== Issues == * None. == Progress == * Update "Keep constants in register when expanding" patch according to comments (TCWG-486, 3/10). * Refine ccmp patches since the old ones can not apply (TCWG-488, 2/10). * Check PR62151, it was exposed by my commit r211885. But the root cause was r208165. * R/M toolchain related work (5/10) == Plans == * Ping pending patches. == Planed leaves == * Aug. 18 - 26.

configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES

by Črt Gorup

Hi, I am trying to build a working environment with Angstrom Linux, QT5 for Toradex Apalis iMX6 module and additional QT5 SDK for my host machine. The compilation of Angstrom with additional QT5 layer went fine. However, there are some problems when building toolchain for the host machine (command meta-toolchain-qt5). It seems that there is a problem with configuration of linaro gcc runtime 4.8. The reported error is: "checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES". The log file is in the attachment. Does anyone have any idea how to fix this problem? I am using Ubuntu 14.04. Thanks in advance, Crt Gorup

Linaro arm-linux-gnueabihf-gdb versus Ubuntu gdb-multiarch

by ssinfod ssinfod

Hello, I'm trying to perform cross platform remote debugging from my x86 computer to a remote ARM device. (ex: Beagle Bone Black) I'm using Ubuntu 14.04 and Eclipse CDT. I installed the Ubuntu package gcc-arm-linux-gnueabihf but the gdb debugger is not in that package. Therefore, I'm wondering if I should use the Linaro toolchain (which include arm-linux-gnueabihf-gdb) or if I should install the Ubuntu gdb-multiarch package. What is the difference between gdb-multiarch and arm-linux-gnueabihf-gdb ? Is it better to use gdb-multiarch ? Thanks ssinfod

== Progress == * Fixed aarch64_be-none-elf builds and cross tests. (2/10) * Forked ancient RSH support in DejaGnu to be more SSH aware. SSH is now takes 1/4 of the time it used to for each remote execution test case. (TCWG 512 - 4/10) * Stabilized new ZSSH protocol in DejaGnu, also much faster than the current RSH/SSH support. (TCWG 512 - 3/10) * Meetings and Misc. (1/10) == Plan == * Get my D01 board working finally, since I killed my Odroid U2. * Review benchmarking patches. * Do more thorough testing of SSH performance improvements.

== Progress == * TCWG-180 Debugging - LTO bootstrap failure in Aarch64 with GCC 4.9. (6/10) Tried to recompile object files that showed differences in GCC trunk on amd64 machine.It turned out that GCC make system always builds LTO files in “gcc” directory and uses prev-gcc/xg++ to build them. No differences when building stage2 and stage3 objects under same directory “gcc” in FSF trunk. Doing the same experiment with gcc 4.9 branch shows failure both in x86_64 and aarch64. Communicated the issue to Richard Beiner. Got some feedback on debugging from Honza and Richard. Tried passing –save-temps to BOOT_CFLAGS using FSF trunk, getting assembler errors. Need to come back to this problem after finding root cause. Read about LTO passes and wpa (partitioned ) vs non portioned mode. * Others (2/10) * Upstream patch review. * 1-1 Meeting Christophe. * Misc and internal meeting. * setup LLVM. * Friday off (2/10). == Plan == * Continue LTO bootstrap issue. * Benchmark Core mark with LTO. * Upstream patch review. == MISC == * National holiday on 15th August .
