from Eric Norum <eric@cls.usask.ca>. This patch was rtems-19990820-0-diff
from Ralf.
FYI: In parallel to the transition to automake, RTEMS is on a transition
from make-time configuration to per-bsp and per-bsp configuration at
configuration-time. Due to this several changes to configuration files
have been added and might have broken something that has been working
previously. Most noticeable behavioral change is that you now are required
to use @RTEMS_BSP@ instead of $(RTEMS_BSP) inside of any Makefile.ins
which are configured or build as part of the source-tree.
> It used to be that only RTEMS_MAKEFILE_PATH had to be set. Why is this
> no longer sufficient?
It should still be working, if it doesn't, it has to be considered to be
broken and should be fixed.
I am not sure, but I assume you are using Makefile.inc - In this case, you
have found a bug in Makefile.inc.in which should be worked-around by the
patch below. If my assumption is wrong, I would need more details ...
c/src/lib/librtems++ and c/src/lib/include/rtems++ to
their own package librtems++ at the top of the tree.

Somehow a nasty bug has made it in sh/start.S ("|", instead of "!", to
begin an asm comment).
I have no idea how this could remain undiscovered for so long (It is in
rtems-4.0.0, too!), however upgrading to binutils from sourceware's CVS
sh-rtems-as chokes on this bug. => I guess, either binutils changed its
conventions or an obvious bug in as has been fixed.
This patch addresses a few configuration issues and removes some
duplicate configuration files.
Background:
* some files used in AC_INIT were not unique enough and can lead to
problems if a user plays with configure scripts.
* the Makefile templates are independent of the target/cpu and bsp, so
the bsp dependent versions (c/src/make/Templates) are removed.

ATTENTION: This patch removes several files and one directory :)
1. Addition of maintainer-mode dependencies on config.status and
aclocal.m4 for autoconf toplevel Makefile.ins. These rules are taken
over from automake generated Makefile.ins, i.e. they are contained in
any automake generated toplevel Makefile.in. Having this patch in is at
least a great releaf for me when working on RTEMS configuration :)
2. Automated support for #1 in acpolish
3. Some minor "beautifications" on Makefile.ins resulting from running
acpolish.
FYI: This patch has been generated by running
tools/update/rtems-polish.sh -ac on the source tree and manually editing
the resulting patch afterwards to work around a problem with acpolish,
which still corrupts one Makefile.in - WARNING: Be careful with running
acpolish!

I expect this patch not to have any influence on normal users, unless
they use --enable-maintainer-mode, thus merging it should be rather
harmless.

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.

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.

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.
<raguet@crf.canon.fr>:
- the dec21140 driver code has been hardened (various bug fixed) Emmanuel,
- bug in the mcp750 init code have been fixed (interrupt stack/initial
stack initialization), BSS correctly cleared (Eric V)
- remote debugging over TCP/IP is nearly complete (berakpoints,
backtrace, variables,...) (Eric V),
- exception handling code has also been improved in order to fully
support RDBG requirements (Eric V),
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.

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.
The patch below fixes a nasty bug in acpolish, which has broken many
