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.

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 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.

lukem 2565646230 don't need <sys/types.h> when including <sys/param.h> 2001-11-15 09:47:59 +00:00
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
christos c89e803d30 Remove USB copyrights. The coff and elf loading code did not come with BSD4.4. 2001-11-09 19:27:25 +00:00
scw f1defc3543 To avoid backwards seeks on sequential devices (eq. QIC tapes), read all 
the program headers in one operation into an internal buffer.
 2001-11-09 18:31:08 +00:00
thorpej 0971f93345 Make the ELF loadfile routines byte-order independent when used in 
a non-_STANDALONE environment (e.g. installboot(8)): internalize and
externalize the exec, program, and section headers as necessary.

Reviewed and OK'd by Christos.

thorpej a43b4351a8 Oops, committed wrong copy of file in previous revision. 2001-10-31 20:22:22 +00:00
thorpej 90aee7593a Add standalone 64-bit to/from {big,little}-endian routines. 2001-10-31 20:19:52 +00:00
thorpej e727e3f180 Split elf32 vs. elf64 handling in loadfile(), including support for 
each separately and explicitly.  BOOT_ELF is now BOOT_ELF32 and
BOOT_ELF64, and ELFSIZE should no longer be defined in loadfile_machdep.h.
 2001-10-31 17:20:45 +00:00
thorpej 4810d73020 Build the loadfile() a.out, ECOFF, and ELF back-ends as separate 
objects.
 2001-10-31 01:51:42 +00:00
thorpej 91626c3515 Split the exec formats included by loadfile() into separate files. 
Primary goal: explcitly select which ELF format (elf32 or elf64) to
support for a cross tool which uses loadfile().
 2001-10-30 23:51:03 +00:00
thorpej 74eebee33c Add standalone byte-swapping routines that don't require testing 
the system's byte-order:
- host to {big,little}-endian {16,32}
- {big,little}-endian {16,32} to host

These are not intended to be used in libsa directly, but are rather
intended to be used by host tools which may use libsa routines (such
as loadfile()) which need to use explicit byte-ordering.

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.

minoura 12ea5d8238 Add changedisk_hook(). 
Machine-dependent code can eject the floppy to prompt the next volume in it.
(Or add another method in devsw?)

wiz 4c99916337 va_{start,end} audit: 
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

Improved by comments from enami and christos -- thanks!

Heimdal/krb4/KAME changes already fed back, rest to follow.

Inspired by, but not not based on, OpenBSD.

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.

tsutsui cf574991b8 Add a small version of memmove() for libsa. 
Mostly identical with libsa/bcopy.c.

jdolecek c495131fe3 Move _insque()/_remque() to libkern. Once remaining uses would 
be converted to <sys/queue.h> macros, _insque()/_remque() would be eliminated
altogether.

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)

bjh21 acf574f63e When loading ELF, zero out: 
The e_shstrndx field in the ELF header, since we don't load .shstrtab.
The sh_name field in each section header, for the same reason.
The sh_offset field for any section we don't load.

This means the kernel has some chance of knowing what it's being given.  It
also means that the behaviour of old kernels with new loaders should be
deterministic (if not terribly useful: they still can't find the symbol
table).
 2001-07-31 22:11:57 +00:00
bjh21 30f144749a G/C "off", since it was just tracking the difference between maxp and elfp. 2001-07-31 21:09:52 +00:00
bjh21 67a82e1d4e Fix a small memory leak when counting the size of the symbol table (shp was 
ALLOC'ed if (LOAD_SYM|COUNT_SYM), but FREEd if (LOAD_SYM)).

bjh21 1a35da3617 When loading an ELF kernel, don't load all the STRTAB sections. Instead, just 
load those STRTAB sections that are referenced by a SYMTAB that we're loading.

The main advantage of this is that (at least with the binaries output by my
ARM ELF linker) this removes the need to seek backwards through the file, which
is a big win when loading a gzipped kernel.

While we're here, don't allocate space for string tables we don't load.

christos 366971a414 Back out previous. The booter will need to find the symbol table itself, 
as explained in the code.

simonb 5439e1a9ff Put the prototypes for bcmp() and bzero() back (ifdef _STANDALONE) so that 
libsa builds again.
