HDFFV-8653 replace non-standard sizeof in the fortran tests with c_sizeof (1) Removed the overloaded h5_sizeof functions for characters and integer arrays since Sun compilers don't allow them to be passed into a function that uses sizeof. (2) Requested min. precision for reals to avoid duplicate interfaces when the flag -r8 (or equiv.) is set. tested: *jam: intel, -i8 -r8 --enable-fortran2003 *jam: pgi, --enable-fortran2003 *emu: sun, --enable-fortran2003

! H5_SIZEOF
|
|
!
|
|
! NOTES
|
|
! The Sun/Oracle compiler has the following restrictions on the SIZEOF intrinsic function:
|
|
!
|
|
! "The SIZEOF intrinsic cannot be applied to arrays of an assumed size, characters of a
|
|
! length that is passed, or subroutine calls or names. SIZEOF returns default INTEGER*4 data.
|
|
! If compiling for a 64-bit environment, the compiler will issue a warning if the result overflows
|
|
! the INTEGER*4 data range. To use SIZEOF in a 64-bit environment with arrays larger
|
|
! than the INTEGER*4 limit (2 Gbytes), the SIZEOF function and
|
|
! the variables receiving the result must be declared INTEGER*8."
|
|
!
|
|
! Thus, we can not overload the H5_SIZEOF function to handle arrays (as used in tH5P_F03.f90), or
|
|
! characters that do not have a set length (as used in tH5P_F03.f90), sigh...
