From 066e28ccecb4bad5c0477606a138591f1da1963e Mon Sep 17 00:00:00 2001 From: Raffi Enficiaud Date: Mon, 30 Jan 2017 22:09:12 +0100 Subject: [PATCH] Preventing the compilation of floating points with GCC when glibc is not in use - Gathering the support of FPE in one place/several macros and using those in both execution_monitor.hpp and execution_monitor.ipp in a more coherent way - Updating the support of the floating point exceptions: fenableexcept/fdisableexcept are GLIBC extensions and the definition of FENV does not imply the existance of those functions Fetch from: https://github.com/boostorg/test/commit/066e28ccecb4bad5c0477606a138591f1da1963e [Adjust github patch to tarball release] Signed-off-by: Jörg Krause --- boost/test/execution_monitor.hpp | 17 +++++++++++++++-- boost/test/impl/execution_monitor.ipp | 21 +++++++-------------- 2 files changed, 22 insertions(+), 16 deletions(-) diff --git a/boost/test/execution_monitor.hpp b/boost/test/execution_monitor.hpp index f53348a..12c5644 100644 --- a/boost/test/execution_monitor.hpp +++ b/boost/test/execution_monitor.hpp @@ -66,6 +66,19 @@ #endif +#if defined(BOOST_SEH_BASED_SIGNAL_HANDLING) && !defined(UNDER_CE) + //!
