Bug ID: 71559
Summary: ICE in ix86_fp_cmp_code_to_pcmp_immediate, at
config/i386/i386.c:23042 (KNL/AVX512)
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: tripiana at gmail dot com
Target Milestone: ---
Created attachment 38714

intermediate (assembly) file
When compiling scipy code with GFORTRAN in a KNL/AVX512 (does not happens in
other machines with the same stack). The --save-temps only generates a *.s file
(attached):
