Doc Type: Enhancement
Doc Text:
.Vectorized math library is now enabled for GNU Fortran in GCC Toolset 9 With this enhancement, GNU Fortran from GCC Toolset can now use routines from the vectorized math library `libmvec`. Previously, the Fortran compiler in GCC Toolset needed a Fortran header file before it could use routines from `libmvec` provided by the GNU C Library `glibc`.

Description Florian Weimer 2019-10-22 14:04:39 UTC
We should backport these enhancements:

commit dc0afac3252d0c53716ccaf0b424f7769a66d695
Author: marxin <mliska@suse.cz>
Date:   Wed Feb 20 14:54:35 2019 +0100

    Add new Fortran vector math header file.

commit ae514971341dcc08ec7f8622493a65e7eb1ef9d2
Author: marxin <mliska@suse.cz>
Date:   Thu Mar 7 09:39:55 2019 +0100

    Fix location where math-vector-fortran.h is installed.

commit 27a2f2f34c9e77815c6367cf670e24cbac0db7c0
Author: Florian Weimer <fweimer@redhat.com>
Date:   Thu Mar 7 17:28:13 2019 +0100

    check-wrapper-headers test: Adjust Fortran include file directory

These also need to be backported into Fedora 30+.

Comment 1 Florian Weimer 2019-11-06 10:17:06 UTC
I'm dropping the check-wrapper-headers changes from the backport because that is not a test we have downstream. I did backport it, but we lack various header cleanups, and the test fails as a result.

Comment 5 Sergey Kolosov 2020-03-12 12:39:11 UTC
Verified, glibc-2.28-89.el8 contains these files.
