because we were unable to find correct solution to compile on various
linux distros (due to rpcgen incompatibilities), and because the coding
style of rdbg was rather inconsistant among various pieces of code, I
decided to:
1) make some cleaning regarding global coding style (using
indent + manual edits),
2) incorporate/review the paches send by various people
(S. Holford, T. Strauman),
3) Fix the bug due to varying rpcgen code generation
in remdeb_svc.c,
4) Remove some dead code,
5) Apply a patches enabling to call enterRdbg imediately
after rdbg initialization is done,
NB : the paches is huge but it is mainly due to coding styke chnages.
Only few lines of codes have been really changed and they do not impact
rdbg functionnality (AFAIKT).

Ralf Corsepius <corsepiu@faw.uni-ulm.de> that contain:

Makefile.ams
* Adds automake support to all remaining BSPs which have not yet been
converted to automake.
* Makefile.am for all remaining wrapup/Makefile.ams
|
|
that addresses the librdbg/rpcgen related problems:
Changes:
* All rpcgen generated files are now kept inside of the source tree
* Fix librdbg/configure to correctly detect presence of rpcgen and awk
* Use rpcgen -m to generated remdeb_svc.c
* Remove msgout/_msgout from awk.svc
* minor cleanups to librdbg/configure.in
ATTENTION --- IMPORTANT:
* With keeping rpc-generated files pre-build inside of the source tree,
you as the packager of RTEMS have to ensure that timestamps are
correctly set up: The generated files must not be older than the *.x
files.
* This is extraordinarily important when
- putting the package on read-only media
- after checking out from CVS
- after modifications to the *.x files
* If one of the *.x files is modified you have to either
- build for i386/pc386 and powerpc/mcp750
- or to invoke the same rpcgen calls as the
librdbg/src/<cpu>/<bsp>/Makefile.am do manually
before checking-in the files to CVS.
Proposal:
We could add something to bootstrap for touching the rpcgen-generated
sources and/or to manually regenerate them.
NOTE FROM JOEL:
Ralf proposed modifying bootstrap to handle rpcgen. I think this
is the best solution as it is something already done in the
snapshot procedure.

<corsepiu@faw.uni-ulm.de>:
The patch below provides
* automake support for score/cpu/powerpc
* The hack to propagate values from *.cfg to automake configuration
* A fix for librdbg/powerpc/mcp750/Makefile.am (Was completely corrupted
before)
* Fixes some files which apparently where missing in
rtems-rc-19991123-rc-2.diff
* some minor configuration related patches
To apply:
rm -rf ./c/src/exec/score/cpu/powerpc/wrap
patch -p1 < rtems-rc-19991123-rc-3.diff
Attention:
c/src/exec/score/cpu/[configure.in|aclocal.m4|configure] should be
removed after applying the patch.
Modifications had been made to the score/cpu/powerpc directory after
the snapshot this was based on. In particular, the mpc750 and
other_cpu directories had been renamed to new_exception_processing
and old_exception_processing. After this patch was applied, modifications
were made to account for this.

The patch below actually consists of 3 patches:
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.

