From e0ed9025cf7453212e5e5a845e34e0b7ecfa3eb9 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Fri, 7 Oct 2016 12:58:17 +0200 Subject: Add option to use Ada code in ramstage If selected, libgnat will be linked into ramstage. And, to support Ada package intializations, we have to call ramstage_adainit().
