From 3f14b27dec6f4a590d8ae0ffcbb7cf7714815a05 Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Fri, 3 May 2019 10:55:25 -0700 Subject: Port manywarnings to GCC 9 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * build-aux/gcc-warning.spec: Sort. Add -Wattribute-alias, -Wc11-c2x-compat, -Wcast-result (for the D programming language), -Wclass-conversion, -Wdeprecated-copy, -Wdeprecated-copy-dtor, -Winit-list-lifetime, -Wpessimizing-move, -Wprio-ctor-dtor, -Wredundant-move. Adjust to minor wording changes in GCC 9’s --help=warnings output. * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Wabsolute-value, -Waddress-of-packed-member, -Wattribute-warning, -Wcannot-profile, -Wmissing-profile. Change -Wattribute-alias to -Wattribute-alias=2. --- build-aux/gcc-warning.spec | 32 +++++++++++++++++++++++--------- 1 file changed, 23 insertions(+), 9 deletions(-) (limited to 'build-aux/gcc-warning.spec') diff --git a/build-aux/gcc-warning.spec b/build-aux/gcc-warning.spec index 8c0a3dc750..723d287afa 100644 --- a/build-aux/gcc-warning.spec +++ b/build-aux/gcc-warning.spec @@ -1,23 +1,25 @@ # options to filter out, and why --all-warnings alias for -Wall --extra-warnings alias for -Wextra +-Wabi this is now a no-op -Wabi-tag c++ -Wabi= c++ --Wabi this is now a no-op -Waggregate-return obsolescent -Waliasing fortran -Walign-commons fortran -Waligned-new=[none|global|all] c++ --Walloca we like alloca in small doses --Walloca-larger-than= FIXME: choose something sane?
