When running the selftests, I run into: ... $ gdb -q -batch -ex "maint selftest" ... Running selftest execute_cfa_program::aarch64:ilp32. warning: A handler for the OS ABI "GNU/Linux" is not built into this configuration of GDB. Attempting to continue with the default aarch64:ilp32 settings. ... and likewise for execute_cfa_program::i8086 and execute_cfa_program::ia64-elf32. The warning can easily be reproduced outside the selftests by doing: ... $ gdb -q -batch -ex "set arch aarch64:ilp32" ... and can be prevented by first doing "set osabi none". Fix the warning by setting osabi to none while doing selftests that iterate over all architectures. Tested on x86_64-linux.
