82 6957 d 22 h jermar /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 6958 d 0 h jermar /SPARTAN/trunk/ 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().		  
79 6961 d 23 h jermar /SPARTAN/trunk/arch/ia64/src/ski/ doxygen-style comments  
78 6961 d 23 h jermar /SPARTAN/trunk/ 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.		  
76 6963 d 0 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.		  
74 6963 d 22 h jermar /SPARTAN/trunk/arch/ia64/src/ More of IA-64 initialization.  
68 6964 d 1 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs		  
63 6964 d 3 h decky /SPARTAN/trunk/ const qualifier for print functions  
60 6964 d 6 h jermar /SPARTAN/trunk/arch/ia64/ IA-64 work.
Give up attempts to persuade ld to patch the kernel image with proper hardcoded lenghts and addresses.
Add special sections and calculate the numbers manually.
Fix wrong order of operands in sub instructions in memcpy() implementation.		  
59 6964 d 20 h jermar /SPARTAN/trunk/ Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().

More complete and *almost* functional versions of IA-64 context_save() and context_restore().		  
57 6966 d 21 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
56 6966 d 21 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
55 6966 d 22 h jermar /SPARTAN/trunk/arch/ia64/src/ Add missing context.S.  
54 6966 d 22 h jermar /SPARTAN/trunk/arch/ Add missing '\' to Makefile.inc
Remove leading '_' from before_thread_runs_arch() in fake.s		  
52 6966 d 22 h vana /SPARTAN/trunk/ Move fpu_context switching functions from context.s to fpu_context.c on all platforms.
Add fpu_context.h.

Make before_thread_runs() arch-independent and create arch dependent version before_thread_runs_arch().		  
51 6967 d 1 h jermar /SPARTAN/trunk/ Small changes, fix last few wrong indentations.
TODO cleanup.

IA-64 bits.
Call main_bsp from kernel_image_start().
Prepare for IA-64 context_save and context_restore.		  
50 6967 d 5 h jermar /SPARTAN/trunk/ Big indentation update.

Add Jakub Vana to AUTHORS.

Minor fixes.		  
45 6967 d 10 h vana /SPARTAN/trunk/ Added fpu_context_t type.
IA-32's version of this type contains array of 512 bytes to be used by FXSAVE ... instructions.		  
42 6967 d 23 h jermar /SPARTAN/trunk/ Add stdarg.h to support variable argument list functions on architectures with compiler support for __builtin_va_*.
stackarg.h is kept for those architectures which lack that kind of support and for testing purposes.

Make printing functions use the __native type and support the maximum integer width.		  
40 6969 d 7 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.
