Compatibility

Fortran For Machine Learning

In general, object code and modules compiled with earlier versions of Intel Fortran Compiler for Linux* (8.0 and later) may be used in a build with version 19.1. Exceptions include:

• Sources that use the CLASS keyword to declare polymorphic variables and which were built with a compiler version earlier than 12.0 must be recompiled.
• Objects built with the multi-file interprocedural optimization (-ipo) option must be recompiled with the current version.
• Objects that use the REAL(16), REAL*16, COMPLEX(16) or COMPLEX*32 datatypes and which were compiled with versions earlier than 12.0 must be recompiled.
• Objects built for the Intel® 64 architecture with a compiler version earlier than 10.0 and that have module variables must be recompiled. If non-Fortran sources reference these variables, the external names may need to be changed to remove an incorrect leading underscore.
• Modules that specified an ATTRIBUTES ALIGN directive outside of a derived type and were compiled with versions earlier than 11.0 must be recompiled. The compiler will notify you if this issue is encountered.
• Modules that specified an ATTRIBUTES ALIGN directive inside a derived type declaration cannot be used by compilers older than 13.0.1.
• The implementation of the Fortran 2008 submodules feature required extensive changes to the internal format of binary .mod files. Therefore module files created by the version 16.0 or newer Fortran compiler cannot be used with version 15.0 or older Fortran compilers.
• Objects built with Intel Fortran Compiler version 18.0 and earlier version of regcall calling convention must be recompiled with 19.0 or newer. Intel library libirng uses regcall. Version of this library shipped with 19.0 compiler version or newer is not compatible with older versions. regcall is implicitly used by following attribute:
  !DIR$ ATTRIBUTES [att,] VECTOR [:clause] [, att].. :: routine-name

Stack Alignment Change for REAL(16) and COMPLEX(16) Datatypes

In versions prior to 12.0, when a REAL(16) or COMPLEX(16) (REAL*16 or COMPLEX*32) item was passed by value, the stack address was aligned at 4 bytes. For improved performance, the version 12 and later compilers align such items at 16 bytes and expects received arguments to be aligned on 16-byte boundaries. This change is also compatible with gcc.

This change primarily affects compiler-generated calls to library routines that do computations on REAL(16) values, including intrinsics. If you have code compiled with earlier versions and link it with the version 12 libraries, or have an application linked to the shared version of the Intel run-time libraries, it may give incorrect results.

In order to avoid errors, you must recompile all Fortran sources that use the REAL(16) and COMPLEX(16) datatypes if they were compiled by compiler versions earlier than 12.0.

New and Changed Compiler Features

New features from Fortran 2018

• Enhancements to the IMPLICIT statement allow specifying that all external procedures must declared EXTERNAL
• Enhancements to the GENERIC statement permit it to be used to declare generic interfaces

• FAIL IMAGE statement allows debugging recovery code for failed images without having to wait for an actual image failure
• The named constants STAT_FAILED_IMAGE and STAT_UNLOCKED_FAILED_IMAGE have been defined in the intrinsic
  ISO_FORTRAN_ENV module
• An optional argument STAT= has been added to ATOMIC_REF and ATOMIC_DEFINE intrinsic procedures
• Optional STAT= and ERRMSG= specifiers have been added to the MOVE_ALLOC intrinsic procedure, to image selectors, and to the CRITICAL statement and construct
• Atomic subroutines ATOMIC_ADD, ATOMIC_AND, ATOMIC_CAS, ATOMIC_FETCH_ADD, ATOMIC_FETCH_AND, ATOMIC_FETCH_OR, ATOMIC_FETCH_XOR, ATOMIC_OR, and ATOMIC_XOR have been implemented
• Collective subroutines CO_BROADCAST, CO_MAX, CO_MIN, CO_REDUCE, and CO_SUM have been implemented
• The SELECT RANK construct has been implemented allowing manipulation of assumed rank dummy arguments
• The compiler will now diagnose the use of nonstandard intrinsic procedures and modules as required by Fortran 2018
• Transformational intrinsic functions from the intrinsic modules ISO_C_BINDING, IEEE_ARITHMETIC, and IEEE_EXCEPTIONS are now allowed in specification expressions
• You can now specify the optional argument RADIX for the IEEE_GET_ROUNDING_MODE and IEEE_SET_ROUNDING_MODE intrinsic module procedures
• The optional ROUND argument has been added to the IEEE_RINT function in the intrinsic module IEEE_ARITHMETIC
• The intrinsic module IEEE_ARITHMETIC now includes the functions IEEE_FMA, IEEE_SIGN_BIT, IEEE_NEXT_UP and IEEE_NEXT_DOWN
• The intrinsic module procedures IEEE_MAX, IEEE_MIN, IEEE_MAX_MAG, and IEEE_MIN_MAG have been implemented
• The intrinsic module procedures IEEE_INT and IEEE_REAL have been implemented
• The intrinsic module IEEE_EXCEPTIONS now contains a new derived type, IEEE_MODES_TYPE, which can be used to save and restore the IEEE_MODES using the IEEE_GET_MODES and the IEEE_SET_MODES intrinsic module procedures
• A new rounding mode, IEEE_AWAY has been added
• SUBNORMAL is now synonymous with DENORMAL
• IEEE_QUIET_EQ, IEEE_QUIET_NE, IEEE_QUIET_LT, IEEE_QUIET_LE, IEEE_QUIET_GT, IEEE_QUIET_GE, IEEE_SIGNALING_EQ, IEEE_SIGNALING_NE, IEEE_SIGNALING_GT, IEEE_SIGNALING_GE, IEEE_SIGNALING_LT, and IEEE_SIGNALING_LE intrinsic module procedures have been implemented

