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
|
|
