5:09 PM Changeset in rtems [98100d2]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Monstrous patch from Ralf Corsepius <corsepiu@…>. I have made no attempt to divide the comments up and place them with just the appropriate files. 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 Open problems, known bugs, things I didn't do: * custom/p4000.cfg seems to be out of date and requires to be reviewed.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 i3456?86-unknown-freebsd2.12? with i3456?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.

6:42 PM Changeset in rtems [d13b247]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Clean up from Aleksey Romanov (Quality Quorum <qqi@…>). Here are his comments: I removed all unnecessary stuff from start16.s - setting idt and setting 16-bit stack using .code32 istructions.
4:54 PM Changeset in rtems [7252f656]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>

Bare bsp patch from Chris Johns and regenerated files.
4:21 PM Changeset in rtems [43b78f1]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added definition of RTEMSmcpu32p per patch from Robin Kirkham.
4:10 PM Changeset in rtems [924e17a]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Robin Kirkham <Robin.Kirkham@…> to distinguish between CPU32 and CPU32+ cores. Commentary follows: Unfortunately c/src/exec/score/cpu/m68k/m68k.h incorrectly defines M68K_HAS_MISALIGNED for the plain old CPU32 (it is correct for the CPU32+). As a consequence, the recently-relocated m68k memcpy() may still attempt misaligned memory accesses. I suggest that until such time as egcs/gcc differentiates these cores that we invent a new preprocessor symbol, RTEMSmcpu32p for this purpose, on the assumption that egcs may one day grow a -mcpu32+ option which will define a mcpu32p symbol (whether this option would also define mcpu32 is yet to be resolved). BSPs that have a CPU32+ (like gen68360) would for the time being define RTEMSmcpu32p using -D. The symbol is `RTEMSmcpu32p' because symbols of the form xxx should only be defined by the compiler itself. Note that the patch tests for RTEMSmcpu32p *before* mcpu32, since mcpu32 is still defined for the CPU32+. It does not change the gen68360 BSP. An aside: Note that in egcs-1.0.3a, the option -m68332 is identical to -mcpu32, except it defines mc68332 as well as mcpu32. This is only for the sake of compatibility. The story with -m68302 is similar; it defines mc68302 and mc68000. In my opinion these options are depreciated and ought to be avoided in RTEMS.

5:58 PM Changeset in rtems [803de41]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Suggestion from Robin Kirkham <Robin.Kirkham@…> to improve clarity.

Updated.

Jun 23, 1998:

5:42 PM Changeset in rtems [4f0ffa57]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Removed RTS and DTR handling code since the MC68681 seems to only have automatic handling of RTS/CTS. This only protects the on-chip buffers and FIFOs -- not the termios queues as the RTS/CTS code in here did. It may be necessary in the future to enable this automatic support. Interrupt processing code added. In some places, channel and duart base addresses were swapped.
5:40 PM Changeset in rtems [ae21568c]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
New file describing mc68681 libchip driver.

3:54 PM Changeset in rtems [a5d0c7c]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added concept of "mate" -- the other port on the same DUART. This is needed to properly handle the interrupt mask register since it is shared.
2:59 PM Changeset in rtems [b7ebcea]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added close.

Added mc68681 stuff to the makefile. Added numerous constants to mc68681_p.h. Changed spacing. At this point the polled support is in but nothing else is right except the structure.
11:08 AM Changeset in rtems [36152b0e]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Moved get and set register/data typedefs to this file.

9:28 AM Changeset in rtems [cd58d82]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Initial version of these files.

Jun 18, 1998:

7:14 PM Changeset in rtems [ce17a72]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
changed version to 980618
7:05 PM Changeset in rtems [8ed1f8d0]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
New file from Dario Alcocer <alcocer@…>.
7:01 PM Changeset in rtems [cb1b853d]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
All task delete API level services were incorrectly assuming that the task to be deleted was created via the same API (i.e. were of the object class created by this API). For example, a POSIX thread calling the rtems_task_delete(SELF) directive would incorrectly update the RTEMS object local pointer table. Jennifer discovered this when moving tests implemented in C using the Classic RTEMS API into a tree of Ada tests. The Ada tests were implicitly using POSIX services. This lead to some unexpected behavior.
6:58 PM Changeset in rtems [7e4c3d8b]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Modified _Objects_Is_class_valid() to correctly report that 0 was not a valid object class. This was discovered while looking for a bug reported by Jennifer.
3:22 PM Changeset in rtems [9a6994b]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added freebsd support from Dario Alcocer <alcocer@…>.
3:14 PM Changeset in rtems [ce691c51]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Corrected so it returns the correct date. Previously was getting the number of seconds since 1988 from RTEMS and not adding in the 1970-1988 correction factor. Plus removed checks for data/time set since POSIX does not permit this call to fail. GNAT 3.12 depends on this.
3:13 PM Changeset in rtems [bdb1057]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Spacing changes.
3:12 PM Changeset in rtems [ecc9737f]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
