Gentleman, Again I'm porting a new version of android 4.3.1 to a piece of hardware I've already got older roms on. I've noticed that running reboot as super user at command line doesnt reboot most of the time, it just does emergency remounts and then hangs. I've run kernels/uboot from older bu

The clang -ftrapv option is not currently implemented efficiently for the type of integer computation-intensive code used in FLAC inner loops. The code generated for -ftrapv option doesn't yet take advantage of the ARM architecture's "V" (overflow) condition code bit. On Thursday, January 9, 201
