326 6841 d 8 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.		  
323 6841 d 21 h jermar /SPARTAN/trunk/ Add comments for new floating point modifiers to print.c.
Remove left-over comments from AMD64 and IA-32 page.c.
Coding style clean up.		  
318 6843 d 23 h jermar /SPARTAN/trunk/ Make AMD64 gencontext.c consistent with MIPS gencontext.c  
317 6843 d 23 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
314 6844 d 9 h palkovsky /SPARTAN/trunk/ Small cleanups  
309 6844 d 23 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
307 6845 d 0 h palkovsky /SPARTAN/trunk/ Fixed things broken by last commit.  
306 6845 d 0 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.		  
303 6845 d 17 h palkovsky /SPARTAN/trunk/  
298 6845 d 21 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
295 6845 d 22 h palkovsky /SPARTAN/trunk/ Test that really tests SSE context switching.  
293 6846 d 9 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.
NOTE: gcc heavily inlines, be aware of optimizations.

Removed excesive item from boot page tables.		  
292 6846 d 9 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().		  
289 6846 d 13 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.		  
288 6846 d 15 h jermar /SPARTAN/trunk/ Create tools/ directory.
Move helper scripts and tools out of src/ and arch/.		  
284 6847 d 0 h palkovsky /SPARTAN/trunk/src/  
283 6847 d 0 h palkovsky /SPARTAN/trunk/ IA32 printf-double support migrated to amd64  
282 6847 d 0 h palkovsky /SPARTAN/trunk/ Fixed gdtr naming issues after ia32 changes.
Fixed stack alignment on new thread to by multiple of 16,
we are now ABI-correct and we do not #GP on va_arg to boot.
Fixed bad exception register names reporting.
Fixed bad _hardcoded_load_addr, which caused allocation of kernel text
frames.		  
276 6847 d 12 h cejka /SPARTAN/trunk/src/debug/ Printf "E" and "F" format fixed.  
274 6847 d 14 h palkovsky /SPARTAN/trunk/src/
