From 9d54400bba7eb04bca80fce97fa170452d19eaf1 Mon Sep 17 00:00:00 2001 From: Serge Guelton Date: Tue, 11 Apr 2017 15:01:18 +0000 Subject: [PATCH] Module::getOrInsertFunction is using C-style vararg instead of variadic templates. From a user prospective, it forces the use of an annoying nullptr to mark the end of the vararg, and there's not type checking on the arguments. The variadic template is an obvious solution to both issues.