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

The main topic is replacing the hard-coded values for HAS_MP and
HAS_RDBG in custom/*.cfg with per-bsp configuration-time autoconf checks
(This is the patch I had mentioned before earlier this week).
CHANGES
* HAS_MP removed from custom/*.cfg, replaced with configuration time
autoconf check
* HAS_RDBG removed from custom/*.cfg, replaced with configuration-time
autoconf check
* NEW: c/src/make/bsp.cfg.in, takes configuration-time checked per-bsp
values (i.e. HAS_MP, HAS_RDBG), gets installed as
$(prefix)/<bsp>/make/bsp.cfg
* NEW: default.cfg includes bsp.cfg - this change is backward
compatible.
* IMPORT_SRC: apply VPATH instead for ts_386ex/i386ex subdirectory
Makefile.ins
* HACK: a bug in acpolish mis-handles addtions to makefile variables
which are enclosed in gmake conditionals:
c/src/lib/libbsp/m68k/ods68302/start302/Makefile.in
* Apply inline_dir, HAS_MP and HAS_RDBG for avoiding configuration of
unneeded subdirectories in various configure.in files.
* Several minor changes in Makefile.ins and configure.ins, wrt. to the
order of including *.cfg and defining Makefile variables
APPLYING THE PATCH:
patch -p1 < rtems-rc-19990709-4.diff
./autogen
|
|
A bug in acpolish made it into rtems-rc-19990709-0.diff, which
unfortunately affects all Makefile.ins:
* The maintainer mode conditional was erroniously applied to the
dependencies of "Makefile".
In case you already checked in rtems-rc-19990709-0.diff to CVS you have
to check in all Makefile.ins again after applying the patch below :).
Please apply the patch below as follows:
patch -p1 < rtems-rc-19990709-1.diff
tools/update/rtems-polish.sh -ac
Note: There is no need to rerun your tests if you have used
--enable-maintainer-mode to configure RTEMS, because this patch converts
all Makefile.ins to the same settings as used for
--enable-maintainer-mode.
|
|
to move RTEMS more to automake/autoconf and GNU compliance.
Finally, here they are: the "big-patch" patches - merged into one big
patch (~1.5MB).
Sorry for the delay, but testing took much more time than I had expected
- esp. reworking the acpolish script triggered many more tiny issues
than I had expected (cf. below).
At least, now you've got something to spend your weekend with :-.
WARNINGS:
* I've gone a little (??) further than I had announced before.
* Several directories have been moved.
* Several files have been added and removed
* I have tested it with many BSPs/CPUs and a variety of permutiations of
configuration flags, but not with all.
* Most parts of the patch are automatically generated, however there are
many tiny manual modifications.
APPLYING THE PATCH:
./autogen -c
mkdir tools
mv c/src/exec/score/tools tools/cpu
mv c/build-tools tools/build
mv c/update-tools tools/update
patch -p1 -E < rtems-rc-19990709-0.diff
./autogen
If the patch doesn't apply to rtems-cvs, I would suggest that you should
try to apply it brute-force and then to run tools/update/rtems-polish.sh
-ac -am afterwards. A recursive diff between rtems-19990709 + patch and
rtems-cvs + patch then should report only a few dozen significant
changes to configuration files which need to be merged manually (IIRC, I
did not change any source files).
*** Attention: There are files to be removed, moved, copied and added
in/to CVS!
NEWS/CHANGES:
1. Configuration takes place in 3 stages: 1. per host (toplevel
configure script), 2. per target (c/configure), 3. per bsp
c/src/configure automatically triggered from ./configure and
c/Makefile.am.
2. Building of subdirectory c/ takes place in c/$(target_alias) for
cross-targets in c/ for native targets
3. Building of subdirectory c/src takes place in c/${target_alias}/<bsp>
for cross-targets, c/<bsp> for native targets
4. c/build-tools moved to tools/build
5. c/src/exec/score/cpu/tools moved to tools/cpu (=cpu-tools split out)
6. c/update-tools moved to tools/update
7. New subdirectory c/src/make, handles files from make/ on a per BSP
basis
8. Maintainer mode support: Ie. if configuring with
--enable-maintainer-mode disabled (the default), then tracking of many
dependencies will be disabled in Makefiles. Esp. many dependencies for
auto* generated files will be switched off in Makefiles. Ie. if not
using "--enable-maintainer-mode" many auto* generated files will not be
updated automatically, i.e. normal users should not be required to have
auto* tools anymore (untested).
9. Independent configuration scripts for / (toplevel), tools/build,
tools/cpu, tools/update, c/, c/src/, c/src/exec, c/src/lib, c/src/tests,
c/src/make
10. Automake support for all directories above and besides c/src
11. "preinstall" now is implemented as depth-first recursive make target
12. host compiled tools (exception bsp-tools) are accessed in location
in the build tree instead of inside the build-tree when building RTEMS.
13. RTEMS_ROOT and PROJECT_ROOT now point to directories inside the
build-tree - many tiny changes as consequence from this.
14. --with-cross-host support removed (offically announced obsolete by
cygnus)
15. Changing the order of building libraries below c/src/lib/
16. Former toplevel configure script broken into aclocal/*.m4 macros
17. Newlib now detected by configure macros, RTEMS_HAS_NEWLIB removed
from *cfg.
18. sptables.h now generated by autoconf
19. Rules for "mkinstalldirs temporary installation tree" moved from
c/Makefile to subdirectories.
20. Cpu-tools do not get installed.
21. FIX: Use ACLOCAL_AMFLAGS instead of ACLOCAL = -I ... in Makefile.ams
which are in directories with own configure scripts.
22. Hardcoding BSP names into libbsp/.../tools to avoid RTEMS_BSP get
overridden from the environment.
22. FIX: Handling of MP_PIECES in various Makefiles
23. FIX: Removing "::" rules from some Makefile.ins
24. FIX: File permission chaos: (-m 444 and -m 555 vs. -m 644 and -m
755) - Now all include files use -m 644.
25. Removed many gnumake-conditionals in Makefile.ins - Partially
replaced with automake-conditional, partially replaced with
conditionalized Makefile variables (... _yes_V)
26. Massively reworked acpolish: acpolish now parses Makefile.ins and
interprets parts of the Makefile.ins.
27. FIX: Some $(wildcard $(srcdir)/*.h) macros removed / replaced with
explicit lists of files in Makefile.ins.
28. FIX: Replacing MKLIB with RANLIB in Makefile.ins
29. HACK: Add preinstallation for pc386 specific
$(PROJECT_RELEASE)/BootImgs directory
... many more details, I can't recall
KNOWN BUGS:
1. make [debug|profile]_install do not do what they are promissing.
"make [debug|profile] install" does what "make [debug|profile]_install"
has been doing. Proposal: remove [debug|profile]_install
2. Dependencies between temporary installation tree and source tree are
not yet handled correctly.
3. Dependencies between temporary installation tree and source tree are
handled ineffencently (Using INSTALL_CHANGE instead of make
dependencies)
4. RTEMS_ROOT, PROJECT_ROOT, top_builddir, RTEMS_TOPdir now are
redundant.
5. The new configure scripts still are in their infancy. They contain
redundant checks and might still contain bugs, too.
6. RTEMS autoconf Makefile.ins use a mixture of configuration
information gathered in c/$(target_alias)/<bsp>/make and of information
collected from their configure scripts.
7. make dist is not fully functional
8. Subdirectory host-/build-/target- configure options (--target,
--host, --build) do not conform to Cygnus/GNU conventions.
9. Some RTEMS autoconf Makefile.in's makefile targets are not supported
in automake Makefile.ams/ins (e.g. get, clobber).
10. Some automake standard targets are not propagated from toplevel and
c/Makefile.am to autoconf subdirectories (eg. make dist).
11. rpcgen generated files are not part of the source-tree (Automake
conventions favor supplying generated files inside the source-tree,
however there is no support for rpcgen generated files in automake, cf.
yacc/lex support in automake).
12. RTEMS_HAS_RDBG handling is flaky. make/*.cfg use RTEMS_HAS_RDBG per
CPU, while librdb's sources can only be built per BSP. Raises the more
general question whether librdbg located correctly in the source-tree.
13. All make/*cfg files are configured per cpu, currently there is no
location to store per-bsp configuration information --> bsp.cfg, per
aconfig.h?
14. "make install" without having run "make all" beforehand does not
work.
15. handling of --enable-multiprocessing seems to be broken in
make/custom/*
16. Makefile.ins still exploit many gmake features.
17. File permisson chaos on libraries (no explict -m for
libraries/rels/etc).
18. mcp750 Makefiles are broken (Note: I *do* mean buggy - I am not
talking about "not-conforming to conventions", here :-).
19. Dependencies between configure scripts are not handled, eg. aborting
"make RTEMS_BSP=<bsp>" can leave the build-tree in an unusable state.
20. "make clean" does not delete <build-tree>/<bsp>. This is intentional
for now, because rerunning "make" after "make clean" requires an
explicit "make preinstall" afterwards now. This should be done
automatically, but doesn't work in this case for now. To work around
this problem <build-tree>/<bsp> is kept during "make clean" for now
(HACK).
TODO:
1. split out host-compiled bsp-tools
2. Use Cygnus/GNU standards for cross-compiling target-subdir
(CC=CC_FOR_TARGET .. configure --host=${target_alias}
--build=`config.guess'}), to be added to toplevel configure script after
splitting out bsp-tools.
3. Exploit per cpu support directory (c/src/<cpu>)- Splitting out
per-cpu libraries - Are there any?
4. Further automake support
5. Converting subdirectories into standalone / self-contained
subdirectories (Esp. moving their headers to the same common root as
their sources, eg. mv lib/include/rtems++
lib/librtems++/include/rtems++) - This is the main obstacle which
prevents moving further towards automake.
6. Propagating values from *.cfg into Makefiles instead of propagating
them at make time via Makefile-fragments (i.e. try to avoid using
