 I've not seen anyone approve it yet.  I'm not a maintainer for that area, so, 
 I cannot.

Who can approve it?  Looking at the maintainers file it's not clear to

Hi,

Please consider this patch to stddef.h. GNU/kFreeBSD has the same

 Looks good.  However, Rainer's in the middle of moving things from gcc/
 to libgcc/ -- where they belong -- and committing a new port now would
 interfere with that.  If it's OK, I'd like to hold off applying this
 until Rainer's finished his changes.
 I'm in the middle of moving shlib support (another day), need to rebase
 crtstuff and libgcc1, and finish libgcc2.

My patch still applies cleanly to current HEAD, has this migration
happened already?  If not, what's the current ETA?  I'll have almost
no spare time after this week, I'd like to sort this out before/during
the weekend if possible.

Thanks!

[PATCH] split mips/gnu-user.h from mips/linux.h

[Robert Millan]

Hi!

This patch splits those bits from:

config/mips/linux.h
config/mips/linux64.h

which are applicable to GNU userland, into:

config/mips/gnu-user.h
config/mips/gnu-user64

respectively.  It is analogous to the split that was performed for
config/i386/* by Joseph Myers in r172271.

I've verified that my patch doesn't cause any regression (resulting
gcc/xgcc is identical both for mips-*-linux and mips64*-linux).

Re: [PATCH] split mips/gnu-user.h from mips/linux.h

[Robert Millan]

Hi Richard,

Thanks for committing!  Just one small note:

2011/7/19 Richard Sandiford rdsandif...@googlemail.com:
 needs to deal with linux64.h as well.  I also kept the copyright notice
 the same on linux.h (even though it's only a one-liner now).

 Applied with those changes, thanks.

It's probably harmless, but with this change if --enable-targets=all
is used, then mips/gnu-user.h is included twice.  The second one can
be removed.

This patch for AMD64 targets running GNU/kFreeBSD has been approved

PING^4 APPROVED patch for AMD64 targets running GNU/kFreeBSD, anyone?

[Robert Millan]

This patch for AMD64 targets running GNU/kFreeBSD has been approved
already, would anyone be so kind to commit it?  I'm afraid I don't have
write perms currently.

See: http://gcc.gnu.org/ml/gcc-patches/2011-06/msg00884.html

Thank you very much :-)

PING^3 [PATCH] Support for AMD64 targets running GNU/kFreeBSD

[Robert Millan]

Please someone look at this if you have time.  The patch is very small now.

2011/6/3 Robert Millan r...@gnu.org:
 Actually, please consider this patch instead.  It's the same but fixes a
 mistake in ld.so pathname.

 2011/6/2 Robert Millan r...@gnu.org:
 Hi,

 2011/5/21 Joseph S. Myers jos...@codesourcery.com:
 Please send a patch against *current trunk* and CC *relevant target
 architecture maintainers*.  linux*.h headers are no longer used on
 non-Linux targets (since my 2011-04-28 patch - on which I CC:ed you) so
 this patch version is no longer appropriate.  I think you'll want to make
 gnu-user64.h use GNU_USER_LINK_EMULATION32 and GNU_USER_LINK_EMULATION64
 similarly to how gnu-user.h uses GNU_USER_LINK_EMULATION.

 Thanks for the tip.  Here's an update to current trunk.

PING^2 [PATCH] Support for AMD64 targets running GNU/kFreeBSD

[Robert Millan]

Please can this patch be considered? It's several months old (sent in
Jan 2011), and it is critical to use of GCC on GNU/kFreeBSD.

2011/1/26 Robert Millan r...@gnu.org:
 Ping!

 2011/1/18 Robert Millan r...@gnu.org:
 2011/1/14 Robert Millan r...@gnu.org:
 2011/1/12 Robert Millan r...@gnu.org:
 * The headers config/kfreebsd-gnu.h etc. override
  GLIBC_DYNAMIC_LINKER.  But the 64-bit configurations
  x86_64-*-kfreebsd*-gnu and x86_64-*-knetbsd*-gnu do not appear to
  use any header that would override GLIBC_DYNAMIC_LINKER32 and
  GLIBC_DYNAMIC_LINKER64, which are what LINK_SPEC in linux64.h
  actually uses.  Thus those configurations would use Linux-specific
  dynamic linker settings, which seems unlikely to be as intended.

