            Bug ID: 107485
           Summary: gcc-10 ICE with -fnon-call-exception
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: spop at gcc dot gnu.org
  Target Milestone: ---

On arm64-linux I see the following crash only on gcc-10.
I do not see the ICE on gcc-11, 12, and trunk.

commit 1e676cfbe1e13fba2c636b560362ed4f0a56893d
Author: Richard Biener <rguenther@suse.de>

    middle-end/95171 - inlining of trapping compare into non-call EH fn

    This fixes always-inlining across -fnon-call-exception boundaries
    for conditions which we do not allow to throw.

    2020-05-18  Richard Biener  <rguenther@suse.de>

            PR middle-end/95171
            * tree-inline.c (remap_gimple_stmt): Split out trapping compares
            when inlining into a non-call EH function.

            * gcc.dg/pr95171.c: New testcase.
