Subject: Mark a DEAL_II_CONSTEXPR function as inline.
X-Git-Tag: v9.3.0-rc1~495^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F11695%2Fhead;p=dealii.git

Mark a DEAL_II_CONSTEXPR function as inline.

This is necessary for those cases where DEAL_II_CONSTEXPR expands to nothing
because of a compiler bug. In all other cases, the 'inline' is redundant because
'constexpr' functions are automatically 'inline'.
