== Progress == * Meetings and Misc (3/10) - Upgraded my Samsung Chromebook to boot Ubuntu trusty instead of using crouton. Works much better for native builds now. * Worked on perfecting building binary tarballs in a 32bit chroot that run on any platform. (TCWG 383 - 7/10) - Added zlib to infrastructure so libz.so.1 can be found at runtime. - Force libgloss to build for bare metal. - Fixed minor issues with Canadian cross builds. == Plan == * Figure out why Canadian cross builds fail on the TCWG build farm, but work on my local machines. * Continue improving building binary releases. * Get D01 board setup and working. * Get back to test result verification automation. - rob -

by Christophe Lyon

Short week (2 days off) (4/10) == Progress == * GCC trunk cross-validation (CARD-647) (2/10) - reported 2 new compiler build failures and 2 regressions - tested one proposed patch, which did not fix the regression - trunk now builds OK again * Neon intrinsics tests (1/10) - cleaned branch to prepare submission - working on Cumulative Saturation Neon flag support for AArch64 * aarch64 libsanitizer support - resumed work: libsanitizer no longer builds with recent glibc, will need to patch it upstream before bringing it back to GCC. - testing will be difficult using qemu since libsanitizer reserves a huge chunk of memory at startup (8GB) which may not be available on the host machine * Misc (meetings, conf-calls, ....) (3/10) - 1:1 calls, weekly calls - backports review == Next == * GCC trunk cross-validation: - test Kugan's patch before submission - evaluate effort to develop a mail-driven support for testing patches vs trunk befiore submission - add support for validation of FSF-4.9 branch * Neon intrinsics tests - add support for Cumulative Saturation Neon flags on AArch64 * AArch64 libsanitizer - discuss how to make cross-testing more practical

== Progress == * Zero/sign extension elimination (TCWG-15) (7/10) - regression tested and fixed all the issues - final bootstrap and regression testing for arm and x86_64 are ongoing - will post the patch for comment after checking the results * benchmarking (TCWG-468) (1/10) - Set-up chrome-book for a15 release benchmarking * SAH1 performance (TCWG-413) (2/10) - Christophe noted regression for aarch64_be due to clean-up patch. - register_move_cost hook in aarch64 does not handle all the cases (CORE_REGS and POINTER_REGS) and due to this, it calculates FP2FP cost for these classes . With CORE_REGS gone, costs for register classes are now different. Cost table needs adjustment. * FENV for C11 TCWG-447 - Committed ARM part. == Plan == * Benchmarking. * Upstream zero/sign extension elimination activities. * sha1 performance.

Prebuilt Linaro 2014.04 arm-linux-gnueabihf: cannot find /lib/ld-linux-armhf.so.3

by Denys Dmytriyenko

Hi, I've been having this issue with latest binary Linaro 2014.04 toolchain from http://releases.linaro.org/14.04/components/toolchain/binaries/gcc-linaro-a… It comes with own sysroot, but linker fails to locate /lib/ld-linux-armhf.so.3 $ make arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o nvs.o nvs.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o misc_cmds.o misc_cmds.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o calibrator.o calibrator.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o plt.o plt.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o wl18xx_plt.o wl18xx_plt.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o ini.o ini.c arm-linux-gnueabihf-gcc -L/tmp/lib/ nvs.o misc_cmds.o calibrator.o plt.o wl18xx_plt.o ini.o -lm -lnl-3 -lnl-genl-3 -o calibrator /opt/linaro-2014.04/bin/../lib/gcc/arm-linux-gnueabihf/4.8.3/../../../../arm-linux-gnueabihf/bin/ld: cannot find /lib/ld-linux-armhf.so.3 collect2: error: ld returned 1 exit status Makefile:26: recipe for target 'all' failed make: *** [all] Error 1 And when I pass my own sysroot, it works fine. Is it supposed to work as a standalone toolchain with its own bundled sysroot? Thanks. -- Denys
