Hi,
I just realised: Since C++17, noexcept is part of the mangled name. That
means that adding noexcept to an exported function is BiC now! Please be
aware of this when reviewing patches.
Since non-template inline members of exported classes are exported, too,
in MSVC Debug builds, the same is true for them: You can no longer add
noexcept to inline functions of exported classes (yet another reason to
avoid exporting non-polymorphic classes wholesale; individually export
single functions instead).
Do we need a new macro (Q_DECL_CPP17_COMPATIBLE_NOTHROW?) that expands
to nothing on MSVC Debug builds?
Or should we simply dodge the issue and declare debug builds of Qt not
subject to BC on MSVC?
Thanks,
Marc
