Russia Host for GCC Archives
Hi. I'm the owner of Russian annual programming contest site http://zcontest.ru The contestants are usually use GCC compiler as their main platform for development. So I decided to put GCC archives on my site. Fell free to post link on it at this page: http://gcc.gnu.org/mirrors.html My site located in Russia, Moscow. The path to archive is: http://zcontest.ru/gcc.php P.S. Looks like, currently, it's the only archive in Russia. -- Best Regards, Roman Solovyev mailto:[EMAIL PROTECTED]
Re: GCC 4.3 target deprecation proposals
Joseph S. Myers wrote: On Thu, 24 Jan 2008, DJ Delorie wrote: At the moment, I'm working on getting sh, h8300, and m32c in shape for 4.3 (or future). I can easily get the test results under 400k by removing some of the multilibs, but I don't think that's a good idea. My sh-elf test tests 38 multilibs, if I only test one that would be a 12k email, which would easily fit past the filters. Are we artificially penalizing targets with many multilibs? If results are being rejected without indicating the target is in terrible shape, you could ask overseers to increase the size limit on gcc-testresults. I'm not actually convinced these long default multilib lists are a good idea; if a user doesn't just want a single multilib for their processor, the long generic list is likely to be wrong for them as well. Depends on the user. For *-rtems*, we build the OS proper multilib and produce libraries. The user links that against a Board Support Package and their application. We are careful to justify each multilib variant in the RTEMS targets since it does lead to longer compile times and longer tool download times when our users install. Here is a count of the multilib variants for the targets we have pre-compiled RTEMS for. Note that all are using gcc 4.2.2 except AVR (4.0.4) and tic4x (3.4.6). arm-rtems4.9 3 avr-rtems4.9 4 bfin-rtems4.9 1 h8300-rtems4.9 7 i386-rtems4.9 6 m68k-rtems4.9 15 mips-rtems4.9 6 powerpc-rtems4.9 15 sh-rtems4.9 11 sparc-rtems4.9 4 tic4x-rtems4.9 4 So you can see that even though we haven't figured out how to run the GCC testsuite when linked against RTEMS, we do have good news on a number of targets. With some help from a gcc tester, we should be able to start reporting results on many of the above using simulators. sh has a mechanism for selecting multilibs at configure time, and a more general such mechanism would be good as well (for some targets such as GNU/Linux, it would need to deal with SYSROOT_SUFFIX_SPEC and SYSROOT_HEADERS_SUFFIX_SPEC as well as the usual multilib variables; note some targets already generate SYSROOT_SUFFIX_SPEC automatically). Also, while I'm not suggesting I be a maintainer for sh and h8300, if I'm working on them and producing test results, should I send them in anyway? I can always stop sending them when I stop working on them (for whatever reason), but meanwhile, does that count against deprecation? Anyone sending results for a target counts against deprecation. I didn't even look at what version the results are for (although maybe in the 4.4 cycle we should only look at results for 4.3 or later). -- Joseph S. Myers [EMAIL PROTECTED]

Sorry. For RTEMS, this just reflects a lack of success in getting the scripts to run with all the magic bits right for an installed cross gcc with extra arguments required to compile and link. If someone familiar with the test suite scripts could help us, we could move on from there to test the SVN trunk on a few RTEMS targets on a regular basis. I manually run the Ada ACATS test suite on at least the SPARC and PowerPC fairly regularly but only report failures by hand. For 4.2.2 the results were near perfect. --joel
Re: [Fwd: Re: FW: matrix linking]
Oliver. Have you got a chance to take a look at the materials? If yes, what do you think on it? Yours sincerely, George. [EMAIL PROTECTED] ?: Thank you for your reply, Oliver. Briefly speaking the solution to the problems you have mentioned looks like this: 1. take a loot at the first picture here: http://docs.georgeshagov.com/twiki/tiki-index.php?page=Matrix+Linking+how+it+works 2. Pointer 1, 2... are vptrs 3. The idea is that each module, library (.so) has a row of vptrs, when it is required to make a dynamic binding this row is going to be copied to the similar one, the new vptrs are applied to the new row of vptrs, the previous, old row is unchanged. Then the shift looks like incremental lock of integer value which is the version of this module (.so). So it means that these threads which execute the code inside the 'old module' they are unchanged, and the new code is going to be executed in case we will have got the new call to the functions of the module. It might have been said it does not answer the question, since there might be some loops which needs to be reloaded also, though I believe it does, since this tends more to the architecture than to linkage already :-) This is quite brief and uncertain explanation. In reality it does not look like this. More details could have been found here: http://docs.georgeshagov.com/twiki/tiki-index.php?page=Matrix+Linking+how+it+works.

