# =========================================================================== # https://www.gnu.org/software/autoconf-archive/ax_tls.html # =========================================================================== # # SYNOPSIS # # AX_TLS([action-if-found], [action-if-not-found]) # # DESCRIPTION # # Provides a test for the compiler support of thread local storage (TLS) # extensions. Defines TLS if it is found. Currently knows about C++11, # GCC/ICC, and MSVC. I think SunPro uses the same as GCC, and Borland # apparently supports either. # # LICENSE # # Copyright (c) 2008 Alan Woodland <ajw05@aber.ac.uk> # Copyright (c) 2010 Diego Elio Petteno` <flameeyes@gmail.com> # # This program is free software: you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by the # Free Software Foundation, either version 3 of the License, or (at your # option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
