New Japanese PO file for 'gcc' (version 4.6.1)
Hello, gentle maintainer. This is a message from the Translation Project robot. A revised PO file for textual domain 'gcc' has been submitted by the Japanese team of translators. The file is available at: http://translationproject.org/latest/gcc/ja.po (This file, 'gcc-4.6.1.ja.po', has just now been sent to you in a separate email.) All other PO files for your package are available in: http://translationproject.org/latest/gcc/ Please consider including all of these in your next release, whether official or a pretest. Whenever you have a new distribution with a new version number ready, containing a newer POT file, please send the URL of that distribution tarball to the address below. The tarball may be just a pretest or a snapshot, it does not even have to compile. It is just used by the translators when they need some extra translation context. The following HTML page has been updated: http://translationproject.org/domain/gcc.html If any question arises, please contact the translation coordinator. Thank you for all your work, The Translation Project robot, in the name of your translation coordinator. coordina...@translationproject.org
Re: [libcpp,lto,fortran PATCH] Fix linemap_add use and remove unnecessary kludge
On Sat, Aug 27, 2011 at 9:04 PM, Dodji Seketeli do...@redhat.com wrote: Hello Richard, Richard Guenther richard.guent...@gmail.com writes: In the LTO FE the two linemap_add calls were to advance the location counter to cover the builtin special locations. You exchange these with only one - that doesn't look correct without more explanation. It seems to me that you don't need to worry about advancing the location counter to cover builtin special locations because the lowest possible location that could be handed out by the line map is set to RESERVED_LOCATION_COUNT. You can see that by looking at linemap_init that sets the initial highest location to RESERVED_LOCATION_COUNT - 1, and at linemap_add that sets the starting location of the added map to the highest location + 1. And RESERVED_LOCATION is set to 2 in line-map.h. Hm, ok. That must have changed since the introduction of LTO then. The LTO bits are ok as well. Thanks, Richard. The PCH change is ok. Thank you. -- Dodji
[PATCH] fix -Werror=maybe-uninitialized in tree-ssa-loop-ivopts.c (PR bootstrap/50218)
The recent r178104 change to tree-ssa-loop-ivopts.c broke bootstrap on i686-linux because stage2 gcc considers the variable 'comp' used but possibly uninitialized, see PR50218.

Hello world, I have just regenerated all but one ofthe files in libgfortran/generated/ after regression-testing. This completed the fix for PR 40866, where I had left out a few files (possibly because of missing dependencies).

C++ PATCH for c++/48582 (core 342: null pointer values as template non-type arguments)
DR 342 allows null pointer values as non-type arguments in C++11; this
patch implements that. We mangle such arguments as a cast from 0 like
the EDG compiler does.
Tested x86_64-pc-linux-gnu, applying to trunk.

[PATCH] Fix ENTRY_VALUE parameter setup in var-tracking (PR debug/50215)
Hi! Depending on the computed hash of the parameter register, corresponding ENTRY_VALUE and the size of the hash table it can sometimes happen that val2 = cselib_lookup_from_insn will actually find val, which means that ENTRY_VALUEs in DEBUG_INSNs will be kept as ENTRY_VALUEs instead of REGs or similar preferrable locations if the value is still live there. Fixed by adding the ENTRY_VALUE to val-loc only after the cselib_lookup_from_insn.

Hi, Ah, now I got you. Hmm, well, I see here no advantage in adding another macro to check for an macro. As in code of libstdc++ there is actual no use for those new ones. To be clear, I didn't personally invent those, but I'm still finding a bit strange doing only for mingw something completely different, considering in particular that the autoconf procedure is run *anyway* on mingw too... Nevertheless, for some error-numbers (eg. EAFNOSUPPORT, EBADMSG, etc) - which are socket API related - there is no constant define in errno.h (and never will be). So code to emulate this would be still a manual thing in error_constants.h header AFAICS (if we plan to support them for mingw targets). Once more, I don't understand: didn't you suggest changing *only* ENOSPC and EPERM? Why are we now discussing other error-numbers like ECHILD, EAFNOSUPPORT and EBADMSG? Are the latter defined in errno.h? In that case, please use [GLIBCXX_CHECK_SYSTEM_ERROR] for now. We can always simplify things at a later time. Paolo.

Hi,
So I altered the patch in the way you were suggesting. I verfied
values supported in more
detail and found that some other error-values should be handled for
mingw host, too.
The feared clash for E2BIG and EOVERFLOW doesn't happen, so I enabled
them, too. Additionally
in combination with winpthread, there are error-values ETIMEDOUT,
ENOTSUP, and EWOULDBLOCK present.

Re: [Fortran, Patch] Coarray: libcaf patch for _gfortran_caf_deregister
On Friday 26 August 2011 08:51:37 Tobias Burnus wrote:
Allocatable coarrays are freed and deregistered via the libcaf function
_gfortran_caf_deregister. Currently, the front end does not generate
calls to the that function, however, this patch already implements the
function.
See http://gcc.gnu.org/wiki/CoarrayLib and
http://gcc.gnu.org/ml/fortran/2010-04/msg00168.html for details.
The function is called with the coarray token as argument. The token
identifies the coarray in a way defined by the library. In case of
single.c, it just contains the address of the allocated memory of the
coarray. In case of mpi.c, it is an array of memory addresses on all
images such that token[this_image()-1] is the memory location of the
current image.
The patch also adds stat= and errmsg= diagnostic.
TODO: Adding calls to the function in code generated by the compiler -
and testing the function.
Tested by compiling with mpicc and gcc with -Wall -Wextra -std=c99.
OK for the trunk?

To be consistent with _gfortran_caf_register, I think you should be freeing
token itself (the whole array).
OK with that change.

Re: [4.7][google]Support for getting CPU type and feature information at run-time. (issue4893046)
Sri, please add a new api to do cpu_indicator initialization on demand
to be used in IFUNC context. Perhaps also add some debug check to make
sure no conflicting cpu model is set.
Ok for google branches for now while the discussion continues.
thanks,
David

Hi,
Thanks for all the comments. I am attaching a new patch
incorporating all of the changes mentioned, mainly :
1) Make __cpu_indicator_init a constructor in libgcc and guard to call
it only once.
2) Add symbol versions.
3) Move all builtins to the i386 port.
4) Add check for atom processor.
5) No separate passes to fold the builtins.
Please let me know what you think.
Thanks,
-Sri.

I don't see any complication.?
Order of constructors. A constructor may call functions
which use __cpu_indicator.
That's why I wrote also:
The initializer function has to be callable from pre-.init contexts, e.g.
ifunc dispatchers.
It obviously has to be guarded against multiple calls. The ctor in libgcc
would be mere convenience because then non-ctor code can rely on the data
being initialized, and only (potential) ctor code has to check and call
the init function on demand.
Ciao,
Michael.
Re: [PATCH][ARM] -m{cpu,tune,arch}=native
On Sat, Aug 27, 2011 at 3:19 AM, Andrew Stubbs a...@codesourcery.com wrote: Hi all, This patch adds support for -mcpu=native, -mtune=native, and -march=native for ARM Linux hosts. So far, it only recognises Cortex-A8 and Cortex-A9, so I really need to find out what the magic part numbers are for other cpus before this patch is complete. I couldn't just find this information listed anywhere. I think there are a lot of clues in the kernel code, but it's hard to mine and it mostly only goes as far the architecture version, not the individual cpu. Could you send linaro-dev@ an email and ask them where this API is documented? Hmm. Should there be a -mfpu=native that picks between soft, VFP, and NEON based on the host? -- Michael
