Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.
Optimalization on IA-32 disabled.

/SPARTAN/trunk/test/fpu/fpu0/
Add check for infinite loops in e().
88

Rename test/fpu/fp0 to test/fpu/fpu0.
(Couldn't do it in one go.)
87

/SPARTAN/trunk/
Rename test/fp to test/fpu.
86

Add BSD license and copyright line.
Coding style and small improvements.

/SPARTAN/trunk/arch/ia32/boot/
IA-32 boot Makefile bugfix.
Previous version did not take 512B of boot sector code into account and produced wrong image.bin.

IA-32 FPU lazy context switching.
Doesn't work on Bochs and sometimes produces wrong results on P4.
Seems to work on VMware and PII.
Build script for IA-32 changed to build floppy images (image.bin) 1440K long.
83

/SPARTAN/trunk/arch/ia64/
IA-64 work.
Add ar.pfs and ar.unat (caller and callee) application registers to context_t.
Change st8/ld8 instructions on general registers to st8.spill and ld8.fill instructions.
82
7028 d 18 h

/SPARTAN/trunk/arch/
IA-64 work.
Add the rest of branch registers to context_t.
Add predicate registers to context_t.
Modify context_save()/context_restore() to save/restore branch registers and predicate registers.
Change SP_DELTA to 0 since both context_save() and context_restore() are leaf procedures and as such don't use the scratch area.
Change pri_t to be __u64 instead of __u32.
81

Add SP_DELTA macro for each architecture.
On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.
IA-64 work.
Changes in start.S. More changes to come.
Define memcopy().
Janitorial fixes.
Add missing #include <panic.h> to rwlock4/test.c.
Remove wrong use of inline keyword from both declaration and definition of l_apic_id().

IA-64 cosmetics.
Add ski_init_console() and ski_putchar() to ski.c to perform ski specific tasks.
Change the copyright string in main.c to display both copyrights on a new line.
77
7032 d 20 h

Add %P and %p formatters to printf for printing pointers in maximum bit width.
Add %Q and %q formatters to printf for printing 64-bit integers.
76
7033 d 20 h
jermar
/SPARTAN/trunk/
For each architecture, add function/macro FADDR that calculates absolute address of a function referenced by void (* f)(void).
IA-32 and MIPS gcc's use direct addressing (f == FADDR(f)) while IA-64 gcc uses indirect addressing (f != FADDR(f)).
Tweaks in IA-64 Makefile.inc to declare constant gp and main Makefile to consider ASFLAGS when compiling .s targets.
75

Move fpu_owner pointer from cpu_arch_t to cpu_t.
74

More of IA-64 initialization.

Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK.
