Bug ID: 126203
Summary: [17 Regression] ICE in maybe_legitimize_operand, at
optabs.cc:8427 since r17-1764
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: mjires at gcc dot gnu.org
CC: lin1.hu at intel dot com
Target Milestone: ---
Target: x86_64-pc-linux-gnu
Compiling reduced testcase gfortran.dg/do_concurrent_2.f90 results in ICE since
r17-1764-gc2cdc43bc60b32.
$ cat do_concurrent_2.f90
integer A(5,5)
if (any (A(:,5) /= [9, 9, 9, 9, 5])) STOP
end
$ gfortran do_concurrent_2.f90 --param=vect-partial-vector-usage=2 -mavx10.1
-O3
during RTL pass: expand
