* Towards automake XI patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-03-19114-362/+1351
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is the most scary of all proposals I've been mailing to you this week until now. It consists of 3 parts: 1. a patch 2. a perl script (acpolish) 3. a shell script wrapper to invoke the perl-script. The perl-script reads in each Makefile.in and modifies them ("polishes/beautifies" them :-). These modifications are not easy to describe: Basically, it hard-codes some automake Makefile-variables and rules into RTEMS autoconf-Makefile.ins (Note: autoconf vs. automake!!) and converts some settings/variables to configure scripts' requirements (Yes, plural). E.g. it adds the automake standard variables $top_builddir and $subdir, adds dependency rules for automatic re-generation of Makefiles from Makefile.in, adds support variables for relative paths to multiple configure scripts etc. The patch is a one-line patch to enable the support of the new features added by acpolish. The shell script is a wrapper which pokes around inside of the source tree for Makefile.ins and invokes acpolish on all autoconf-Makefile.ins. acpolish is designed to be able to run several times on the same Makefile.in and may once become a more general tool to convert RTEMS Makefile.in to automake. Therefore, I'd like to keep it inside of source tree. (e.g. as contrib/acpolish or c/update-tools/acpolish). However, it doesn't make sense to export it outside of RTEMS. To apply this: cd <source-tree> patch -p1 -E < <path-to-patch>/rtems-rc-19990318-1.diff tar xzvf <path-to>/rtems-rc-polish.tar.gz ./rtems-polish.sh ./autogen Note: The path contrib/acpolish is hard-coded into rtems-polish.sh, if you decide to put it in an alternative place, please modify rtems-polish.sh to reflect this change. Later: cvs rm make/rtems.cfg (It isn't used anymore) cvs add contrib cvs add contrib/acpolish cvs commit I've tested this intensively, but naturally I can't exclude bugs. Ralf. PS.: Most probably, this is the last "Towards automake" patch. The next one probably will be a real automake patch.
* Towards automake X patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-03-1913-0/+65
| | | | | | | | | | | | | | | | | | | This one once again changes the scheme to preinstall bsp_specs. It moves generating PROJECT_ROOT/lib/bsp_specs to libbsp/<cpu>/<bsp>/wrapup/Makefile.in. I.e. it decentralizes generation of bsp_specs to a bsp-dependent directory, because preinstalling bsp_specs in a centralized Makefile like it has been done until now does not harmonize well with spliting the toplevel configure script in cpu and bsp-dependent configure scripts and automake. First apply the patch (rtems-rc-19990318-0.diff) below, then run the reorg-bsp_specs.sh script. IMO, this one is comparatively harmless and eases automake support significantly.

| | | | | | | | | | | problems that prevented the 19990302 snapshot from running on the efi332. I'm happy to report that rtems-19990302 is running on the efi332 board. I have enclosed a few minor patches below to the efi332 bsp. All patches are within that library but one. make/custom/efi332.cfg has a patch to select the right CPU_CFLAGS (at one time -m68332 was a problem... -mcpu32 or -m68332 work fine now).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | FP issues on this target: The default variants of libc, libm and libgcc assume that a 68881 coprocessor is present. Without the FPSP, any floating point operation, including printf() with a "%f" format specifier, is likely to cause an unimplemented instruction exception. The FPSP works with the default variants of libc, libm and libgcc. It does not work in conjunction with the msoft-float variants. The paranoia test goes into an infinite loop at milestone 40. I am guessing that floor() is returning an incorrect value. The msoft-float variants of libc, libm and libgcc appear to do floating point I/O properly. They only failed in paranoia. Offhand, I can't think of why they would conflict with the FPSP, so I think that there is something wrong with the msoft-float code. It might be my installation. Given my experiences, I decided to install the FPSP in bsp_start(), and to link against the default variants of libc, libm and libgcc. This causes the executables to increase in size by about 60 KB. The README file and the mvme167.cfg specify how to remove the FPSP, and how to link against the msoft-float variants of the libraries. This is not what Eric Norum had done: on my host, his gen68360_040 port links RTEMS code with the msoft-float variants of libc and libm, and the default variant of libgcc. In this configuration, the output of printf() with "%f" is garbage on my target.

Here is an excerpt from Ralf's email: Changes including comments on changes I made after cycling through all the targets: * Added ranlib support. Now all targets use "ranlib" instead of "ar -s" to build an index for a library. If ranlib isn't detected during configuration, check if ar -s is working and try "ar -s" instead of * Removed $(XXX_FOR_TARGET) from make/target.cfg.in, use $(XXX) instead now. * gcc-target-default.cfg: LINK_XXXX-defines reworked to solve the -l problem under posix (cf gcc-target-default.cfg) * rtems-glom replaced by Makefile-rules inside of the wrapup/Makefile.in that has been using rtems-glom until now. * Removed CCC and friends in gcc-target-default.cfg, as they have been breaking CXX support. * Removed CONFIG.$(TARGET_ARCH).CC lines from several custom/*.cfg files, because this is now set in custom/default.cfg. * Added aclocal/ar-s.m4, check whether "ar -s" is working * Added aclocal/cygwin.m4 and aclocal/exeext.m4. * Reworked aclocal/canonicalize-tools.m4: Added ar -s check; fixes for problems when XXX_FOR_TARGET is given via environment variables (didn't work for gcc until now), adding cygwin check, improved autoconf-cache handling. * Removed -l from make rule dependencies. LINK_LIBS is now allowed to contain -L and -l. LINK_OBJS and LINK_FILES must not contain -L or -l. gcc28 make-exe rules now link using $(LINK_OBJS) $(LINK_LIBS) => Almost all custom/*.cfg are modified. This is very likely to break something because of typos or having missed to edit a file. Open problems, known bugs, things I didn't do: * custom/p4000.cfg seems to be out of date and requires to be reviewed. (JRS NOTE: It is subordinate p4650 and p4600 -- both of which build ok after minor changes.) * custom/psim.cfg needs to be reviewed, I added some changes to it, I am insecure about. (JRS NOTE: psim had a minor problem endif/endef swapped but runs fine.) * rtems-glom.in can now be removed. * gcc*.cfg files "make depend" rules don't honor language specific flags (e.g CXXFLAGS is ignored for *.cc) - Nothing to worry about now, but may cause problems for hosts/targets not using gcc or rtems-add-ons that use external packages. * AFAIS, the no_bsp BSP can't be build anymore, i.e. configure refused to configure for it whatever I tried. * The toplevel and toplevel+1 README files are quite out-dated * cygwin.m4 isn't of much use for rtems. In most cases (cf. aclocal/*.m4) it is worked around by directly using $host_os. I think I'll remove it soon after the next snapshot * Before release the cygwin patch needs to be tested under cygwin. I may have broken/missed something (esp. the sed-pattern to convert \\ into / may be broken). * You should try to build/run the posix-BSP under solaris - I don't expect problems, but I am not 100% sure, esp. with regard to ranlib/ar -s. * You should consider to convert all make/compilers/*.cfg files into make/compilers/*.cfg.in files and let autoconf generate the *.cfg. This may help getting rid of some if/then/else statements and help hard-coding some defines into those files in future and shouldn't disturb now. * Not having installed libc.a/libm.a on a host may still break building rtems, esp. when using -disable-gcc28 as the gcc27-configuration scheme directly accesses libc.a and libm.a. The problem should not appear when using gcc28 because it references libc/libm only through -lc and -lm which may be static or dynamic (I didn't test this). * shgen is not yet included (I didn't yet have enough time to integrate it). * I know about a few more configure-probs (esp. cross-checking --enable-* flags). + warn/refuse to configure when --enable-libcdir and --enable-gcc28 are given. + force --enable-libcdir when --disable-gcc28 is given * Replaced KSHELL with @KSH@ in some shell scripts generated by configure.in. * Added a dependency to aclocal/*.m4 in the toplevel Makefile => configure and aclocal.m4 will now be rebuild when any aclocal/*.m4 file is changed * Some changes to aclocal/gcc-pipe.m4 and aclocal/gcc-specs.m4 * Replaced i[[3456]]86-unknown-freebsd2.[[12]] with i[[3456]]86-*freebsd2.* in configure.in, as I suppose there might exist a variety of valid vendors (2nd field of the name-tripple) * Disabled override MAKEFLAGS in toplevel Makefile.in - Potential side-effects are not really clear to me. * In mvme162.cfg, $(LINK_LIBS) is missing in the CC line in gcc28's make-exe rule (yet another one I missed to edit). Just append $(LINK_LIBS) to the "CC" line, like I hopefully did to ALL other custom/*.cfg files. * the problem with mvme162lx.cfg is a follow-up problem of the mvme162.cfg-bug. * mvme162/console and idp/console had variables named Buffer which conflicted with similarly named variables in some tests.

* Numerous changes which in total greatly reduced the amount of sourceJoel Sherrill1998-04-1522-339/+1
| | | | | | | | | | | | code in each BSP's bspstart.c. These changes were: + confdefs.h now knows libio's semaphore requirements + shared/main.c now copies Configuration to BSP_Configuration + shared/main.c fills in the Cpu_table with default values This removed the need for rtems_libio_config() and the constant BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open files can now be set on the gcc command line.
* Transitioned to shared bsp_libc_init() and cleaned up comments.Joel Sherrill1998-04-1522-533/+223
|
* Per suggestion from Eric Norum, went from one initial extension setJoel Sherrill1998-04-1511-142/+0
| | | | | | to multiple. This lets the stack check extension be installed at system initialization time and avoids the BSP having to even know about its existence.

* Switch to using a shared main() for all of the embedded BSPsJoel Sherrill1998-03-2134-235/+66
| | | | | | | | based on the GNU tools. This usually involved correcting the type of bsp_start(), bsp_cleanup(), adjusting the start code to call the right start routine (the shared boot_card()), and then removing code from bsp_start() which was performed in the new boot_card()/main() path.
* Fixed typo.Joel Sherrill1998-03-201-1/+1
