This one is a minor fix for the librdg-Makefiles for mcp750, mostly an
adaptation to the Makefiles used for the i386.

against 3.6.0 so was painful to merge. It should be OK but there
is no guarantee and there are no BSPs in the tree to exercise it.

Please take a look at this new patch. It contains a cleaner implementation
of the reset operation. These patches are against 4.0.0. But the files
did not change from the 3.6.0 release. Also, the cpu.h patch below still
applies. I.e. instead of using i960ca_PRCB, use i960_PRCB.
Explanation:
The previous patch removed the use of the reset instruction,
because it always fails. But this was due to the fact that
some of the registers were corrupted by the re-init procedure.
The new patches save and restore those registers when a re-init
is done.

Here is another fix, which addresses a few more or less severe bugs in
configuration and unix/posix:
* Configuration fix: c/src/lib/configure.in didn't handle RDBG correctly
* Configuration fix: make depend was non-functional in
c/src/lib/libc/Makefile.in
* Configuration fix: stray comment removed from aclocal/target.m4
* RTEMS fix: termios support for unix/posix now uses the host's headers
only (was completely broken).
- Don't install RTEMS's newlib sys/termios.h for unix (sys/termios.h
apparently is a newlib specific header)
- To be able to compile RTEMS's termios.c with glibc2.1, glibc-2.1
needs __USE_MISC, which is a private define from gcc's features.h, being
defined only when _BSD_SOURCE of _SVID_SOURCE is defined. RTEMS's
termios apparently implements BSD, thus -D_BSD_SOURCE was added to
Linux-posix.cfg.
- Conflicting definitions for __USE_MISC and _BSD_SOURCE inside of
RTEMS codes removed due to definition of _BSD_SOURCE on the toplevel.
This fix has been tested with linux/posix (primary glibc2.1 native),
linux/posix (secondary libc5 native), sh/gensh1, i386/pc386 and a couple
of other bsp's/CPU.
To apply:
cd <srcdir>
patch -p1 < rtems-rc-19990709-9.diff
and
aclocal -I aclocal && automake && autoconf
cd c/src/lib; autoconf
or
./autogen

After upgrading my linux box to the brand new SuSE 6.2 release, which is
glibc-2.1 based, I came across a bug in RTEMS - IIRC, I even warned you
about it about 1/2 a year ago, but nothing has been done since then :-.
The *.m4 macros to check for SYSV/IPC are broken for linux/glibc2.1,
because they assume that linux always defines union semun, which isn't
true anymore for glibc2.1 (the manpage for semctl states _X_OPEN
specifies it this way). Therefore I have tried to implement a more
general approach for handling SYSV for unix/posix which checks for
presence of struct semun, instead of trying to evaluate OS specific
preprocessor symbols.
This approach is a bit adventureous, because I only tested it with
linux/glibc2.1 and linux/libc5, but not under other Unix variants RTEMS
supports. I am quite confident it will work on other hosts, too, but who
knows :-.
[FYI: I think this might also is the cause of some problems with RedHat
6.X / Mandrake linux recently reported on the rtems list -- rtems-4.0.0
can not be build for posix on any glibc2.1 based host]
Furthermore the patch below contains a couple of minor fixes and
configuration cleanups, which IMO should be applied before releasing a
new snapshot.
To apply this patch:
cd <source-tree>
patch -p1 < rtems-rc-19990709-8.diff
./autogen

I'm attaching a big patch for the ts_386ex BSP which adds and includes
the following:
1) Conversion to ELF format + minor code cleanups + documentation.
2) An Ada95 binding to FreeBSD sockets, based on Samuel Tardieu's
adasockets-0.1.3 package. This includes some sample applications.
3) Some Ada and C interfaces to add serial-port debugging to
programs. Comes with examples, too; the Ada one shows how
transparent adding the support can be. Note that Rosimildo sent me
the original C code.
The network stuff is not BSP specific, and could be added to your Ada
code collection. The debugging stuff is specific to the i386. Right
now, everything sits in my "tools" directory.

I just released erc32ccs-2.0.6 which includes some fixes and the
Ada-self optimisation. Remote debugging of Ada programs did not
work due to a conflict between monior and rtems trap handlers.
I have attached a modified gnatsupp.c that makes remote debugging
possible again.

to fix problem reported by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
Date: Fri, 30 Jul 1999 14:53:20 -0500 (CDT)
From: <joel@oarcorp.com>
it is used like this in i386ex/start/start.S
/* set up same values in cache */
start.S: movw $0xFFFB, SYM(i8259s_cache)
I am heading out the door. Any other ideas what could have tripped this?
This instruction appears in a .code16 section. In a .code16 section,
current versions of gas assume that all addresses are 16 bits unless
told otherwise.
If you change the line to
addr32 movw $0xFFFB, SYM(i8259s_cache)
then you will get a 32 bit address reference.
You may want to use addr32 only when NEW_GAS is defined.
