[-- Attachment #1: Type: text/plain, Size: 227 bytes --]

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

Tested powerpc64le-linux. Committed to trunk.

    libstdc++: Remove redundant -std=gnu++17 options from PSTL tests
    
    GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
    dg-options directive prevents running these tests with different modes
    such as -std=c++17 or -std=gnu++20.

[-- Attachment #1: Type: text/plain, Size: 228 bytes --]

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

Tested powerpc64le-linux. Committed to trunk.

[-- Attachment #1: Type: text/plain, Size: 227 bytes --]

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

Tested powerpc64le-linux. Committed to trunk.

[-- Attachment #1: Type: text/plain, Size: 228 bytes --]

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

Tested powerpc64le-linux. Committed to trunk.

[-- Attachment #1: Type: text/plain, Size: 227 bytes --]

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

Tested powerpc64le-linux. Committed to trunk.

    libstdc++: Remove redundant -std=gnu++17 option from PMR tests
    
    GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the

[-- Attachment #1: Type: text/plain, Size: 227 bytes --]

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

Tested powerpc64le-linux. Committed to trunk.

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

Tested powerpc64le-linux. Committed to trunk.

    libstdc++: Remove redundant -std=gnu++17 option from algorithm tests
    
    GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
    dg-options directive prevents running these tests with different modes
    such as -std=c++17 or -std=gnu++20.

[-- Attachment #1: Type: text/plain, Size: 227 bytes --]

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

Tested powerpc64le-linux. Committed to trunk.

commit 7c85abec763095045ba3f78c6656117dd8f1fd01
Author: Jonathan Wakely <jwakely@redhat.com>
Date:   Mon May 10 16:22:53 2021

    libstdc++: Remove redundant -std=gnu++17 option from containers tests
    
    GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
    dg-options directive prevents running these tests with different modes
    such as -std=c++17 or -std=gnu++20.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/23_containers/array/cons/deduction.cc: Remove
            -std=gnu++17 from dg-options directive.
