Next: Code Gen Options, Previous: Link Options, Up: Invoking GNU Fortran
These options affect the runtime behavior of programs compiled with GNU Fortran.
-fconvert=
conversionThis option has an effect only when used in the main program.
The CONVERT
specifier and the GFORTRAN_CONVERT_UNIT environment
variable override the default specified by -fconvert.
-fno-range-check
READ
operations.
For example, GNU Fortran will give an error if an input value is
outside of the relevant range of [-HUGE()
:HUGE()
]. In other words,
with INTEGER (kind=4) :: i
, attempting to read -2147483648 will
give an error unless -fno-range-check is given.
-frecord-marker=
length-fmax-subrecord-length=
length-fsign-zero
SIGN
intrinsic. -fno-sign-zero does not
print the negative sign of zero values (or values rounded to zero for I/O)
and regards zero as positive number in the SIGN
intrinsic for
compatibility with Fortran 77. The default is -fsign-zero.
