/* What are the C types corresponding to the real(kind=10) and
|
|
real(kind=16) types? We currently rely on the following assumptions:
|
|
-- if real(kind=10) exists, i.e. if HAVE_GFC_REAL_10 is defined,
|
|
then it is necessarily the "long double" type
|
|
-- if real(kind=16) exists, then:
|
|
* if HAVE_GFC_REAL_10, real(kind=16) is "__float128"
|
|
* otherwise, real(kind=16) is "long double"
|
|
To allow to change this in the future, we create the
|
|
GFC_REAL_16_IS_FLOAT128 macro that is used throughout libgfortran. */
