Bug ID: 86831
Summary: three failures in gfortran.fortran-torture with
"-Ofast -march=native" on skylake-avx512
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: janus at gcc dot gnu.org
Target Milestone: ---
Triggered by two recent avx512 bugs with Fortran code (PR 86735 and PR 86828),
I just tried the following:

Running "make check-fortran" with this mod on a skylake-avx512 CPU yields the
following failures:
