First proposals

by Michael Hope

Hi Åsa. Well, the first proposals have arrived. I've cc'ed this to linaro-toolchain so we have a record. First, visit: http://ex.seabright.co.nz/helpers/proposals and see there are new merge requests from Ulrich with new results. Next, login: http://ex.seabright.co.nz/helpers/login Your login is your Launchpad OpenID login "https://launchpad.net/~asa-sandahl" After logging in, go back to the proposals page. See that the fwprop-subreg merge request has a i686 and x86_64 result. The i686 one is fine so click 'Record' and follow your nose. The x86_64 is interesting - the fault might be real. Click 'Record'. Note the subject line has 'regressed' in it. Ulrich will have to investigate. The lp-879725 results look fine so record both of those. Scanning down the page shows that everything else is recorded so you're done! The tool is a bit slow so don't be surprised if an operation takes ~10 s. The tool is backed by a cache so you won't see the results for ~2 hours. -- Michael

Next week

by Andrew Stubbs

Hi Michael, I can't remember if I told you before, but I shall be away at the CodeSourcery (Ok, Mentor Graphics's ESD TOOLS) annual meeting most of next week. I ought to be back at work on Friday. In the meantime I shall be reading email, but not spending much time on Linaro work. I can probably still get the GCC release process done, but if you'd prefer Ramana did it this month then that's fine with me. Andrew

Backporting A15 changes

by Michael Hope

Hi there. Linaro is about what's next and, as part of this, we should backport any reasonable Cortex-A15 changes to our 4.6 branch. Richard and Matthew, could you let us know directly when new patches from ARM land upstream? We're already doing this but I thought I'd say it out loud. -- Michael

Building Linaro GCC from source

by Javier Martinez Canillas

Hello, I'm trying to build the Linaro GCC from source on an x86_64 Fedora 16 box. I'm using as a guide a wiki entry I found in linaro.org site [1] that explains how to build a native version of the compiler. But instead of a native version I want to be able to cross-compile ARM binaries for my target machine. This is what I tried: [javier@munra src]$ wget -c http://launchpadlibrarian.net/86993387/gcc-linaro-4.6-2011.12.tar.bz2 [javier@munra src]$ tar xaf gcc-linaro-4.6-2011.12.tar.bz2 [javier@munra src]$ mkdir build && cd build [javier@munra build]$ ../gcc-linaro-4.6-2011.12/configure --target=arm-linux --disable-bootstrap --enable-languages=c --prefix=/home/javier/tools [javier@munra build]$ make -j4 && make install But got this error: make[2]: Leaving directory `/home/javier/src/build/gcc' Checking multilib configuration for libgcc... mkdir -p -- arm-linux/libgcc Configuring in arm-linux/libgcc configure: creating cache ./config.cache checking for --enable-version-specific-runtime-libs... no checking for a BSD-compatible install... /usr/bin/install -c checking for gawk... gawk checking build system type... x86_64-unknown-linux-gnu checking host system type... arm-unknown-linux-gnu checking for arm-linux-ar... arm-linux-ar checking for arm-linux-lipo... arm-linux-lipo checking for arm-linux-nm... /home/javier/src/build/./gcc/nm checking for arm-linux-ranlib... arm-linux-ranlib checking for arm-linux-strip... arm-linux-strip checking whether ln -s works... yes checking for arm-linux-gcc... /home/javier/src/build/./gcc/xgcc -B/home/javier/src/build/./gcc/ -B/home/javier/tools/arm-linux/bin/ -B/home/javier/tools/arm-linux/lib/ -isystem /home/javier/tools/arm-linux/include -isystem /home/javier/tools/arm-linux/sys-include checking for suffix of object files... configure: error: in `/home/javier/src/build/arm-linux/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[1]: *** [configure-target-libgcc] Error 1 make[1]: Leaving directory `/home/javier/src/build' make: *** [all] Error 2 Before trying to compile I've installed the libgmp, libmpfr and arm cross tool-chain [2] Fedora packages so I guess all gcc dependencies are met (binutils, glibc, etc). Could someone be so kind to point me out what am I doing wrong? I'm sending as an attachment the config.log generated file. Please let me know if you need any more information about my setup and environment.

A high level try at KVM for ARM

by Michael Hope

I've taken a stab at the medium term requirements for KVM on ARM: https://wiki.linaro.org/WorkingGroups/ToolChain/Specs/KVMEpic I haven't looked outside Linaro so apologies if this overlaps with other people's plans. Peter, this is high level and hopefully matches what's in your head. I want to use this to do a project plan, see if it can be done in 6-9 calendar months, and see if we need more people. Are there any implementation details that we should call out, similar to calling out virtio and UEFI? Rusty, this should tell you more about where we're going. Mounir, you, Peter, and I should turn this into a basic project plan. -- Michael

Hi, Does anyone have anything they'd like to bring up in tomorrow's performance call. ? I don't have any topics other than following on action items from last time's call - which was comparing movw/ movt with constant pools . https://wiki.linaro.org/WorkingGroups/ToolChain/Meetings/2012-01-10 Please add to it as you deem fit. cheers Ramana