 It's not as intended. On amd64 we use /lib/ld.so.1 and
 /lib/ld-kfreebsd-x86-64.so.1.

 It seems x86_64-kfreebsd-gnu has been broken for a while.  I
 just realized that I wrote a patch to fix this in 2006 [1], but
 somehow it was never merged in GCC (actually I'm not even
 sure I submitted it).

 In the meantime Debian GNU/kFreeBSD has been using this
 patch to build GCC on their kfreebsd-amd64 port.

 I can prepare an updated version of this patch (relative to
 trunk + your linux.h overhaul [2]).

 Here is it.

Re: kfreebsd-gnu etc. issues

[Robert Millan]

2011/1/12 Robert Millan r...@gnu.org:
 * The headers config/kfreebsd-gnu.h etc. override
  GLIBC_DYNAMIC_LINKER.  But the 64-bit configurations
  x86_64-*-kfreebsd*-gnu and x86_64-*-knetbsd*-gnu do not appear to
  use any header that would override GLIBC_DYNAMIC_LINKER32 and
  GLIBC_DYNAMIC_LINKER64, which are what LINK_SPEC in linux64.h
  actually uses.  Thus those configurations would use Linux-specific
  dynamic linker settings, which seems unlikely to be as intended.

 It's not as intended. On amd64 we use /lib/ld.so.1 and
 /lib/ld-kfreebsd-x86-64.so.1.

It seems x86_64-kfreebsd-gnu has been broken for a while.  I
just realized that I wrote a patch to fix this in 2006 [1], but
somehow it was never merged in GCC (actually I'm not even
sure I submitted it).

In the meantime Debian GNU/kFreeBSD has been using this
patch to build GCC on their kfreebsd-amd64 port.

I can prepare an updated version of this patch (relative to
trunk + your linux.h overhaul [2]).

2011/1/12 Ian Lance Taylor i...@google.com:
 All that said, I see little harm in using a PT_GNU_STACK header on
 binaries even if the kernel does not fully support them.  Except for the
 small amount of wasted space in every .o file and every executable, but
 I lost that argument years ago.

Thanks Ian.  Seeing that there's so little harm in enabling it
gratuitously, I think it'd be best to assume that PT_GNU_STACK
is supported unless someone can prove otherwise.

 I don't understand this code, but what I can do is confirm that disabling

 this be ok?

 That makes sense to me.

Confirmed, linux-unwind.h can be removed.

 If disabled for non-Linux-kernel targets, the
 REG_NAME abstraction may as well be removed as not actually being useful
 at present.

Ack.  I'll send a patch for this.

Re: kfreebsd-gnu etc. issues

[Robert Millan]

2011/1/12 Joseph S. Myers jos...@codesourcery.com:
 I don't think they are necessarily broken - and if they are, it is because
 of Linux-specific headers being used in non-Linux-specific code, not the
 other way round.

Actually, it's a different problem.  I'll just prepare a patch and
send it, it'll be obvious by reading the patch.

 So if you could clarify the answers to my questions regarding
 PT_GNU_STACK and signal frames for those targets (with or without fixing
 any bugs for those targets indicated by the answers to those questions),
 that would help determine the correct division of those headers.

Ok, I'll answer what I can in your previous mail.

Re: kfreebsd-gnu etc. issues

[Robert Millan]

2011/1/1 Joseph S. Myers jos...@codesourcery.com:
 [...] I found
 several possible problems with the configurations for *-kfreebsd-gnu,
 *-knetbsd-gnu and *-kopensolaris-gnu.

Ok.  Unless indicated otherwise, my answers below apply to
*-kfreebsd-gnu, which is the only in these 3 systems that is
actively maintained.

For the other two I wouldn't worry about either guessing or
leaving them as-is.  If minor breakage happens it's unlikely
to bother anyone.

 * The headers config/kfreebsd-gnu.h etc. override
  GLIBC_DYNAMIC_LINKER.  But the 64-bit configurations
  x86_64-*-kfreebsd*-gnu and x86_64-*-knetbsd*-gnu do not appear to
  use any header that would override GLIBC_DYNAMIC_LINKER32 and
  GLIBC_DYNAMIC_LINKER64, which are what LINK_SPEC in linux64.h
  actually uses.  Thus those configurations would use Linux-specific
  dynamic linker settings, which seems unlikely to be as intended.

It's not as intended. On amd64 we use /lib/ld.so.1 and
/lib/ld-kfreebsd-x86-64.so.1.

