This tests whether $ymm15 can be correctly collected and printed from tfile. It covers: - storing tdesc in tfile (without that, $ymm15 doesn't exist) - ax_pseudo_register_collect for x86 (without that, $ymm15 cannot be collected) - register order in tfile_fetch_registers (without that, $ymm15h is fetched from wrong position) - off-by-one in tfile_fetch_registers (without that, $ymm15h is incorrectly considered to be out of bounds) - using proper tdesc in encoding tracepoint actions (without that, internal error happens due to $ymm15h being considered unavailable) gdb/testsuite/ChangeLog: * gdb.trace/tfile-avx.c: New test. * gdb.trace/tfile-avx.exp: New test.
