Hi,
* rewrote the Android.mk of libunwind to make use of autoreconf and libtool * finished my work on libunwind * upgraded my Linaro Android build environment * debugged Linaro Android build failures (#891753) * tested backtracing on the Linaro Android 2.3.5 and 2.3.7 branches * documented debuggerd usage on Android: https://wiki.linaro.org/Platform/Android/DebugAndroidSystemComponents * Debugged a linking failure of the android perflab benchmark that Andy is seeing. Turns out that the GCC is optimizing two consecutive calls to sinf and cosf (same angle) are optimized by the GCC to one sincosf call. The libm provided by the benchmark is lacking sincosf. Workaround is to use -fno-builtin-sinf -fno-builtin-cosf.
Regards Ken