[Fwd: Re: FW: matrix linking]
I appreciate your reply, Joe. But I do not think this is off-topic, though. If we are going to discuss the details of your project, Ptolomy, right, then it would have been off-topic, I think. But I'm talking about GCC, therefore I believe this is the right place to post these ideas. What I am trying to say is that there is an additional realization of dynamic binding, which is called matrix linking. There are other's realization of that idea, like Darwin project for instance, but all of these realization has one serious stumbling block which makes their use almost impossible and therefore these realizations have only academic interest, but practically they are useless. And this stumbling block is that you need to 'suspend' the application when you do dynamic binding, moreover you should have all the threads finished inside that code which is going to to re-bind. This is a huge problem. New approach, which I have called Matrix Linking does resolve this problem, it means it becomes possible to make binding right on the fly, without any threads suspending, directly in multi threaded application. I believe this is quite interesting idea in order to be shared with GCC community. I do not think this is a professional reply, saying 'Nothing new here: add a level of indirection...'. I believe the idea has a future, just imagine what opportunities it gives to developer, manager, analyst and clients. I would like the community would have considered the idea. I am ready to answer all the questions you might have. Yours sincerely George. http://docs.georgeshagov.com/twiki/tiki-index.php?page=Matrix+Linking Joe Buck ?: I wrote: Nothing new here: add a level of indirection (or use C++ virtual functions), and dynamically load code. In the Ptolemy project (http://ptolemy.eecs.berkeley.edu/) we were doing that in 1990: we could define new classes and load them into a running application, without restarting.

We're getting off-topic for the list, so I'm answering off-list. The operation could be made thread-safe with appropriate locking (the 15-year-old code did not have this locking, but it's trivial to add). It used the object factory pattern, in which each class has a clone method and there's support for adding a new, dynamically linked class to the master list. If other threads are running and these threads are not in the act of creating new objects from the object factory, they can run in parallel.

Re: core changes for mep port
Guys - what branch/tag are you looking at doing this on? I've been in discussions with Dorit about SPMD utilisation of graphics cards (AMD CTM) which has more inline with parallel asymetric architectures than it does with simple SIMD optimisations. Cheers, Nick. ---Original Message--- From: DJ Delorie [EMAIL PROTECTED] Subject: Re: core changes for mep port Sent: 16 Mar '07 03:09 Do you mean where is the best place to call these functions? Yup. Look at the calls to cgraph_mark_edge in ipa-inline.c There is no such function. I couldn't find anything in ipa-inline that (1) had access to both ends of the call edge, (2) was actually called, and (3) was called before the inlining happened. and look at inline_forbidden_p--there I assume that cfun will hold the caller. cfun holds the callee. I found a lot of functions that only had access to the callee (no help there). I also found lots of functions that looked promising but were never called.

Re: Auto Vectorizing help needed
You'll want to have a look at something like the SSE SIMD optimisation within the back end for the x86. I'd also download the GCC internals document for 4.3.x as it has some information on CPU SIMD optimisations. I've been reviewing this area heavily as I'm combining GCC and GPGPU (the same idea behind Stanford Uni's folding at home GPU client). Looks like I'll have to target the tree before the SIMD vectorisation optimisation area. If anyone's interested - I'm looking to put this all in a white paper and posting up on gpgpu.org forums. ---Original Message--- From: sdutta [EMAIL PROTECTED] Subject: Auto Vectorizing help needed Sent: 24 Feb '07 00:13 I am targeting GCC 4.1.1 to a custom RISC processor; which has some vector instructions (32 bit vectors).

