cb520da5b3 Refresh from libc. 2002-03-28 00:46:08 +00:00

58830d68c5 Added brand-new integer multiply and divide support, used only 
on the m68000.

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 ...)

where libgcc.a is, fall back to one under DESTDIR.

6440db6488 * Add a NetBSD Vendor Class Identifier option as proposed on tech-net 
in message <20020216172527.C23901@dr-evil.shagadelic.org>.
* Print the bootp/dhcp response, as is done for rarp/bootparam
  responses.
* Nuke bootp_flags and BOOTP_PXE; they're not used, nor should they be.

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.

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.

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.

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.

7aaa6a4bc4 On the 68010, don't bother with the by-8-longwords loop, instead

on odd addresses would not be properly longword aligned.

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).

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.
