Hi, gcc 4.8 has been released a couple of days ago - so I'm getting our tree in shape to work with it.
I've created a toolchain tarball that works the same as our usual toolchain releases here: https://android-build.linaro.org/builds/~linaro-android/toolchain-fsf-4.8.0/
I've also gone through the repository and fixed all build issues (also submitted the related patches to AOSP).
Unfortunately, this time Microsoft QA ("It compiles, therefore it works(TM)") failed to detect the issues -- looks like the build works, but creates some binary incompatibilities with blobs (e.g. undefined references to __aeabi_uidiv in Galaxy Nexus graphics drivers), so there's some work left to do -- but for those who are ready to experiment (or don't need *****ing blobs), it's ready to go.