 * These configurations use file_end_indicate_exec_stack to use the
  PT_GNU_STACK convention.  While some of the implementation of this
  is in the GNU linker and glibc, it also requires kernel support for
  correct operation.  Do all these kernels support this convention, or
  should this code actually be disabled for them in GCC and glibc?

I'm not familiar with PT_GNU_STACK.  Does a working
_dl_make_stack_executable() in glibc [1] indicate it's supported?

[1] 
http://svn.debian.org/viewsvn/glibc-bsd/trunk/glibc-ports/kfreebsd/dl-execstack.c?revision=1685view=markup

 * The kfreebsd-gnu and knetbsd-gnu configurations use linux-unwind.h
  (kopensolaris-gnu disables this).  They define REG_NAME to adapt
  linux-unwind.h to their system headers.  But linux-unwind.h also
  contains hardcoded checks for the particular instructions, complete
  with hardcoded Linux syscall numbers, in Linux signal trampolines.

I'm sorry.  It seems this would be my fault (I introduced this with
the first kfreebsd-gnu port).

  Do the FreeBSD and NetBSD kernels really use identical instructions?

Definitely not.  But it's strange we didn't notice, we've been using
it for several years.

  Does this code do anything useful on those systems?  If it's useful
  (possibly with some fixes) then linux-unwind.h ought to be renamed;

The only thing I know for sure is that those 2 syscalls don't work. Is
there any possibility that linux-unwind.h is useful for GNU/kFreeBSD
in its current state?

I don't understand this code, but what I can do is confirm that disabling
linux-unwind.h doesn't cause any breakage.  Then we could disable it
untill/unless someone more clued than me ports it to kFreeBSD.  Would
this be ok?

 * A minor point: TARGET_VERSION, referring to Linux, is not overridden
  by these configurations.

Perhaps a common (or a fallback) string mentioning GNU and/or glibc
would fit.  But where's this displayed anyway?

Re: kfreebsd-gnu etc. issues

[Robert Millan]

Hi Joseph

I'll look at more detail at the other problems, but first it
seems that non-Linux GNU targets are currently broken
because many declarations that are not Linux-specific
have been added to the Linux-specific sections of
config.gcc.

Should I wait untill your patch is merged to fix this?

Btw, your patch overhauls linux.h but not i386/linux64.h
which is in the same situation as you described.

Re: kfreebsd-gnu etc. issues

Hi Joseph,

2011/1/1 Joseph S. Myers jos...@codesourcery.com:
 I'm trying to stop non-Linux GCC targets from using config/linux.h and
 other headers whose names indicate they relate to the Linux kernel,
 separating GNU-userspace and Linux-kernel configuration more cleanly.
 http://gcc.gnu.org/ml/gcc-patches/2010-12/msg02055.html is the
 initial patch in this series, and in the course of working on the
 corresponding changes for i386/linux.h and i386/linux64.h

Thank you for doing this.  As the person who introduced this
kind of use, I intended to propose something along these
lines myself, but never got the time to do it.

 I found
 several possible problems with the configurations for *-kfreebsd-gnu,
 *-knetbsd-gnu and *-kopensolaris-gnu.

Re: RFC: Add 32bit x86-64 support to binutils

Hi folks,

I had this unsubmitted patch in my local filesystem.  It makes Linux
detect ELF32 AMD64 binaries and sets a flag to restrict them to
32-bit address space.

It's not rocket science but can save you some work in case you
haven't implemented this already.

Best regards

 Proposals for gcc extensions are always welcome.  A C# frontend would
 be interesting, though there might be some patent considerations.

That's where I think it gets interesting.  If Microsoft or its partners came to
distribute it, they would be implicitly issuing a public grant of the patents
covering it (as per GPL section 11).

 However, I think a C# frontend would be too much work for one student
 during the summer.

Do you think it can be broken down?  My understanding of compilers is very
narrow (although I expect to improve it at some point).

Maybe a subset of the syntax could be defined by a set of test cases?

 FWIW there is an incomplete CIL front end on a branch.  See:
 
 http://gcc.gnu.org/projects/cli.html
 
 Based on experience with gcj I would say that it is just fine to write
 a front end this way, and do C#-CIL translation in a separate
 program.
 
 I agree with Ian that this is too big for a SoC project.

I'll check that up, thanks for the pointers.
