From 0ee4a543648a4c183a27b7d953317a99f6f30928 Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Wed, 2 May 2018 15:34:24 +0100 Subject: [PATCH] base: Add a M5_PUBLIC and M5_LOCAL attribute macro There are cases where we need to limit the symbol visibility to avoid compilation errors. This is a problem for Python code that relies on PyBind11 since recent versions enforce hidden symbols. As a consequence, classes that have member variables from PyBind11 need to be declared with the hidden attribute (or gem5 needs to be compiled with -fvisibility=hidden).
