matt cb520da5b3 Refresh from libc. 2002-03-28 00:46:08 +00:00
fredette 58830d68c5 Added brand-new integer multiply and divide support, used only
on the m68000.

matt 12810ed37d Use size_t in prototype (so this will be LP64 clean for PPC64 someday).
Calculate len separately for icache & dcache in case each has different
cacheline widths.  Make the code for both loops the same except for the
dcbst/icbi.  Deal with sizes >=2GB properly (like that'll happen but ...)
2002-03-26 21:20:24 +00:00
fredette d617871b0c On the m68000, if and only if gcc doesn't seem to know
where libgcc.a is, fall back to one under DESTDIR.

matt e2d6f22138 Add register prefixes to these. 2002-02-24 00:12:41 +00:00
matt 6cad4b795d Upon further reflection, move udiv/urem to libkern and out of vax/vax. 2002-02-24 00:08:19 +00:00
ragge f2d946a56e blkset() used a register for set value that get clobbered by movc5,
causing the set area to get unpredictable contents.
2002-02-19 21:46:17 +00:00
thorpej 2362fef9a8 Add __blkcpy() and __blkset() (renamed/modified from __blkclr()) to
libkern.

thorpej 5ed948ecea The kernel is now built with -ffreestanding, so GCC built-ins are
disabled.  Explicitly re-enable some that we want to use, namely:

* memcpy() -> __builtin_memcpy()
* memcmp() -> __builtin_memcmp()
* memset() -> __builtin_memset()

* strcpy() -> __builtin_strcpy()
* strcmp() -> __builtin_strcmp()
* strlen() -> __builtin_strlen()

We might also consider some others for GCC 3.x.

wiz b4371d47f5 Replace some misuses of "then" with "than". 2001-12-04 17:56:30 +00:00
mjl f14e78b4c3 Disable bzero/memset assembler implementation until the dependency
problem on assym.h is sorted out and TRW to get at CACHELINESIZE in
the kernel is determined.

mjl 8231ab74c5 Add assembler version of strlen. 2001-11-30 02:27:20 +00:00
mjl 625c08cf7e Outifdef some stuff not needed in the _KERNEL case. 2001-11-30 02:25:50 +00:00
mjl 4ee3b0f097 Add assembler versions of ffs, bzero and memset. 2001-11-29 00:27:07 +00:00
jmc 2229499bfb Don't make clean and cleandir depend on the lib subdir. Just check for it's
existance before running the submake. This makes it possible to run a
make build (which runs cleandir before make obj) in a r/o source tree

chris 9cc0f33345 Tidy up some memory copying cruft:
bcopy.S is no longer needed
memmove and memcpy were both stacking r0 and unstacking it to keep the return value, so push this down into _memcpy.
rename _memcpy.S to memcpy.S.
memmove.S is now just a placeholder otherwise the make system automagically adds a memmove.c file to libkern.
memmove is just another entry point for memcpy.

tv 4446c00002 Undefine DESTDIR; we don't want the special DESTDIR <bsd.lib.mk>
handling for kernel libraries.

XXX this build method should be replaced by something more sane

chris 4d1b8d545e Sync to libc version of divsi3.S. This is to fix up the stack for 8 byte alignment. 2001-11-13 20:06:40 +00:00
matt 920cfb5205 Add "Red Black +" balanced binary tree routines to libkern. These provide
O(log(N)) insertation, deletion, and lookup times.  However, unlike most
red-black implemenations, this one does no additional memory allocations.

uch 07f8f33bb9 R5900 miss-prediction of branch targets for short-loop. 2001-10-16 15:40:53 +00:00
fvdl f22b808267 Make new gas happy. Use movzbl instead of xorl + movb. 2001-09-21 14:14:30 +00:00
fredette 7aaa6a4bc4 On the 68010, don't bother with the by-8-longwords loop, instead
only 16-bit align the region and use loop mode with longwords
to do the bulk of the work.

On the 68020+, fixed an optimization bug where all regions that start
on odd addresses would not be properly longword aligned.

itojun 9fe945f2fe sync argument/return type of [hn]to[nh][ls] to XNET 5.2 (uint{16,32}_t).
as discussed on tech-net.

jdolecek c495131fe3 Move _insque()/_remque() to libkern. Once remaining uses would
be converted to <sys/queue.h> macros, _insque()/_remque() would be eliminated
altogether.
2001-08-12 08:35:31 +00:00
lukem 9bbc26f3dc convert to ansi knf, and fix a bug where the last arg was incorrectly
'u_char' instead of 'int' (per the prototype and usage and other scanc
implementations)

thorpej ac8a2539c1 Provide bcopy() here. 2001-07-13 00:04:00 +00:00
perry 5624bbb1d4 restore bzero and bcmp prototypes for now -- this has to be hashed out. 2001-07-07 17:22:25 +00:00
simonb 5439e1a9ff Put the prototypes for bcmp() and bzero() back (ifdef _STANDALONE) so that
libsa builds again.
2001-07-07 12:23:43 +00:00
perry 7ab9c62227 Remove bcmp and bzero prototypes. And yes, I actually checked and
tested this time. (Slap self repeatedly.)
2001-07-07 05:42:16 +00:00
toshii 70e10fb682 Remove bcmp, bcopy and bzero. We don't need them as they aren't
called from asm code, and we shouldn't have them if we don't need them.

kleink e69c885f3e Sync with libc: use bzero-based assembly version of memset(). 2001-07-01 11:55:36 +00:00
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.
2001-05-16 03:30:39 +00:00
fredette 332aa50acb Use the EXTBL macro where we want the extbl instruction.
On the 68010 this expands to an extw/extl combination.
2001-05-16 03:14:12 +00:00
fredette 8ba384c841 On the 68010, we are forced to do bytewise compares
and copies if the two addresses aren't of the same
evenness.

kleink 95fa77ab80 Make this work for PIC (as opposed to pic) without taking chances of fitting
__ffstab into a GOT13 relocation; from Eduardo Horvath.
