Bug ID: 97359
Summary: ice in logical_combine, at gimple-range-gori.cc:754
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
The attached C code, when compiled by recent gcc trunk
and compiler flag -O2, does this:
$ ../results/bin/gcc -c -O2 -w bug651.c
during GIMPLE pass: evrp
bug651.c: In function ‘func_14’:
bug651.c:12278:1: internal compiler error: in logical_combine, at
gimple-range-gori.cc:754

I'll have a go at reducing the code.
