* Patch rtems-rc-20000614-sh.tar.gz from Ralf CorsepiusJoel Sherrill2000-06-141-1/+1
| | | | | | | | | | | | | | | | | | | | | <corsepiu@faw.uni-ulm.de> that migrates the SH port to multilib'ing. This patch involved moving a number of files in the CVS repository, adding new files, and deleting files from their previous location. Ralf gave good instructions (not repeated here) and here are his notes: Note 1: In this version, I did not change the installation points of the headers which are moved inside of the source-tree. This is a temporary hack for not breaking compatibility with 4.5 based BSPs, but will probably not last once having real multilibs (We would have include file conflicts when several BSPs/CPU_MODELS share a common installation prefix). Note 2: I hope not to have broken too much, but I would not be astonished if something goes wrong. Note 3: There are more patches to come :)

| | | | | | | | | | | | | | | | | that contains: * Removes remaining (now illegal) references to $(SRC) from a couple of Makefile.ams * Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in * Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR from most configure scripts, i.e. LIBCDIR becomes less visible) * Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to libbsp/*/configure.ins (A minor bug in previous implementations, which only has an impact when switching to GNU/Cygnus canonicalization) * Cleans up several bogus comments. * Removes MKLIB * Switches the version number to 4.5.0 (for testing version number handling)

* Patch rtems-rc-19991117-4.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-11-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .. a major configuration cleanup ... major enhancement of automake support. ... and it contains a *major* breakthough: Automake support for libchip and libmisc *LEAF* directories. To implement this I have used several nasty tricks * The basical trick is to wrap an old Makefile.in's contents into a Makefile.am and still continue to use (i.e include) the old *.cfg files. * Replaced each INSTALL_IF_CHANGE and INSTALL_VARIANT with make dependencies * Add a gnu-make ifdef AUTOMAKE to main.cfg to avoid conflicts between automake and RTEMS make rules * Replaced each install:: and preinstall:: rule with make dependencies * Replaced SUB_DIRS with SUBDIRS in all Makefile.ins (Automake convention) * Removed each manually added autoconf substitution which automake performs automatically. This is not yet full automake support, because using the temporary installation directory, preinstallation in general and building variants are in contradiction to automake's basic working principles ... ... the new Makefile.ams work still somewhat clumsy ... nevertheless they work (quite well). WARNING: At first glance this patch is small, but * it affects the whole configuration system. * it opens the road to introducing automake to all Makefile.ins currently not being under automake control. JOEL> Does this remove or add any files? Both, all Makefile.ins below libchip and libmisc get replaced with Makefile.ams.
* Patch from "John M. Mills" <jmills@tga.com> with subsequent cleanup fromJoel Sherrill1999-11-186-58/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ralf Corsepius <corsepiu@faw.uni-ulm.de> that adds initial Hitachi SH-2 support to RTEMS. Ralf's comments are: Changes: ------ 1. SH-Port: * Many files renamed. * CONSOLE_DEVNAME and MHZ defines removed from libcpu. * console.c moved to libbsp/sh/shared, build in libbsp/sh/<BSP>/console applying VPATH. * CONSOLE_DEVNAME made BSP-specific, replacement is defined in bsp.h * MHZ define replaced with HZ (extendent resolution) in custom/*.cfg * -DHZ=HZ used in bspstart.c, only * Makefile variable HZ used in bsp-dependent directories only. 2. SH1-Port * clock-driver rewritten to provide better resolution for odd CPU frequencies. This driver is only partially tested on hardware, ie. sightly experimental, but I don't expect severe problems with it. * Polling SCI-driver added. This driver is experimental and completly untested yet. Therefore it is not yet used for the console (/dev/console is still pointing to /dev/null, cf. gensh1/bsp.h). * minor changes to the timer driver * SH1 specific delay()/CPU_delay() now is implemented as a function 3. SH2-Port * Merged * IMO, the code is still in its infancy. Therefore I have interspersed comments (FIXME) it for items which I think John should look after. * sci and console drivers partially rewritten and extended (John, I hope you don't mind). * Copyright notices are not yet adapted

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-08-301-1/+1
| | | | | | | | | | 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.

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-07-266-6/+6
| | | | | | | | | | | | | | | | | | | | | 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.
* This is part of a major patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1999-07-266-130/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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" \ --prefix=/tmp/rtems \ --enable-bare-cpu-cflags='-DMHZ=20 -m1 -DCPU_CONSOLE_DEVNAME=\"/dev/null\"' \ --enable-bare-cpu-model=sh7032 \ --enable-maintainer-mode \ --enable-cxx make make install * 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.

| | | | | | | | | | | | | | This one is an enhancement to acpolish. It replaces some Makefile variables by others variable in Makefile.ins (tries to use unique name for some variables). It therefore eases parsing Makefile.ins for further automatic Makefile.in conversions in future. To apply: cd <rtems-source-tree> sh <path-to>/rtems-rc-19990407-8.sh ./autogen
