75831c5b8f Build the syscalls (in libc, not libc_r) with weak symbols so that
libpthread can override them as required.

9b7c9bc4f8 Oops, backout the previous change having confused my underscores.
__thread_create is a syscall that uses the default asm. It is
_thread_create that contains specific asm code, but that lives in
libpthread.

3fece7a1aa Make cerror thread aware by calling __error() to get a pointer to the
thread-specific error variable. This change make libc use the same cerror
code that libc_r has been using.

68f87034f2 The syscall that creates a kernel thread is coming, but it doesn't use the
default syscall asm, so add it to NOASM. The other syscalls that manipulate
kernel threads use the default asm code, so they just get built
automatically.

0db2fac06a Nearly missed this one.
List non-default asm sources in MDASM so that they replace the defaults.

For funny or incomplete syscalls, list them in NOASM to stop them
from getting built as defaults.

7280dd1a3b Removed unused file. It just forces a return value of 0 on success
(no carry), but mount() in the kernel has returned 0 on success since
prehistoric times.

a461908da4 Handle machine-dependent (stdlib) sources more automatically.
This fixes bugs in the manual handling.  abs.[cS] was handled too
specially and the wrong (.c) variant for each of div.[cS], labs.[cS]
and ldiv.[cS] was added to SRCS.  This caused the .c variant to be
used if `depend' was made and the .S version to be used otherwise.

ae80efa54f Handle machine-dependent (m-d) (string) sources more automatically.
The names of m-d variants are now added (manually) to MDSRCS instead
of to SRCS, and the names of all machine-independent (m-i) variants
that can reasonably be replaced by an m-d variant are now added
(manually) to MISRCS instead of to SRCS, so that a simple substitution
can be used to discard the unused m-i variants.  MISRCS is potentially
all m-i sources, but the substitution is too simple to be fast, so
MISRCS should be kept reasonably small.

libc/Makefile.inc:
Do the substitution.

libc/i386/string/Makefile.inc:
Add to MDSRCS instead of to SRCS.  Add the names of all sources in this
directory, but no others.

libc/string/Makefile.inc
Add to MISRCS instead of to SRCS.  Add the names of all sources in this
directory.  Don't use (broken) explicit rules for special cases.

870039320f Changed all paths to be relative to src/lib instead of src/lib/libc
so that all these makefiles can be used to build libc_r too.

Added .if ${LIB} == "c" tests to restrict man page builds to libc
to avoid needlessly building them with libc_r too.

Split libc Makefile into Makefile and Makefile.inc to allow the
libc_r Makefile to include Makefile.inc too.

e23b7f75de Use separate routines for memmove() and memcpy(). This lets me drop
the (buggy) support for alternative entry points.  ALTENTRY() was only
used for memmove().  Optimizing for space was particularly silly because
memcpy() is rarely used (gcc normally inlines it).

1c33c5a76b Merged with the 1996/11/12 NetBSD version:
- use a slightly less bogus copyright.  This file was never contributed
  to Berkeley.  It still claims to be copright by the Regents.
- use <machine/asm.h> instead of "DEFS.h".
- use RCSID($Id$) instead of explicit assembly code and messy ifdefs.
  The rcsid won't be put into the object file until we make RCSID()
  non-null.  NetBSD uses a LIBC_SCCS ifdef here.  We used a LIBC_RCS
  instead, but I want RCSID() to be controlled directly by LIBC_RCS
  (actually by LIB_RCS).  This is the only difference with the NetBSD
  version.
- added ifdefs to support generation of memcpy() and memmove().  The
  other changes are "while I'm here" to get this.
- improved style of the copy backwards case.

Here are the diffs for libc_r to get it one step closer to P1003.1c
These make most of the thread/mutex/condvar structures opaque to the
user. There are three functions which have been renamed with _np
suffixes because they are extensions to P1003.1c (I did them for JAVA,
which needs to suspend/resume threads and also start threads suspended).

I've created a new header (pthread_np.h) for the non-POSIX stuff.

The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented
doesn't work. I think its best to delete it. I don't think libc_r needs
tags anyway, 'cause most of the source is in libc which does have tags.

also:

Here's the first batch of man pages for the thread functions.
The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was
inherited from /usr/src/lib/libc/Makefile that should only be done with
libc.

also:

I should have sent this diff with the pthread(3) man page.
It allows people to type

make -DWANT_LIBC_R world

to get libc_r built with the rest of the world. I put this in the
pthread(3) man page.  The default is still not to build libc_r.


also:
The diff attached adds a pthread(3) man page to /usr/src/share/man/man3.
The idea is that without libc_r installed, this man page will give people
enough info to know that they have to build libc_r.

95c715795a Fixed comparisons so that preposterously large (>= 0x80000000) brk values
aren't silently converted to minbrk.  This stops malloc(INT_MAX) from
dumping core.  Small values are still silently converted.  They should
be an error.  sbrk() doesn't do any range checking or conversions or
overflow checking.

Moved PIC_EPILOGUE invocation to a more natural place where it
obviously doesn't interfere with the comparison.

f1703dfbaa Add support to enable libc to be compiled in ELF format. (#ifdef __ELF__)
In a nutshell, this macroizes the local/global symbol scoping rules
that are different in a.out and ELF.  It also makes the i386 assembler
stubs conform to i386 PIC calling conventions - the a.out ld.so didn't
object, but the ELF one needs it as it implements PIC jumps via PLT's as
well as calls.  The a.out rtld only worked because it was accidently
snooping the grandparent calling function's return address off the stack..

This also affects the libc_r code a little, because of cpp macro nesting.

aacd7f348e Be smarter about handling overlapped copies and only go backwards if it
is really necessary. Going backwards on a P6 is much slower than forwards
and it's a little slower on a P5. Also moved the count mask and 'std'