Compile time stack checking
Hi all. I have read the gcc-summit 2005 publication from Eric Botcaczou, Cyrille Comar and Oliver Hainque about static stack analysis. This is a quite interresting approach, especially for embedded systems. While reading the article i saw many talking about ada but not for C. Is the patch only for ada? Will there be a C/C++-Version available someday? I downloaded gcc-4.2.-20060204 and the resulting compiler did not understand -fstack-usage and -fcallgraph-info. A grep on the sources didnt contain the string stack-usage. At least i hoped to find something in the ADA directory, since the gcc online docu regarding GNAT tools already documents that compiler switches. Is there a separate patch to be applied? Kind regards Hauke

This is not a known problem. There have been a lot of patches

I suppose the GameBoy Advance (gba) BSP is your best bet. Instructions
for it are on the Wiki but I personally don't have any experience with
it yet.
There is also the possibility that the SkyEye simulator could be made to
work with the edp7312 BSP but that hasn't been worked through yet.
I'm building up to GCC for arm-rtems4.7 right now.
Did you resolve the issue about the target including a version number?
I also have this arm-rtems specific patch. Something changed after
4.0.x and none of the RTEMS BSPs would link before I added this.

The target is an ep9312 from Cirrus Logic. Even if I didn't manage to compile the edb7312 support, I wanted to read how it was made to try to port RTEMS on ep9312. I think this should be a good study for me. I just had a quick to skyeye and it seems to be based upon armulator which is a target of RTEMS. So, I guess buiding with the armulator bsp should be a good beginning. The armulator BSP doesn't quite initialize memory right. The last I knew, the SkyEye simulator did not run the BSP and no one had investigated. That BSP was developed on real hardware. I would hope the edb7312 BSP would be VERY close to working. --joel

I am not sure I understand how this can happen (I am not familiar at all with the RTEMS build process). If the network functions are available on RTEMS, isn't it the case that corresponding header files should be present as well? If so why aren't they available when you build the Ada runtime library? If not how are these functions made available to applications? You build RTEMS proper after you build the toolset with which you will build it. So when you gcc, you only have access to .h files which are properly associated with libc or libm. Those are provided by newlib. Headers files for networking, most tasking, and other functionality is only available later when you build the OS. To look at it another way, RTEMS doesn't use prebuilt binaries for the run-time libraries when building the tools. We start with a fresh slate every time we build gcc and bootstrap our way up. That way every object on the target is compiled by the same gcc. This lets us get the full benefit of a newer and better gcc every time we update. this patch is needed to make *-rtems compile again. OK to commit? I'd first like to understand what exactly the situation is. I hope the explanation above helps make it clearer. FWIW the extern might be better stylistically outside the function.

I am getting a syntax error with the C front-end but not with the

This is a regression from at least 3.4.0 as 3.3.3 works but 3.4.0 does

cross newlib builds on svn head
Hi, I have been trying to build sparc-rtems4.7 on the head using newlib's head for a few days now. I have finally narrowed the behavior down. If I configure for sparc I am configuring for sparc-rtems4.7 with c and c++, it builds fine. The build process uses xgcc for newlib as one would expect.

Problem building *-rtems on the head
Or at least I think it's the head. I am still learning subversion. :)
I am testing using gcc-head-test with the *-rtems targets. I managed
to build a native compiler and am using that to build the cross
compilers. But when the build gets around to trying to build newlib, it
is using CC=${target}-cc not the xgcc from the built gcc subdirectory.
I am using the same configure command I used with gcc 4.0.x and
including --with-newlib.
Has anyone else tried to build a newlib target from the head recently?

Making a new cross-compile target: where to begin?
Hi, I know that some people are working on a GCC port for Minix v3, but I'd like to work on a cross-compiler for my own purposes. I'd like the host and build to be i686-pc-linux-gnu, and the target to be i[3456]86-pc-minix3. Can anyone give me some advice on where to begin and what info I need? The most obvious issue is that binutils needs to be aware of the Minix 3 a.out object file format, unless I tweak things so that a program that converts statically linked ELF object files into a.out object files runs automatically after a build. I'm not sure what the best approach would be. There are probably some good docs out there on making a new cross-compile target, but I haven't found them. Do they exist, and if yes where are they? What new files do I need to help GCC build for a Minix 3 target, what do I put in them, where can I learn about writing a specs file for Minix 3, etc. Does anyone here have a knowledge of creating a new output object format for binutils? I would guess that I will be patching binutils to accept new command line options, arranging for BFD to write a.out files, and maybe other things. Again, not sure where to begin. I would like to use the GCC 4 series, and binutils 2.16.1+. The goal is to get a cross compiler to build for a Minix 3 system on i3[456]86 systems that runs on a GNU/Linux system, so I can use it to build all sorts of other programs for a Minix 3 system that I can't compile on Minix 3, like most of the GNU programs, as well as the latest Perl and Python, etc, so I can end up with a GNU/Minix 3 system. From there when everything is built, tested and installed, I should be able to use the GNU/Minix 3 system itself to be self-hosting. Thanks for your help. James Buchanan
Re: Making a new cross-compile target: where to begin?
Well, as far as I have seen, most of the internals are documented in the code itself. The best way to learn how it works, in my opinion, is to get a good code cross-reference tool. The files you mostly want to look at are in gcc/config in a build tree. Good luck and have fun, Jonathan Bastien-Filiatrault Maybe a good place to get clues is to look at how GCC and binutils are built for DOS, e.g. DJGPP. (I've asked DJ for some help). Starting with the config stuff for DJGPP will probably help me along. DOS is a similar job to Minix in that it has less facilities than systems like full-blown Unixen. I will try to have fun, after all the blood and sweat parts anyway. :) I'm really eager to learn how all this GCC magic works. James

