XL Fortran Bogus Error on Assumed Shape Dummy Argument of BIND(C) Procedure

The XL Fortran compiler gives a bogus error message for the below valid Fortran program. The restriction that presumably generates this error message was replaced in Fortran 2018 standard (sec 18.3.6 point 5). Furthermore, the XL compiler provides...

Provide Fortran compiler option to force variables to be explicitly declared

The IMPLICIT none statement is available to us, but it has to be coded in every single program, subroutine and function, whereas a compiler option would not require a code modification to enforce explicit declarations. The PL/I compiler has the RU...

XLF: Compiler should detect and isolate the source of non-conforming Openmp code using local pointers for data maps.

SalesForce Case: TS001878905PMR: 80808,227,000 The use case reproducer for this issue is an OpenMP Fortran implementation that uses local, temporary pointers to do data mapping. The implementation does not conform to the OpenMP spec but the compil...

XLF: Support for Fortran 2008 feature move_alloc

The feature is described in section "5.3 Allocatable components of recursive type" from the Fortran 2008 summary document available at https://wg5-fortran.org/N1801-N1850/N1828.pdf and appended here: A recursive type is permitted to be based on al...

XLF: request support for -shared flag consistent with the XLC usage

The XLC compiler accepts the "-shared" flag as an alias to "-qmkshrobj" to create shared object (.so) files, but the XLF compiler does not. The XLF option -shared is not documented but is not identified as invalid when it is used. Using -shared do...

FORTRAN V2.6 for z/OS - Add Compiler Option to Force Explicit Variable Declarations

The Fortran compiler for z/OS does not have a compiler option to force all variables to be explicitly declared. Instead each and every program has to be coded with an IMPLICIT NONE statement. We would like a compiler option to force this instead o...

Support norm2 in XL Fortran 2008

As part of the Fortran 2008+ standards, norm2 is widely supported by various compiler toolchains. This RFE is to request support for the norm2 intrinsic be added to IBM XL Fortran 2008.
