() from /lib/x86_64-linux-gnu/libc.so.6^M (gdb) FAIL: gdb.reverse/step-precsave.exp: run to end of main The instruction at this address is: 0x00007ffff7f49b40: 62 e2 7d 48 7a c6 vpbroadcastb %esi,%zmm16 This seems like an AVX512 instruction (given the use of zmm16). Match this byte value in order to produce a KFAIL.