New features from OpenMP 5.0*

• IF clause on SIMD directive
• NONTEMPORAL clause on SIMD directive
• Inclusive/exclusive scan operations in SIMD and TARGET SIMD constructs.

Changed compiler behavior

• Previous compiler versions erroneously permitted a PRIVATE or SEQUENCE statement to appear prior to the declaration of any type parameters in a derived type declaration. Intel® Fortran Compiler 19.1 no longer permits this behavior.
• The INQUIRE statement now uses realpath’/’GetFullPathNameA’ and uses the resulting canonicallized file-paths if the calls succeeds. An example of the change is:
  Open file as “bar/foo”.
  Before:
  Inquire whether “./bar/foo”, “bar//foo” or “bar/./bar/foo” is open – it is not.
  After:
  Inquire whether “./bar/foo”, “bar//foo” or “bar/./bar/foo” is open – it is.
• In 19.0 compiler version, all procedures with the exception of C_F_POINTER from the intrinsic module ISO_C_BINDING were made PURE per the Fortran 2018 standard. Interpretation 18/007 declared that making C_F_PROCPOINTER PURE was a mistake. 19.1 complies with this interpretation and makes C_F_PROCPOINTER IMPURE.

New and Changed Compiler Options

Please refer to the compiler documentation for details. Following new compiler options added:

For a list of deprecated compiler options, see the Compiler Options section of the documentation.

-assume [no]old_inquire_recl

Fortran For Macs

Determines the value of the RECL= specifier on an INQUIRE statement for an unconnected unit or a unit connected for stream access.

-assume [no]old_ldout_zero

Determines the format of a floating-point zero produced by list-directed output. old_ldout_zero uses exponential format, no_old_ldout_zero uses fractional format.

-check [no]udio_iostat

Determines whether standard conformance checking occurs when user defined derived type input/output procedures are executed.-m[no-]branches-within-32B-boundaries

-m[no-]branches-within-32B-boundaries

Support Deprecated

The compiler option -stand f15 will be removed in next update. Use -stand f18 instead.

GNU* DBG support will be removed in the next update.

Support Removed

Loop Profiler

The Loop Profiler feature is removed in Intel® Fortran Compiler 19.1. The following compiler options related to Loop Profiler are removed: -profile-loops=keyword, -profile-loops-report=value -profile-functions, -guide-profile.

32-bit applications are no longer supported

Starting with the 19.0 release of the Intel® Fortran Compiler, macOS 32-bit applications are no longer supported.
If you want to compile 32-bit applications, you should use an earlier version of the compiler and Xcode* 9.4 or earlier. Wireless gaming controller for mac.

Fortran Integration into Xcode removed

Xcode integration capabilities within our Fortran Compiler bundle have been removed. Command line interface remains fully functional for macOS.

Keep in mind that installation of Xcode is still recommended, as command line tools from Xcode are required by the command line compiler. However, you can install just the Xcode Command Line Tools with this command from a terminal window:

Known Limitations

Slow License Checkout macOS 10.15

The license checkout performance on macOS Catalina 10.15 is roughly 1.1 seconds per source file. This is a 10x slowdown on this OS compared to previous versions of macOS. We are evaluating our license technology for a solution but at this time we have not root caused the issue. If this slowdown is an issue, please revert back to the previous macOS 10.14 where this slowdown does not occur.

Error 'no rule to process file' within Xcode* 10 and 11

macOS*’s XCode 10 and 11 come with a new build system and it is configured as the default. Currently, the Intel Fortran Compiler does not support it. You will see the error 'no rule to process file' when building an Intel Fortran Compiler project within XCode. Please switch to “Legacy Build System” in Project Settings to build your Fortran project in Xcode.

For more details please find this article.

Keep in mind, support for Xcode Integration is deprecated and will be removed in a future update - SEE THIS NOTE
