== Minutes ==

* The linaro-toolchain list for toolchain related chatter; please subscribe! * Loic called for sprint topics. See https://wiki.linaro.org/Events/2010-07-PlatformSprint/ToolChainWG * Meetings have been cancelled for the week of the sprint * Mentioned the upcoming hardfp port that Debian is investigating * Port is too large for Linaro itself * Toolchain should support - best place to support, easiest to maintain due to doko * Better choice for Debian as they may get support from Linaro; won't from CSL 2010 Lite edition * Noted that there's disagreement on the Debian triplet and position of the hf marker. Problem is what is correct vs which is the path of least resistance. * ACTION Andrew to propose the triplet change to toolchain upstream? * Noted that the ARM EABI is a family of ABIs that different vendors take variants from * ACTION Andrew to send email to Debian ARM on best triplet * Milestone issue review * ACTION MLH to try perl if no progress is made by pbrook * getfem++ can't be reproduced * vect/* won't fix * mysql fix is ugly * pr9771-1.c MLH to continue or send patch otherwise * neon triggered by march=armv7a which should have occurred with Lucid GCC * Can lower priority if a missed optimisation * MLH wants help on how to best use the packaging system to do what he's used to such as * Build exactly what the Ubuntu PPA will end up as * Build a cross-compiler to try ARM failures on a fast machine * Do an incremental build * Do a non-bootstrap build * Run the compiler under a debugger * Use the test compiler to build a package * ACTION MLH to write up wants * Andrew has a process to build the tarball and will run the certification process afterwards * Loic recommended CSL developers to have local hardware * Blueprints status * Initial 4.4 release reviewed. Done except Ada patch. Andrew to edit whiteboard to note * Update broken Ubuntu patches * Loic suggests reviewing Ubuntu patches month to month * Cross compiler (Marcin) * Tidying up ugly GCC hacks * Stage 1 is now clean * ACTION Marcin to check if xdeb incorrectly produces a package called findutils-armel * ACTION Loic to push changes to mysql * Michael will run Wednesday standup call

Activity reports from preceding week:

= Ulrich Weigand = == GCC ==

* Resolved merge conflicts between cell-branch.diff and gcc444-linaro.diff (investigated and fixed additional autoconf-related build issue) * Investigated bug #602287; resolved as won't-fix for Linaro 4.4 * Started investigating bug #602289

== GDB ==

* Completed build and regression test of GDB 7.2 branch on beagle board * Started working on hardware-breakpoint-support blueprint

== Education ==

* Continued getting familiar with Debian package build process * Continued getting familiar with Launchpad infrastructure * Read ARMv7 Architecture Reference Manual

== Infrastructure ==

* Got remote access to Loic's beagle board * Started process to acquire IGEPv2 board

= Yao Qi = == Linaro GCC ==

* Ubuntu patch ada-acats.diff on linaro gcc 4.4. ada-acats.diff and its dependent patches cause some regression failures. Spent a lot of time on trying different patch sets to linoar gcc 4.4, but failures do go away. Checked the build log of ubuntu gcc, and the same failures are there. We decide to leave this ubuntu patch.

* Merged 19 ubuntu patches to linaro gcc 4.4. Learn bzr push/merge/branch/commit. Very good version control tool, and well-collaborated with launchpad.

* Revert license patch in linaro gcc 4.4.

* Merge CS GCC 4.4 patches to CS GCC 4.5. Choose three patches from Julian's ARM patch list. Two of them are committed into CS GCC 4.5. The third is sent to CS internal review.

== Misc ==

* Some meetings on linaro status.

= Andrew Stubbs = == GCC 4.4 ==

* Continued refining the blueprints. We now have the initial 4.4 toolchain delivery blueprint finalised.

* Entered bugs for each of the test regressions in the Ubuntu GCC vs. FSF GCC.

* Reviewed Yao's launchpad merge request for the Ubuntu GCC patches. It was all good, so I approved the request and did the merge.

* Reviewed the ARM test failures to make sure they were what we anticipated they would be.

* Reviewed some of the Ubuntu patches marked "Needs review". Decided not to use two, rewrote the third and submitted the new patch for review. Matthias has now accepted it, and applied it to Debian also.

* Found out how to create gnu-style release tarballs and wrote a Linaro GCC release procedure document for the wiki. https://wiki.linaro.org/WorkingGroups/ToolChain/GCCReleaseProcess

== GCC 4.5 ==

* Assisted Yao with his patch porting work, and made sure he had things to do.

= Loic Minier =

* Repaired Beagleboard to boot again * Cross-built ncurses; did other xdeb tests * Added color codes and improved structure of https://wiki.linaro.org/WorkingGroups/ToolChain/UbuntuRegressions and https://wiki.linaro.org/WorkingGroups/ToolChain/UbuntuGCCPatches * Discussed armhf port, started http://wiki.debian.org/ArmHardFloatPort * Started sprint planning and associated wiki pages

Bye,
