IBM Z: Spectre: Prevent thunk cfi to be emitted with -fno-dwarf2-cfi-asm
The CFI magic we emit as part of the indirect branch thunks in order to
have somewhat sane unwind information must not be emitted with
-fno-dwarf2-cfi-asm.
gcc/ChangeLog:
2018-04-12 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/s390.c (s390_output_indirect_thunk_function): Check
also for flag_dwarf2_cfi_asm.
gcc/testsuite/ChangeLog:
2018-04-12 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
