IBM Z: stack clash prot: add missing updates of last_probe_offset
After emitting probes in a loop last_probe_offset needs to be updated.
Not doing this usually assumes a too low distance to the last access
when emitting the remainder leading to stack probes being omitted.
gcc/ChangeLog:
2020-05-14 Andreas Krebbel <krebbel@linux.ibm.com>
* config/s390/s390.c (allocate_stack_space): Add missing updates
of last_probe_offset.
gcc/testsuite/ChangeLog:
