Bug ID: 93506
Summary: Create hybrid of -I and -isystem that is like -I but
deactivates warnings
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: fiesh at zefix dot tv
Target Milestone: ---
Being guilty of abusing -isystem a lot to silence warnings in third-party
libraries, it would be great if there were a spin off of -I that ignored
warnings just like -isystem does but otherwise behaves like -I.
(An argument that is brought up sometimes, namely that third-party libraries
should fix their warnings, isn't really valid I believe.
For example, constexpr variables became implicitly inline in C++17. Before
that, one had to define them in translation units. So libraries remaining
pre-C++17 compatible will want to do that, while projects that compile in C++17
might prefer warnings about deprecated things being done.
Also, from a practicality point of view, it is simply not a meaningful
argument.)