Except that DJGPP uses COFF, not a.out. DJGPP v1 used a.out, but most of that support has been removed by now. Perhaps I'll be able to get away with --target=i386-aout and simply modifying glibc, newlib or uclibc to use Minix's system calls, and it'll all work with minor tweaks like the specs files GCC uses. I'll try it. I'll post my experiences to the GCC developers' list in case others in future find it useful as a starting point to GNU-ify a new system.

Building of fixincludes with 4.0.1 uses wrong gcc
Dear Sirs, 1. bootstrapping the gcc 4.0.1 under Sparc/Solaris I found that the building in fixincludes uses the gcc (with no PATH specification) instead of the xgcc build by the last stage. It may crash, it happens on my environment, because I've migrated from Solaris 9 to Solaris 10 where the includes are not compatible. The build is: gcc -v Using built-in specs.

Expanding an ADDSI3 into 2 x ADDHI3 does not work
I have a fictitious machine which has a word size of 8-bits but can handle
16-bit adds and 16-bit mov's. I am trying to build the most efficient support
for handling an addsi3 insn. My problem is that if I try to split up the
addsi3 insn into a couple of addhi3 insns (using a define_expand template) the
compiler appears to ignore this declaration and proceeds to implement addsi3 as
a bunch of addqi's along with some carry propogation rtx's. i.e. the compiler
defaults to the word size of the machine and I can't seem to override this.
I could allow it to go and create its big long list of addqi's etc and then use
some insn combining method such as a peephole optimizer but this seems really
inefficient to me - especially when I can explicitly state how a larger insn
should be split.
If I use the following addsi3 template:
(define_insn addsi3
[(set (match_operand:SI 0 general_operand =g)
(plus:SI (match_operand:SI 1 general_operand g)
(match_operand:SI 2 general_operand g)))]
addsi3 %1 %2 %0 ;(%1 plus %2)-%0 )
I can observe addsi being used in the assembly output of my test case.
If I use:
(define_expand addsi
[(set (match_operand:SI 0 general_operand =g)
(plus:SI (match_operand:SI 1 general_operand g)
(match_operand:SI 2 general_operand g)))]
{
emit_insn (gen_addhi3 (custom_subword(operands[0], 0, SImode),
custom_subword(operands[1], 0, SImode),
custom_subword(operands[2], 0, SImode)));
emit_insn (gen_addhi3 (custom_subword(operands[0], 1, SImode),
custom_subword(operands[1], 1, SImode),
custom_subword(operands[2], 1, SImode)));
DONE;
} )
the output becomes a mess of addqi, cmpqi, and branches.
Any help would be great.
Thanks
Marty

No, I just don't build gfortran as a cross. There are many reasons
why this is a bad idea anyway.
Why is something broken in the gfortran build infrastructure?
Assuming not, then it should only be a matter of needed functionality
in the target C library and native FP types. I know gfortran
currently makes assumptions about the FP capabilities of a CPU
and some don't meet that. But there is no reason one should not
be able use an x86 GNU/Linux system to cross build gfortran for
a powerpc or arm GNU/Linux system.

