Make anti_adjust_stack_and_probe_stack_clash extern and use it for Z
When compiling with -mbackchain -fstack-clash-protection currently no
probes are emitted. This patch adjusts the "allocate_stack" expander
to call anti_adjust_stack_and_probe_stack_clash when needed. In order
to do this I had to export that function from explow.c.
Ok for mainline?
gcc/ChangeLog:
2020-05-14 Andreas Krebbel <krebbel@linux.ibm.com>
* config/s390/s390.md ("allocate_stack"): Call
anti_adjust_stack_and_probe_stack_clash when stack clash
protection is enabled.
* explow.c (anti_adjust_stack_and_probe_stack_clash): Remove
prototype. Remove static.
* explow.h (anti_adjust_stack_and_probe_stack_clash): Add
prototype.
gcc/testsuite/ChangeLog:

* gcc.target/s390/stack-clash-3.c: New test.
