== Progress == * Zero/sign extension elimination with widening types (1/10) - Addressing comments from the review * BUG #398 #412 (5/10) - built kernel revision with provided config and toolchain binary release to reproduce gcc segafult. Couldn’t reproduce it. Since there is no more details to reproduce, closed it as cant reproduce. - Spec2k gcc optimization issue was reproduced and reduced test-case was created. - dumps shows that this issue could be related to splitting constants for early during expand might be the root cause. * Holiday (4/10) == Plan == * Continue with Zero/sign extension. * BUG #412 == Planned Leave == * 11/12/2014 to 24/12/2014 - 10 days

ABE benchmarking - TCWG-360 [4/10] * Implemented most of a solution to the 'must be in same network' restriction libm exercising - TCWG-558 [4/10] * lulesh generates needless calls to pow on AArch64 (as opposed to 'pow is slow') ** Working on a reduced test case * Ran a chunk of benchfft, left a process searching the perf reports for libm calls * More chroot/glibc fiddling * Decided Graph500 was unlikely to be interesting Misc - [2/10] =Plan= On holiday Monday - Wednesday More lulesh, benchfft results Think about where to go next with libm exercising Complete 'same network' workaround, test benchmark repeatability Port benchmarking scripts to ABE repo Get storage/automation started, if Rob has time

building eglibc for arm-linux-gnueabihf tools with multilib support

by Mallikarjun.Gouda＠freescale.com

Hi All, Currently linaro toolchain for arm-linux-gnueabihf built with crosstool-ng scripts uses prebuilt sysroot. I am trying to build eglibc on my own without using prebuilt sysroot. I am not able to exactly create same layout in the library layout. Linaro build layout looks: gcc-linaro-arm-linux-gnueabihf-4.8-2014.01_linux\arm-linux-gnueabihf\libc\usr\lib --> arm-linux-gnueabi arm-linux-gnueabihf one for soft float and other for hard float fp. Can anybody please tell how we tell build system to create directories like above while building eglibc? I used following commands to build eglibc: ../src_eglibc/configure --disable-profile --without-gd --without-cvs --prefix=/usr libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes --with-headers=<some_dir>/arm-linux-gnueabihf/libc/usr/include --host=arm-linux-gnueabihf Make all make install install_root= <some_dir>/arm-linux-gnueabihf/libc/ Thank you very much for your help. //Mallikarjuna
