Reconfig libc's Android.mk to build for multilib 1. Moved arch-specific setup to their own files: - <arch>/<arch>.mk, arch-specific configs. Variables in those config end with the arch name. - removed the extra complexity introduced by function libc-add-cpu-variant-src, which seems to be not very useful these days. 2. Separated out the crt object files generation rules and set up the rules for both TARGET_ARCH and TARGET_2ND_ARCH. 3. Build all the libraries for both TARGET_ARCH and TARGET_2ND_ARCH, with the arch-specific LOCAL_ variables. Bug: 11654773 Change-Id: I9c2d85db0affa49199d182236d2210060a321421

Add 32-bit Silvermont-optimized string/memory functions. Add following functions: bcopy, memcpy, memmove, memset, bzero, memcmp, wmemcmp, strlen, strcpy, strncpy, stpcpy, stpncpy. Create new directories inside arch-x86 to specify architecture: atom, silvermont and generic (non atom or silvermont architectures are treated like generic). Due to introducing optimized versions of stpcpy and stpncpy, c-implementations of these functions are moved from common for architectures makefile to arm and mips specific makefiles.

Add ARMv8 optimized string handling functions based on cortex-strings This adds ARMv8 optimized string handling functions to Bionic. The implementations live in a generic/ directory because there will likely be more CPU specific versions (e.g. Cortex-A53 vs. Cortex-A57) later. These implementations are 50%+ faster on current v8 models. Change-Id: If3adc54a284d9519459b0d4d4390f0cd6ded8786 Signed-off-by: Bernhard Rosenkraenzer <Bernhard.Rosenkranzer@linaro.org>
