ABE - bug in copy_gcc_libs_to_sysroot() while building native toolchain for aarch64

by Virendra Kumar Pathak

Hi Linaro Toolchain Group, I am building a native toolchain for aarch64 with below configurations: --build=x86_64-unknown-linux-gnu --host=aarch64-linux-gnu --target=aarch64-linux-gnu. In copy_gcc_libs_to_sysroot() - which copy libgcc.a to sysroot, current implementation try to find the absolute path of libgcc.a as below : libgcc="`${local_builds}/destdir/${host}/bin/${target}-gcc -print-file-name=${libgcc}` But above line will not execute (i.e. gcc -print-file-name) on x86_64 as the toolchain is native toolchain for aarch64-linux-gnu. Thus a infinite loop will be created in copy command i.e. copying directory x in x. however, when I hard coded the libgcc.a path in my machine (as below), everything went fine. libgcc="/home/vpathak/arm/toolchain/build_abe_new/builds/destdir/aarch64-linux-gnu/lib/gcc/aarch64-linux-gnu/5.1.1/libgcc.a" I think this is a bug in ABE build infrastructure. Thanks. -- with regards, Virendra Kumar Pathak

* TCWG-806, aarch64 remote debugging multi-arch support. [4/10] Patches are done. Need to test them and polish them. Fix various multi-arch issues when --wrapper is used in GDBserver. Patches are pushed in to mainline. Could you describe this activity in more detail? Is the goal here to support mixed aarch32/aarch64 in the same GDB binary and detect the change at runtime? Thanks. -Duane
