Bug ID: 97265
Summary: new warning with clang build
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
I just tried a build of gcc trunk with clang. It said
trunk.git/gcc/vec.h:543:13: warning: 'constexpr' non-static member function
will not be implicitly 'const' in C++14; add 'const' to avoid a change in
behavior [-Wconstexpr-not-const]
I don't remember this warning from last week's clang build.
Source code is
CONSTEXPR operator vec<T, A, L> () { return vec<T, A, L>(); }
My best guess is that
CONSTEXPR operator vec<T, A, L> () const { return vec<T, A, L>(); }
will shut up clang.

It also makes the function more consistent whether CONSTEXPR expands to constexpr or not. ^ permalink raw reply [flat|nested] 3+ messages in thread
