 |-----------
 ||-Ofast          ||Disregard strict standards compliance. -Ofast enables all -O3 optimizations. It also enables optimizations that are not valid for all standard-compliant programs. It turns on -ffast-math and the Fortran-specific -fstack-arrays, unless -fmax-stack-var-size is specified, and -fno-protect-parens.  ||
+||-g           ||Produce debugging information in the operating system's native format. ||
+||-ffpe-trap=  ||Specifies a list of IEEE exceptions when a Floating Point Execption (FPE) should be raised. ''invalid'': invalid floating point operation, such as SQRT(-1.0), ''zero'': division by zero, ''overflow'': overflow in a floating point operation. ||
+||-fbacktrace  ||Specify that, when a runtime error is encountered or a deadly signal is emitted (segmentation fault, illegal instruction, bus error or floating-point exception), the Fortran runtime library should output a backtrace of the error.  ||
