These options affect the runtime behavior of programs compiled with GNU Fortran.
-fconvert=
conversionOn POWER systems which suppport -mabi=ieeelongdouble, there are additional options, which can be combined with others with commas. Those are
REAL(KIND=16)
.
REAL(KIND=16)
.
This 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.
-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.
