| Description |
|
The XL Fortran compiler continues to deliver additional functionality and enhancements, especially in the areas of performance and optimization, support for language enhancements, and support for new processors.
Support for the new POWER6 processors
With V11.1, the XL Fortran compiler exploits, optimizes, and tunes for the latest POWER6 processors. XL Fortran V11.1 expands the list of -qarch and -qtune suboptions to support the newly-available POWER6 processors.
Enhanced support for Fortran 2003
Beginning with the V8.1 release, XL Fortran delivered many Fortran 2003 standard features, including:
- BIND(C) for portable interoperability with C code
- Allocatable objects beyond just Fortran 95 arrays
- Stream I/O support
- ASSOCIATE and ENUM statements
- READ with BLANK= and PAD= specifiers
- WRITE with DELIM= specifier
- IEEE and Fortran environment modules
XL Fortran V11.1 builds on this work and adds significant Fortran 2003 enhancements which include:
-
Implementation of the full Fortran 2003 object-oriented programming model, including:
- Type extension
- Type-bound procedures
- Type finalization
- Polymorphism and runtime type determination, including the SELECT TYPE construct
- Abstract and generic interfaces
- Declaration of abstract types and deferred bindings
- PASS attribute
-
I/O enhancements
- User-defined derived type I/O
- New I/O specifiers, including SIGN= and DECIMAL= (DC and DP edit descriptors)
- Asynchronous I/O as defined by Fortran 2003, including the WAIT statement
- User-specified control of rounding during format conversion using the ROUND= specifier and new edit descriptors
- Handling of IEEE infinity and non-a-number in REAL and COMPLEX editing
- Support of PAD= specifier on INQUIRE operations
-
Scoping and data manipulation enhancements
- Renaming of defined operators on USE statements
- Fortran 2003 VOLATILE statement
- MAX, MIN, MAXLOC, MINLOC, MAXVAL, and MINVAL intrinsics for character types
- COMPLEX literals
- Pointer assignment and initialization expression enhancements
- Improved structure constructors
- Allocatable enhancements, including resizing on assignment and MOVE_ALLOC intrinsic
- Explicit type specification in an array constructor
-
Procedure enhancements
- Generic bindings for interfaces, defined operators, and defined assignment
- VALUE attribute for characters of length greater than one and derived types with allocatable components
- Procedure pointers, procedure declaration statement, and procedure pointers as derived type components
- Generalization of the MODULE PROCEDURE statement
- Deferred CHARACTER length
-
Intrinsic function enhancements
- Allow REAL type for COUNT_RATE argument of SYSTEM_CLOCK
- Allow boz-literal constants on INT, REAL, CMPLX, and DBL intrinsics
- Allow a new KIND argument on all instrinsics mandated by Fortran 2003
- Return signed zero results from the ATAN2, LOG, and SQRT intrinsics
- Add SELECTED_CHAR_KIND intrinsic
-
Other enhancements
- Enhanced STOP statement
- Increased the maximum number of continuation lines
The following new invocation commands are introduced in XL Fortran V11.1 to instruct the compiler to more closely adhere to Fortran 2003 language standards when compiling your applications:
- xlf2003
- xlf2003_r (for threaded applications)
- f2003
Architecture and processor support
The -qarch and -qtune compiler options control the code generated by the compiler. These compiler options adjust the instructions, scheduling, and other optimizations for a specified target processor or range of processors.
New default setting for -qarch, -qtune
- -qarch=ppc
- -qtune=balanced
The -qtune=balanced suboption is new for this release and becomes the default -qtune setting when certain -qarch settings are specified. Using -qtune=balance instructs the compiler to tune generated code for optimized performance across a range of recent processor architectures, including POWER6.
New compiler options for POWER6 processors
- -qarch=pwr6
- -qarch=pwr6e
- -qtune=pwr6
The -qipa compiler option also adds a new architecture cloning suboption, -qipa=clonearch=pwr6, to support interprocedural analysis (IPA) optimizations on POWER6 processors.
Additional enhancements
- XL Fortran V11.1 introduces many new performance-related compiler options and directives.
- New directives for this release include PowerPC cache control and POWER6 prefetch extensions and cache control.

XL Fortran Advanced Edition for Linux, V11.1 is part of the family of IBM compilers that support a number of platforms. It joins XL C Enterprise Edition for AIX® and XL C/C++ Enterprise Edition for AIX on System p, XL C/C++ Advanced Edition for Linux and XL Fortran Advanced Edition for AIX on System i™ and System p, XL C/C++ for z/OS®, ILE C/C++ for OS/400® on System i, and C/C++ for z/VM®. The code base for all of these compilers (C, C++, and Fortran) is the same. This facilitates source-level portability of your applications from these platforms to Linux.
XL Fortran now supports a majority of the Fortran 2003 standard. The following programming language specifications for Fortran are supported:
- ISO/IEC 1539-1:1991(e) and ANSI X3.198-1992 (referred to as Fortran 90 or F90)
- ISO/IEC 1539-1:1997 (referred to as Fortran 95 or F95)
-
Extensions to the Fortran 95 standard
- Industry extensions that are found in Fortran products from various compiler vendors
- Extensions specified in SAA® Fortran
- The majority of the Fortran 2003 standard, except for derived type parameters, but including object-oriented programming
- Common Fortran language extensions as defined by other compiler vendors, in addition to those defined by IBM
In addition to the standardized language levels, XL Fortran supports language extensions, including:
- OpenMP V2.5 extensions to support portable parallelized programming
- Language extensions to support vector programming
With representation from the IBM compiler development team on the Fortran language standards committee and on the OpenMP industry specifications committee, IBM is in a position to understand the latest updates, clarifications, and recommendations to the Fortran and OpenMP standards. Support of programming language standards allows for portability of your source code among a variety of compiler implementations.
