329 6863 d 6 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
327 6863 d 22 h palkovsky /SPARTAN/trunk/ Doc updates, small fixes.  
326 6863 d 22 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.		  
324 6864 d 9 h palkovsky /SPARTAN/trunk/ MIPS architecture now works without any problems in
- msim: compile as OUTPUT_FORMAT(binary)
- gxemul: compile as OUTPUT_FORMAT(ecoff-littlemips), or create
configuration file for binary format (will be done later)
- simics: compile as OUTPUT_FORMAT(elf32-little), might work with binary
format, didn't try yet.		  
320 6865 d 2 h palkovsky /SPARTAN/trunk/arch/mips/src/ Bad stack settings. Why did not msim complain??  
319 6866 d 13 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
317 6866 d 13 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
314 6867 d 0 h palkovsky /SPARTAN/trunk/ Small cleanups  
313 6867 d 0 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.		  
309 6867 d 13 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
308 6867 d 14 h jermar /SPARTAN/trunk/arch/mips/src/ Just formatting changes.  
306 6867 d 14 h palkovsky /SPARTAN/trunk/ Fixed mips boot process.
On interrupt saving registers, save $lo, $hi.
Add interrupt naming to asm files (mips).
Save only necessary registers on context switch (see mips ABI).
Fixed copyright info.		  
268 6870 d 6 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
266 6870 d 9 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
240 6872 d 4 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad register assignment in atomic.h.
Added -msoft-float so that it does not call coprocessor and it works withou doubles.
Removed undefined symbol from tlb.c. Unfortunately
mips linker does not report missing symbols.		  
237 6872 d 5 h palkovsky /SPARTAN/trunk/arch/mips/src/ Fixed missing semicolon;  
230 6872 d 8 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.		  
227 6872 d 8 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.		  
213 6873 d 1 h jermar /SPARTAN/trunk/ Add some comments.  
212 6873 d 1 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......
