Linaro QEMU 2011.09 released

by Peter Maydell

The Linaro Toolchain Working Group is pleased to announce the release of Linaro QEMU 2011.09. Linaro QEMU 2011.09 is the latest monthly release of qemu-linaro. Based off upstream (trunk) QEMU, it includes a number of ARM-focused bug fixes and enhancements. New in this month's release: - linux-user mode now supports the 64 bit cmpxchg kernel helpers (only needed for applications compiled for ARMv6 or lower) - PL111 display controller now supported; this fixes a problem where BGR was interpreted as RGB on recent versatilepb kernels Plus a few other minor bug fixes and the usual round of upstream fixes and improvements. Known issues: - The beagle and beaglexm models still do not support USB networking; we intend to fix this for the 2011.10 release - There may be some problems with running multithreaded programs in linux-user mode (LP:823902) The source tarball is available at: https://launchpad.net/qemu-linaro/+milestone/2011.09 Binary builds of this qemu-linaro release are being prepared and will be available shortly for users of Ubuntu. Packages will be in the linaro-maintainers tools ppa: https://launchpad.net/~linaro-maintainers/+archive/tools/ More information on Linaro QEMU is available at: https://launchpad.net/qemu-linaro

arm-eabi-g++: error: unrecognized option '-avoid-version'

by Asa Sandahl

Hi! When building Android with the Linaro toolchain, I encountered this link time error when going from gcc 4.4.3 to gcc 4.6. "arm-eabi-g++: error: unrecognized option '-avoid-version'" I find several posts about people encountering the same thing for different programs. Was this option removed? Anyone know the story behind it? Regards Åsa

Blueprints, Headline and Acceptance criteria for monthly releases

by Mounir Bsaibes

Release Management needs the list of the the blueprints that will be delivered this month. For each bp, they want a Headline and Acceptance criteria. The Headline is a statement to include in the Monthly release announcement. The acceptance criteria is a statement how to verify the work is done. I have collected this month's blueprints in the spreadsheet, please review it for accuracy. If a blueprint you are working on is missing, please add it. The Headline and Acceptance can be added into the whiteboard as follows: Headline: headline text Acceptance: acceptance text Once you add the the headline and acceptance, please modify the spreadsheet to reflect that it is done. https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AoZqvK7R1biJdGxSc… Thanks in advance, Mounir -- Mounir Bsaibes Project Manager Follow Linaro.org: facebook.com/pages/Linaro/155974581091106 http://twitter.com/#!/linaroorg http://www.linaro.org/linaro-blog <http://www.linaro.org/linaro-blog>

by Ramana Radhakrishnan

==GCC== ===Progress=== * Fixed https://bugs.launchpad.net/ubuntu/+source/gcc-4.6/+bug/838994 . Investigated Bernd's alternate patch . Will commit mine. * Looked at PR48308 for sometime whihc might be a dup of PR50313 . * Some blueprint foo. * Committed a few of the outstanding approved patches into Linaro GCC-4.6 * Patch review week * Caught up with email after vacation. === Plans === * Commit conditional compares patch. * Commit the patch for LP838994. * Investigate some of the performance issues with strlen and some of the cases with - one of the ideas is to probably try and get the specific testcases run under u-boot or as a bare-metal binary and look at dumps of various performance monitoring counters and see what's happening. * Look at BRANCH_COST and finish that up next. * Dust off patch for PR19599 . One of them them that has fallen into the cracks. * Some patch review. Meetings: * 1-1s * TCWG calls * Thumb2 performance call. Absences. * 16th Oct (pm) - LLVM developer summit - London * 31st Oct - 4th Nov - Linaro Summit Orlando - Travel booked - hotel to be booked. * 08 Nov - 11 Nov - Tentatively booked not approved. * Dec 19 - 31st Dec - Tentatively booked not approved.

[ACTIVITY] 5th - 11th September

by Andrew Stubbs

Merged both GCC 4.5 and 4.6 from FSF to Linaro. Matthias requested that I avoid a particular upstream 4.6 commit, so I selected the revision before that as the merge point. The problem was then fixes upstream, and another fix was desirable, so I've redone the merge from the branch head. Another widening-multiplies bug was reported to me (I logged it as pr50318/lp843775), so I've fixed that and committed the fix upstream, and filed a merge request on Launchpad. Finished fixing the bugs in my thumb2 constants optimizations, and backported the new patches to Linaro GCC 4.6. Pushed the updated stuff to Launchpad for testing. Richard Sandiford found a flaw in my patch for pr50193/lp836401, so I've done another version of that and posted it upstream. Ramana didn't like that version. I've started again trying to fix it a different way, but I don't have it working just yet. Continued work on my new constant reuse patch. I have it detecting many constant expressions, and calculating the values for some of them. Once it does that sufficiently well, the next step is to track what constants are available where, I then I'll be in a position to find optimization opportunities. At the moment, 'sufficiently well' could just mean MOVW/MOVT pairs, as those are the most common Tried to get the CS Panda Boards up and running again after the move. No success. Ricardo is on the case. I'm still using the boards located at Canonical. Andrew

Continue looking at Richard's micro benchmarks taken from libav w.r.t SMS and experiment with different patches that Richard wrote to improve code generation. Submitted SMS related patch for minor misc fixes http://gcc.gnu.org/ml/gcc-patches/2011-09/msg00551.html Trying to understand why to new version of the patch to support instructions with REG_INC_NOTE in SMS causes bootstrap failure. Will email to the ml regarding it. (http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01216.html)

* Looked at LP bug 736661. Sent a patch upstream. Some positive feedback, but it hasn't been approved or rejected yet. * Looked at the old R_ARM_THM_CALL linker bug, after Matthias prepared a self-contained testcase (thanks). Attached a patch to the bug. Will submit upstream next week if testing goes OK. * Looked at why the backport of lp823708-4.5 retriggered the same bootstrap failure that Chung-Lin's patch did. Haven't been able to reproduce yet. * Looked at making the neon_vget_high/low patterns use ordinary subreg moves. Found that this triggered a fair few latent bugs in the rtl optimisers. Tried to fix those. This gave some nice improvements in some of the libav loops. * Added h264 loops to the libav microbenchmarks. * Blueprints. * Upstream patch review. Richard
