Max Filippov 130ea8322b target/xtensa: linux-user: add call0 ABI support ... Xtensa binaries built for call0 ABI don't rotate register window on function calls and returns. Invocation of signal handlers from the kernel is therefore different in windowed and call0 ABIs. There's currently no way to determine xtensa ELF binary ABI from the binary itself. Add handler for the -xtensa-abi-call0 command line parameter/QEMU_XTENSA_ABI_CALL0 envitonment variable to the qemu-user and record ABI choice. Use it to initialize PS.WOE in xtensa_cpu_reset. Check PS.WOE in setup_rt_frame to determine how a signal should be delivered.
