Bug ID: 82248
Summary: probe_stack can generate unpredictable STR on arm
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sch...@linux-m68k.org
Target Milestone: ---
Target: arm*-*-*
The probe_stack insn uses "str r0,%0" with hard-coded reference to r0, but this
is unpredictable if %0 happens to use pre-indexed or post-indexed addressing
mode with r0 as base.