NOT!
Personal gripe.. I still don't know why posting a patch with a PR isn't
sufficient. GCC has two independent systems. Why can't Bugzilla just
forward attachments marked as patches?
Is there anywhere in the GCC problem reporting instructions that says
attaching a patch to a PR is insufficient? I know you don't get that

I don't really think they are the answer here. GNAT has always been
implemented in Ada and has never been buildable without a native Ada

The issue is what VERSION of GNAT is required to compile version X
of GNAT. I don't try to track minimum versions required but in this
case, I think it moved up quite a bit. From install.texi in gcc-4.0.0:

In order to build GNAT, the Ada compiler, you need a working GNAT
compiler (GNAT version 3.14 or later, or GCC version 3.1 or later),
including GNAT tools such as @command{gnatmake} and @command{gnatlink},
since the Ada front end is written in Ada (with some
GNAT-specific extensions), and GNU make.
==
So this could be viewed as only a documentation issue except that
one has to know where to get a binary for GNAT to start the build
process with.
Personally, I have always avoided this by building a native GNAT
first and using that to build the cross-GNAT. It avoids this
issue entirely.
AdaCore has always helped avoid the problem by providing pre-built
binaries for a few platforms. You can use these to kick-start
the process.
Another one I haven't filed yet, is GCC-4.x not correctly propagating
CFLAGS/CFLAGS_FOR_{BUILD|HOST|TARGET} to newlib in one-tree builds (I am
still investigating).
I don't build with newlib either.
I think that's the point -- no one builds all configurations so
everyone has to be very careful to use the right build magic
to keep them all working.
All these to me are strong indications that GCC-4.x has been poorly
tested in cross compilation.
No, just in the configurations you are using.
Possibly. RTEMS may be the only non-GNU/Linux embedded cross target
which tries to stay near the GCC head and is able to reasonably fully
support languages other than C and C++.
The *-elf targets don't have the filesystem and threading support
required to fully support some of the other language run-times.
And since you're not posting the patches you attach to the bugzilla
PRs you open, you're not exactly helping to make things better either.

Just pointing out that if there is a procedure, it doesn't appear to be referenced in all the right places and isn't tied to the PR system. Given the recent discussions of unfriendly responses, what if a new person X found and bug and fixed it, they would file a PR with Bugzilla and most likely attach the patch. And then there is a high probability that someone would not so kindly tell them they hadn't followed a procedure that doesn't appear to be mentioned anywhere they had seen along the obvious path.

Re: GCC 4.1: Buildable on GHz machines only?
Joe Buck wrote: I used to be an embedded programmer myself, and while I cared very much about the size and speed of the embedded code I wound up with, I didn't care at all about being able to run the compiler itself on a machine that wasn't reasonably up to date, much less trying to bootstrap the compiler on an embedded target. Is that really what we should be aiming for? As opposed to just making -Os work really well? If I could get better embedded code by having the compiler use a lot of memory, but I could easily afford a machine with that amount of memory, I would have had no complaint. There are at least three classes of development I have noticed on this thread: (1) self-hosting gcc on slow but traditional hosts (e.g. 68040 UNIX or old Sun's) (2) self-hosted embedded development (e.g. sounds like Peter Barada) (3) embedded development using regular cross-compilation In general all are concerned about lower end CPUs than are used for the mainstream GCC user on GNU/Linux and other UNIces. (1) and (2) are similar and probably have similar requirements. They would like building GCC and running it to be possible on what would be considered low end hardware for main-stream development purposes. (3) is the model for RTEMS, other RTOSes, no-OS targets, and could be the model used by (2). I won't include (1) because they want their systems to be self supporting and users will compile their own code. We are all concerned about the time and memory required to build GCC. But it is a critical concern for (1) and (2) since they are on small hosts. For (3) and RTEMS, it concerns us because the RTEMS Project provides RPMs for 11 targets and tries to include every language we can possibly support (C, C++, Ada, FORTRAN, and Java). I know for the targets that it compiles on, RTEMS works well with C, C++, and Ada. I am unsure about the precise status of RTEMS+Java and FORTRAN is currently up for discussion. Our tool build times are thus very long and when we follow up by building RTEMS and add-on libraries, it gets longer. We struggle to keep up which is why RTEMS reports are sporadic and tend to cluster nearer a release point. It's true that there are many GCC developers who don't care much about embedded systems, but there are others that care a lot. But many GCC developers lack the relevant expertise, I at least do recognize that. And some of the problems the embedded community reports are hard to recognize from native configurations. It therefore seems that we have two *separate* problems: one is that increased resource consumption makes gcc harder to use as a hosted compiler on older systems, and the other is that embedded target support isn't getting the attention it needs (if it weren't for the heroic efforts of Dan Kegel, it would be far worse). We shouldn't mix these two together; it seems sometimes they get mixed solely because too many free software projects don't support cross-compilation properly, but that is a bug in those projects. You are correct. Many free libraries have rough edges when cross-building. One thing that has been on my personal wish list a LONG time is to get RTEMS configurations to properly run the GCC test suite. [I normally test and report against *-elf since they are similar and easier.] Many tests fail or can't run on the NO OS targets because there is assumption of functionality which isn't there. RTEMS supports a RAM filesystem and POSIX threads which make it possible to run more tests than the NO OS targets. For example, the complete Ada validation test suite can be run with near perfect results. Similarly, other languages with run-time requirements which RTEMS can meet. It should be possible to get better quality embedded target results across more languages. The problem is that the RTEMS Project does not have the expertise to do this. We need some help from a DejaGNU/GCC testing expert. Sorry for the length, this is an important issue to me. --joel

