Just realized I forgot to send the report last week, so I'm combining them. == Progress == * Got AOSP to build with clang for all Nexus devices * Submitted all related patches upstream, most are accepted, 34 remaining in the queue * Wrote a script that pulls related patches directly from AOSP's gerrit * Looked at boot failure with clang-built init; no final results yet (clang-built init does start up properly, but reboots at some point that needs to be identified) * Looked at UI startup failure with clang-built AOSP; no final results yet (building the most suspected components such as surfaceflinger, opengl, hwui, ... with gcc doesn't help) * Started preparing for my Linux Plumbers Conf talks * Looked at installjammer and NSIS to replace the Windoze installer for toolchain binaries (cbuild1 built this automatically, cbuild2 currently doesn't). Picked NSIS. == Plans == * Finish preparations for my Linux Plumbers Conf talks * Attend Linux Plumbers Conf * Toolchain releases == Issues == * none