*.cfg).
7. Testing on cygwin host (I *do* expect cygwin specific problems).
8. The ARCH in o-$(ARCH)-$(VARIANT) build-subdirectories is not needed
anymore.
GENERAL ISSUES:
1. Temporary installation tree -- Ian and I seem to disagree basically.
Though I think that I understand his argumentation, I do not share it.
IMO, his way of using the buildtree is mis-using the build-tree, relying
on an inofficial feature of RTEMS's current implementation, which
doesn't even work correctly in the current build-tree, though it
attempts hard to do so. From my very POV, it unnecessarily complicates
the structures of the source- and build-trees. It is not supported by
automake (No automatic generation for the necessary rules) and
complicates the transition to automake significantly (Generating the
rules with an enhanced version of acpolish could be possible).
As Ian correctly pointed out, here a management decision is needed -
though I don't see the need to draw this decision in short terms.
2. preinstallation generally is a sure means to spoil the structure of
the source tree, IMHO (No ranting intended, I am completly serious about
this one). eg. through tree dependencies. The worst problem related to
this I have found in the meantime is bsp_specs. bsp_specs is part of
libbsp, ie. there is *no* way to build *any* part of the source tree
*without* having a BSP *preinstalled*.
Note: This issue is related to issue 1., but is not identical - The
difference is the change of the order make rules have to be triggered.
While preinstallation triggers rules spread all over the source tree
before a "make all" can be run, a temporary installation tree could also
be installed by post "make all" hooks (all-local:, to be run after make
all in a directory is completed) if the directories' dependencies would
be a tree,
3. Stuctural dependencies between subdirectories.
4. Depth of the source tree (Prevents multilibbing and introduces many
unnecessary configure scripts).
5. per cpu vs. per bsp configuration (There are no real per-cpu parts
yets :-).
6. automake does not support $makefiles in AC_OUTPUT. Unlike before, we
now should try to avoid RTEMS_CHECK_MAKEFILE and to hard-code as much
paths to Makefiles as possible.
7. General redesign of the source tree
8. Main installation point - Changing it to ${prefix}/${target_alias}. ?
Besides item 8. (which is a must, IMHO), as far as I see most of them
can not be solved soon and will remain issues in the mid- to long-term
:-.
REMARKS:
* You (as the maintainer) should always use --enable-maintainer-mode
when building RTEMS to ensure that maintainer mode generated files (esp.
those in c/src/make) will be updated when make/* files have changed.
* Use @RTEMS_BSP@ in Makefile.ins and Makefile.ams below c/src/,
$(RTEMS_BSP) or ${RTEMS_BSP} will be overridden from environment
variables when using make RTEMS_BSP="....".
* c/src/make is a temporary cludge until configuration issues are
solved. At the moment it is configured per bsp, but contains
per-target/cpu info only. Its main purpose now is to circumvent
modifying make/*.cfg files, because I consider make/* to be frozen for
backward compatibilty.
* This patch should only affect configuration files. At least I do not
remember having touched any source files.
* To build the bare bsp you now need to mention it in --enable-rtemsbsp.
Example: building gensh1 and sh1/bare simultaneously:
../rtems-rc-19990709-1/configure --target=sh-rtems \
--enable-rtemsbsp="bare gensh1" \

* The next steps in development would be to split out bsp-tools and then
to change to Cygnus/GNU canonicalization conventions for building the c/
subdirectory afterwards (i.e. many standard AC_*.m4 macros could be used
instead of customized versions)
FINAL REMARK:
The issues mentioned in the lists above sound much worser than the
situation actually is. Most of them are not specific to this patch, but
are also valid for the snapshot. I just wrote down what I came across
when working on the patch over the last few weeks.
I wouldn't be too surprised if you don't like the patch at the current
point in development. I am willing to discuss details and problems, I
also have no problem if you would post-pone applying this patch to times
after 4.1, but rejecting it as a whole for all times would be a false
management decision, IMHO.
Therefore I would suggest that you, if your time constaints allow it,
should at least play a little while with this patch to understand what
is going on and before drawing a decision on how to handle this
proposal. I know this patch is neither perfect nor complete, but I
consider it to be a major breakthrough. Don't be anxious because of the
size of the patch, the core of the patch is rather small, the size is
mainly the side effect of some systematic cleanups inside the Makefiles
(result of acpolish).
Feel free to ask if you encounter problems, if you don't understand
something or if you meet bugs - I am far from being perfect and am
prepared to answer them.
Ralf.
