From: Wolfgang Bangerth Date: Mon, 7 Dec 2015 21:49:50 +0000 (-0600) Subject: Make instantiation of functions more uniform. X-Git-Tag: v8.4.0-rc2~168^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=000667af4cbc27515fd0b8cf747307c349fc480b;p=dealii.git Make instantiation of functions more uniform. Specifically, allow the script to also instantiate for parallel distributed and shared Triangulation classes. This also allows to significantly simplify the list of explicit instantiations for GridTools. --- diff --git a/cmake/config/template-arguments.in b/cmake/config/template-arguments.in index a28f358e92..15e46dc7b7 100644 --- a/cmake/config/template-arguments.in +++ b/cmake/config/template-arguments.in @@ -70,10 +70,18 @@ DOFHANDLER_TEMPLATES := { DoFHandler; hp::DoFHandler } TRIANGULATION_AND_DOFHANDLER_TEMPLATES := { Triangulation; + parallel::shared::Triangulation; + parallel::distributed::Triangulation; DoFHandler; hp::DoFHandler } +SEQUENTIAL_TRIANGULATION_AND_DOFHANDLERS := { Triangulation; + DoFHandler; + hp::DoFHandler } + TRIANGULATION_AND_DOFHANDLERS := { Triangulation; + parallel::shared::Triangulation; + parallel::distributed::Triangulation; DoFHandler; hp::DoFHandler } diff --git a/doc/news/changes.h b/doc/news/changes.h index adc6b2400b..fc61369fc3 100644 --- a/doc/news/changes.h +++ b/doc/news/changes.h @@ -482,7 +482,15 @@ inconvenience this causes.
