Bug ID: 118458
Summary: No mechanism to disable all warnings locally
(supported by Clang with diagnostic ignored
"-Weverything")
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: stephenberry.developer at gmail dot com
Target Milestone: ---
With Clang it is possible to locally disable all warnings where they may be
invalid or unhelpful:
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Weverything"
// ... Code here for which we want to disable warnings
#pragma clang diagnostic pop
It is extremely helpful to be able to enable -Wall and -Werror on codebases, to
ensure all warnings are handled by developers. However, there are some corner
cases where the compiler may issue a warning that the developer cannot fix or
for which there is no issue and the code is 100% standard compliant.
I develop the C++ Glaze library and this issue prevents users from enabling
-Werror, because I have no means of disabling some warnings with GCC.
On Clang, myself and other developers can use -Werror, because it is possible
to disable warnings where they are rightly ignored.
It would be wonderful for GCC to add support for: diagnostic ignored
"-Weverything"
Thanks for your consideration,
Stephen
