315 6848 d 10 h jermar /SPARTAN/trunk/arch/ia32/ Make IA-32 userspace stack be aligned on doubleword boundary.
In userspace(), mark "eax" as clobbered register.		  
312 6848 d 20 h jermar /SPARTAN/trunk/arch/ia32/ According to IA-32 ABI, %edx and %ecx don't have to be saved accross function calls.
Remove these registers from context_t and adjust context_save() and context_restore() to make use of this fact.		  
309 6849 d 8 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
303 6850 d 2 h palkovsky /SPARTAN/trunk/  
300 6850 d 5 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
292 6850 d 19 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().		  
282 6851 d 10 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.		  
280 6851 d 18 h decky /SPARTAN/trunk/arch/ia32/ basic GRUB memory map  
279 6851 d 20 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
275 6851 d 23 h palkovsky /SPARTAN/trunk/arch/ Moved AMD64 kernel above 1MB.  
273 6852 d 0 h palkovsky /SPARTAN/trunk/ Changes to make ia32 smp code not architecture dependent.
Changes to accomodate new gdtr loading scheme.		  
269 6852 d 1 h decky /SPARTAN/trunk/arch/ia32/ make IA-32 SMP work again (finally)  
268 6852 d 1 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
267 6852 d 2 h decky /SPARTAN/trunk/arch/ia32/ proper way of initializing GDT during boot on IA-32, fixes the nasty hack
SMP might be still broken		  
266 6852 d 4 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
259 6852 d 6 h palkovsky /SPARTAN/trunk/ Fixed asm problems in asm in atomic instructions.  
248 6853 d 0 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
241 6853 d 23 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
235 6854 d 1 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
230 6854 d 3 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.
