If you look at upstream SVN GCC and do svn propget svn:ignore you get a long list of files that SVN is set up to ignore. And whilst there isn't a .gitignore other upstream projects which have git mirrors do put a .gitignore in place (see GDB for instance). I think having a .bzrignore which is a copy of the svn:ignore set up (and the defaults that SVN ignores but aren't on bzr's list) would be valid in the repo. Although as I said in the original thread - let's do this when we branch 4.8 and not to the historic branches.

by Zhenqiang Chen

The Linaro Toolchain Working Group is pleased to announce the 2012.12 release of the Linaro Toolchain Binaries, a pre-built version of Linaro GCC and Linaro GDB that runs on generic Linux or Windows and targets the glibc Linaro Evaluation Build. Uses include: * Cross compiling ARM applications from your laptop * Remote debugging * Build the Linux kernel for your board What's included: * Linaro GCC 4.7 2012.12 * Linaro GDB 7.5 2012.12 * A statically linked gdbserver * A system root * Manuals under share/doc/ The system root contains the basic header files and libraries to link your programs against. The Linux version is supported on Ubuntu 10.04.3 and 12.04, Debian 6.0.2, Fedora 16, openSUSE 12.1, Red Hat Enterprise Linux Workstation 5.7 and later, and should run on any Linux Standard Base 3.0 compatible distribution. Please see the README about running on x86_64 hosts. The Windows version is supported on Windows XP Pro SP3, Windows Vista Business SP2, and Windows 7 Pro SP1. The binaries and build scripts are available from: https://launchpad.net/linaro-toolchain-binaries/trunk/2012.12 Need help? Ask a question on https://ask.linaro.org/ Already on Launchpad?

== Progress == * Release week: - Made 2012.12 release of gcc-linaro 4.6 and 4.7. - took lot of time (infrastructure, right acess, Lava lab migration) * GCC atomic builtins: - my load acquire patch was applied up-stream (trunk and 4.7). - some cleaning in optabs.c (patch applied up-stream too). == Next == * Resume Boehm GC AArch64 support. * Review roster.

== Progress == * gdb-linaro-7.5-2012.12 release - Updated wikis about gdb sources import from upstream and about gdb-linaro release - still some trouble with infrastructure to achieve the release * 64-bits ops in Neon: no news from upstream * disable-peeling: upstream advice is to enable & tune the vectorizer cost model first, but there seems to be an agreement that if unaligned accesses have no penalty, peeling should not be considered. Updated the vectorizer-cost-model blueprint * builtin_bswap16 backport to linaro-4.7: the i686 regression was caused by the build process. Re-spawned the jobs after fixing the remaining arm issue * cbuild: briefly looked at some scripts to better understand the whole system, while tracking a problem in the gdb validation reports == Next == * handle 64-bits bitops in Neon and disable-peeling feedback from upstream if any * finish builtin_bswap16 backport == Future == * on holidays for 2 weeks (Dec 22th-Jan 6th)

Clearing out past branches

by Michael Hope

Hi Ramana. You have the following branches remaining on Launchpad: * lp:~ramana/gcc-linaro/47-lower-subreg-experiments * lp:~ramana/gcc-linaro/47-improve-neon-intrinsics * lp:~ramana/gcc-linaro/47-nobble-promote-mode * lp:~ramana/gcc-linaro/47-smin-umin-idiom Which are obsolete, which should be spun out into backlog blueprints, and which should be taken over by someone? -- Michael

Summary: * Validate RM toolchain * Prepare Linaro Toolchain Binaries 2012.12 release. * Collect performance data for different branch cost. Details: 1. Validate RM toolchain release. 2. Collect denbench and spec2000int performance data for branch cost tuning. 3. Fix README issue (lp:1068402) by dynamically create README.txt: * The hard coded README.txt is removed. * Update build scripts to generate the README.txt, which depends on - README.texi, which is the common template for all TARGETS. - config.texi, which sets the default configuration for the TARGET. Each TARGET has a config.texi. - version.texi, created during build, includes GCC_VERSION, GDB_VERSION and TOOLCHAIN_VERSION. 4. Update Linaro GCC and GDB to 2012.12 in Linaro crosstool-ng, workaround gdb mingw32 link fail issue (due to mbsrtowcs is redefined in gdb/gnulib), finish the smoke test and spawn release builds. Plans: * Investigate how branch cost impacts on code generation. * Release Linaro Toolchain Binaries 2012.12. Best regards! -Zhenqiang

[ANNOUNCE] Linaro GDB 7.5 2012.12 released

by Christophe Lyon

The Linaro Toolchain Working Group is pleased to announce the release of Linaro GDB 7.5.