Its a 266Mhz ColdFire v4e machine, about 263 BogoMips, 1/20 the BogoMips of my workstation, and with an NFS rootfs, it gets network bound pretty rapidly and runs even slower compared to a NetBSD machine with a local disk :) I would have thought the CPU itself was comparable to or faster than a 68040 or 68060 since they was always at much lower clock speeds. Do you have any local disk or is everything NFS? If so, that would be killer for performance. I remember an old pair of SparcStation 10's we used to have. Network builds vs. local disk was already like 5-10x slower. How much RAM? --joel
Re: GCC 4.1: Buildable on GHz machines only?
Peter Barada wrote: Well, yes. 1 second/file is still slow! I want make to complete instantaneously! Don't you? Actually I want it to complete before I even start, but I don't want to get too greedy. :) What's really sad is that for cross-compilation of the toolchain, we have to repeat a few steps (build gcc twice, build glibc twice) because glibc and gcc assume that a near-complete environment is available(such as gcc needing headers, and glibc needing -lgcc-eh), so even really fast machines(2.4Ghz P4) take an hour to do a cross-build from scratch. That sounds comparable to the time required to build RTEMS toolsets. I just looked at the timestamp on the build logs for a gcc 4.0.0 CVS build with newlib 1.13.0 and it is on the order of 60-90 minutes per target on a 2.4 Ghz P4 w/512 MB RAM. This is just C and C++ and the variance is probably mostly due to the number of multilibs. I checked build logs of gcc 3.3.5 with newlib 1.13 from December on the same machine and times were comparable so it isn't a recent slowdown. When I built my native 4.0.0 on this machine, I did notice that compiling the Java libraries took long enough to notice and when I did a top, I noticed that gjc was running for 30+ seconds of CPU time with RSS on the order of 150 MB. Another time I noticed that sh had taken 90 seconds and that was an invocation of libtool with a very long command line. Here is the configure command and output of time on this machine for a gcc 4.0.0 build: ../gcc-4.0.0/configure --prefix=/opt/gcc-4.0.0 --enable-languages=c,c++,ada,java,objc 4271.94user 685.49system 1:31:18elapsed 90%CPU (0avgtext+0avgdata 0maxresident)k0inputs+0outputs (33176183major+40970199minor)pagefaults 0swaps A 2.4 Ghz P4 isn't what I would consider an obsolete machine and it took 90 minutes for make -- not a full bootstrap. --joel

Re: Patches for coldfire v4e
[EMAIL PROTECTED] wrote: Hi, Attached are the patches for coldfire v4e. These changes are originally contributed by Peter Barada. I have migrated and tested these changes from gcc 3.04 to gcc 3.4 and now to mainline. Since coldfire v4e has MMU we need to support m68k-linux target for coldfire v4e. To support m68k-linux for coldfire v4e I need to modify t-linux. But I suppose this is not desirable. In that case we might have to create another target, maybe coldfire-linux. Please give your comments/suggestions on this. Is it ok to modify t-linux or coldfire-linux should be created. How many multilib's does adding the v4e support add? I hate to see another entire toolset binary just to get 1 or 2 multilib variants. GNU/Linux is not the only OS interested in the v4e. There should be a generic elf target (m68k-elf) and I know the RTEMS community would like this (m68k-rtems). It might make sense to add the multilib to the t-* files of interest and add coldfire-XXX targets for smaller dedicated toolsets. It shouldn't be much besides a new t-XXX file and a config.gcc entry if you can get binutils and gdb to match. Thanks and Best Regards, C Jaiprakash __ Do you Yahoo!? Yahoo!
