For unsignad integer division gcc used to emit a call to __udivsi3
"millicode" function that uses compiler-private ABI. Newer gcc uses
heavily tuned __udivsi3_i4i that is NOT compatible with __udivsi3
because it's expected to clobber different registers. We don't want
to link the kernel against libgcc and we don't have resources to write
heavily tuned version ourselves, so clone __udivsi3 but adjust it to
conform to the __udivsi3_i4i clobber spec.

Ditto for signed division.

You can make gcc use old routines with -mdiv=call-div1 to avoid few
extra instructions to save/restore the right registers in the signed
division funcion.

Move that majority of the 'SRCS+= foo.c' into the main Makefile.libkern.
Any .S files added by the arch/*/Makefile.inc cause the .c file to
be excluded.
Specific exclusions added using NO_SRCS to match previous files.
At least sparc, sparc64, i386, amd64 and vax GENERIC still build.
(There is a fubar with the naming of the byte-swap files ...)

Split the lines that add .c to SRCS from those that add .S
No changes (apart from the order) intended.

Provide __movmemSI12_i4 (gcc4) a.k.a. __movstrSI12_i4 (gcc3) that gcc
emits for sh4 to copy 12 bytes at certain optimization levels.
Discovered by compiling landisk kernel with -Os.

Use gcc3 naming ("movstr") to match the rest of the "movstr" files.

merge ktrace-lwp.

Use assembler version of bswap64.

Eliminate bzero.

Nuke bcopy. Move the code to memmove.S (which it is) make memmove the
primary entry point and comment out the bcopy entry point.

Kernels before and after the change are identical.

no need for bcmp.c

branches: 1.10.6;
Use assembly version of bzero() and memset().

add strtoul.c, it's now used in MI code.

Add __movstr_i4_{odd,even} for -m4.
Written by SHIMIZU Ryo.

Use assembly version of ffs(3).

branches: 1.6.2; 1.6.4; 1.6.16;
Add a strcasecmp(), modified from chopps's strncasecmp().

compile byte_swap_2.S and byte_swap_4.S

branches: 1.4.2;
new bcopy.S

branches: 1.3.2;
asm bcopy() for sh3

add strncasecmp.c

branches: 1.1.2; 1.1.4; 1.1.6;
Merge in NetBSD/sh3 from cvs.kame.net repository.

Tree structure:
- sys/arch/sh3: sh3 generic code
As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
