Hi guys. Yip, let's start doing this properly. Can I suggest the same as the Ubuntu relationship and methods? Basically: * You find an issue * Log a bug on Launchpad against the component or, failing that, linaro-android * Figure out if it is a toolchain or package problem * Figure out if there is a work around such as changing the optimisation level If it is a toolchain issue: * Feel free to do a work around in the package * Add the right tags so you can revert the workaround in the future * Mark the bug as affecting gcc-linaro * Provide sufficient information to reproduce the bug - preprocessed source would be great! and we'll get on to it. We'll need some help in setting up a test environment. Note that a lot of the triage work is on the distribution side (i.e. Android). -- Michael _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
