fvdl 9b4c0e34d2 Initial commit of the port to AMD's upcoming 64 bit architecture, the 
x86-64. Since there's no hardware available yet, this port is only
known to run on the Simics simulator for at the moment, and as such
uses the PC devices that it simulates for now. It will be developed
more (and cleaned up) as the hardware becomes available.

fredette 49fda862f9 When MACHINE_ARCH is m68000, compile ffs.c and random.c 
instead of ffs.s and random.s, and sneak the libgcc
integer support routines into the list of library objects.

fredette 332aa50acb Use the EXTBL macro where we want the extbl instruction. 
On the 68010 this expands to an extw/extl combination.

fredette 8ba384c841 On the 68010, we are forced to do bytewise compares 
and copies if the two addresses aren't of the same
evenness.

bjh21 af14995e51 Create a shared set of ARM sources for libkern and move arm26 over to using 
them.

These are identical to the current arm32 sources with the following exceptions:
 - References to C labels are wrapped in _C_LABEL().
 - Function returns have an alternate version inside #ifdef __APCS_26__.

itojun 65363da25e 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).

jonathan 008816ea4f Changes to sys/arch/mips from ARC port, from Noriyuki Soda <soda@sra.co.jp>. 
Adds (most) support for ARC platform to port-independent mips code.

Some changes (e.g., clean up of overlapping CPU/FPU ids) inspired by
comparison to the OpenBSD 2.1 codebase of Soda's ARC port.

Open issues:
 * Still no support for r4600 or mipsIV CPUs with two-way L1 cache.
   Code derived from Per Fogelstrom's OpenBSD source  doesn't work
   on mips3 pmaxes with L2 cache.

 * Still some port-specific  #ifdefs, for interrupt enable and
   pmax L2 cache-size.  Needs more thought, but overlaps with
   work-in-progress by Tohru and Tsubai on spl()s and related stuff.

can occur when dividing MIN_INT by certain values.

scottr c49762b3d3 Implement assembly byte-swap functions. 1997-10-11 04:28:40 +00:00
bouyer 6ab3092b11 Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern. 
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

cgd d867ed50cc add strchr() to libkern. strchr.c copied from libc's "index.c", but with 
appropriate definitions so that it'll build strchr(), and so that it builds
correctly in libkern (needed to #define NULL).
