Hello, below patches add support for big-endian aarch64 to linux-user. Almost everything is already in place. The patches just set up the CPU flags as required for big-endianess, add a distinction in uname and make sure the instructions for the signal trampoline end up in memory little-endian. Finally, configure is extended to allow building of a aarch64_be-linux-user target and scripts/qemu-binfmt-conf.sh to include the binfmt magic for aarch64_be ELF files.
With this I am able to run individual aarch64_be binaries as well as chroot into a full-blown aarch64_be userland using binfmt_misc, running and compiling things (Gentoo crossdev/native). v2: - add binfmt magic to qemu-binfmt-conf.sh - fix style problems (tab indenting) Thanks, Michael Michael Weiser (5): linux-user: Add support for big-endian aarch64 linux-user: Add separate aarch64_be uname linux-user: Fix endianess of aarch64 signal trampoline configure: Add aarch64_be-linux-user target linux-user: Add aarch64_be magic numbers to qemu-binfmt-conf.sh configure | 9 +++++---- default-configs/aarch64_be-linux-user.mak | 1 + linux-user/aarch64/target_syscall.h | 4 ++++ linux-user/main.c | 6 ++++++ linux-user/signal.c | 10 +++++++--- scripts/qemu-binfmt-conf.sh | 6 +++++- 6 files changed, 28 insertions(+), 8 deletions(-) create mode 100644 default-configs/aarch64_be-linux-user.mak -- 2.15.1
