[gdb/testsuite] Add KFAIL for missing support of reverse-debugging xsave
Normally the gdb.reverse/*.exp test-cases pass on my system (apart from the record/23188 KFAIL for gdb.reverse/step-precsave.exp). But when specifying GLIBC_TUNABLES=glibc.tune.hwcaps=-XSAVEC_Usable to force glibc to use _dl_runtime_resolve_xsave instead of _dl_runtime_resolve_xsavec, we run into 1054 FAILs like this: ... (gdb) PASS: gdb.reverse/sigall-reverse.exp: b gen_HUP continue^M Continuing.^M Process record does not support instruction 0xfae64 at address \ 0x7ffff7ded958.^M Process record: failed to record execution log.^M ^M Program stopped.^M 0x00007ffff7ded958 in _dl_runtime_resolve_xsave () from \ /lib64/ld-linux-x86-64.so.2^M (gdb) FAIL: gdb.reverse/sigall-reverse.exp: get signal ABRT ... The problem is that the xsave instruction is not supported in reverse-debugging (PR record/25038). Add KFAILs for this PR. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-10-13 Tom de Vries <tdevries@suse.de> PR record/25038 * gdb.reverse/sigall-precsave.exp: Add PR record/25038 KFAIL. * gdb.reverse/sigall-reverse.exp: Same. * gdb.reverse/solib-precsave.exp: Same. * gdb.reverse/solib-reverse.exp: Same. * gdb.reverse/step-precsave.exp: Same. * gdb.reverse/until-precsave.exp: Same. * gdb.reverse/until-reverse.exp: Same. * lib/gdb.exp (gdb_continue_to_breakpoint): Same.
