).
2001-08-162001-08-16 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-1/+7
* src/coremutexsurrender.c: Use holder thread not executing thread because even though they may and often are the same it is not guaranteed unless the proper attribute is set.
2001-08-162001-08-16 Joel Sherrill <joel@OARcorp.com>Joel Sherrill3-2/+11
* include/rtems/score/coremsg.h, src/coremsgsubmit.c: Add a new return status to account for blocking sends. Otherwise, the caller will think that the returned message status will have the ultimate results of the operation. If the send times out, the final status will be in the return_code of the thread.
2001-08-092001-08-09 Chris Johns <ccj@acm.org>Joel Sherrill2-63/+48
* cpu_asm.S: This patch was co-developed with Eric Norum <eric.norum@usask.ca>. It closes a one instruction window on some m68k CPU cores. It fixes symptoms seen as: 1) No more `interrupt handler invoked twice for a single interrupt'. 2) No more `lockup when mc68360 CPM and PIT interrupts are at different levels'. It does insert a little more overhead on machines without hardware interrupt stacks but correctness has a price.
2001-08-092001-08-09 Joel Sherrill <joel@OARcorp.com>Joel Sherrill4-29/+50
* include/rtems/score/coremsg.h, inline/rtems/score/coremsg.inl, src/coremsgsubmit.c: Unblocking message queue operations should NOT use _Thread_Executing for return status since it is permissible to invoke message send operations from an ISR. This was reported by Suvrat Gupta <suvrat@utstar.com>.
2001-07-032001-07-03 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-1/+5
* cpu.c: Fixed typo.
2001-05-252000-05-25 Sergei Organov <osv@javad.ru>Joel Sherrill3-2/+6
* macros/rtems/score/coresem.inl, inline/rtems/score/coresem.inl: Cut and paste problem incorrectly enabled interrupts twice with the first time being too early.
2001-05-242000-05-24 Joel Sherrill <joel@OARcorp.com>Joel Sherrill1-7/+38
* rtems/score/mips.h: Added constants for MIPS exception numbers. All exceptions should be given low numbers and thus can be installed and processed in a uniform manner. Variances between various MIPS ISA levels were not accounted for.

* Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>. * cpu_asm.S: Now works on Mongoose-V. Missed in previous patch.
2001-05-222001-05-22 Greg Menke <gregory.menke@gsfc.nasa.gov>Joel Sherrill3-21/+86
* rtems/score/cpu.h: Add the interrupt stack structure and enhance the context initialization to account for floating point tasks. * rtems/score/mips.h: Added the routines mips_set_cause(), mips_get_fcr31(), and mips_set_fcr31(). * Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.
2001-05-092001-05-09 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-0/+9
* include/rtems/score/.cvsignore: Add stamp-h, cpuopts.h, cpuopts.h.in, cpuopts-tmp.h.
2001-05-082001-05-07 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-2/+4

2001-05-072001-05-07 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-67/+95
* cpu_asm.S: Merged patches from Gregory Menke <Gregory.D.Menke.1@gsfc.nasa.gov> that clean up stack usage and include nops in the delay slots.
2001-04-202001-04-20 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-0/+15
* cpu_asm.S: Added code to save and restore SR and EPC to properly support nested interrupts. Note that the ISR (not RTEMS) enables interrupts allowing the nesting to occur.
2001-04-112001-04-11 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-2/+4
* cpu.c: Removed duplicate declaration for _ISR_Vector_table.

2001-03-142001-03-13 Joel Sherrill <joel@OARcorp.com>Joel Sherrill6-722/+405
* cpu.c, cpu_asm.S, iregdef.h, rtems/score/cpu.h, rtems/score/mips.h: Merged MIPS1 and MIPS3 code reducing the number of lines of assembly. Also reimplemented some assembly routines in C further reducing the amount of assembly and increasing maintainability.
2001-02-052001-02-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill49-113/+191

* rtems/score/mips.h (mips_get_sr, mips_set_sr): Corrected register constraints from "general" to "register".
2001-01-092001-01-09 Joel Sherrill <joel@OARcorp.com>Joel Sherrill4-6/+27
* cpu_asm.S: Use SR_INTERRUPT_ENABLE_BITS instead of SR_XXX constants to make it easier to conditionalize the code for various ISA levels.
2001-01-082001-01-08 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-0/+9

2001-01-082001-01-08 Joel Sherrill <joel@OARcorp.com>Joel Sherrill4-3/+16
