Based on mature compiler technology from IBM, XL Fortran Enterprise
Edition version 9.1 for IBM Linux on Power™ features:
- Compliance
with FORTRAN 77, Fortran 90, and Fortran 95 language standards.
- Partial draft Fortran 2003 standard
support, including allocatable components, IEEE floating point
exception handling, pointer with INTENT attribute, VALUE attribute,
and PROTECTED attribute.
- Ability to generate code specifically
optimized for the Apple Power Macintosh G5.
- Support large memory sizes over 2 GB.
- Ability to use gdb to debug programs.
- Features specific to the IBM Power™
IBM Linux on Power™ environment, including support for:
- Xcode integration.

the native IBM Linux on Power™ help architecture.
- Industry-leading optimization and
performance, using tools and compiler options developed and proven
on previous XL Fortran compilers, including:
- Various levels of the -O compiler
option, that you can use to select mild to very aggressive
program optimization, including the invocation of some or
all of the compiler optimization options that follow below.
- -qpdf compiler option to enable
Profile-Directed Feedback, which can use results from sample
program execution to fine tune optimizations in conditional
branches and frequently-executed code sections.
- -qipa compiler option to enable
the Interprocedural Analysis tool, which can help the compiler
optimize across multiple source files on a "whole-program"
basis.
- -qarch, -qtune, and -qcache compiler
options that let you tune your application to specific processor
architectures and environments.
- -qhot compiler option that enables
high-order transformations to improve the performance of loops
in your program.
- Interlanguage calls between Fortran
and C/C++ programs, including code compiled with XL C/C++ Enterprise
Edition for IBM Linux on Power™, let you include C and C++ code segments
in your Fortran programs and Fortran code segments in your C and
C++ programs.

The IBM
XL Fortran Enterprise Edition compiler for IBM Linux on Power™ is a high performance F95
compiler based on the mature compiler technology of IBM XL Fortran
for AIX. The version designed for IBM Linux on Power™ is provided as a command
line compiler and generates very fast Fortran code for IBM Linux on Power™. Copies
purchased from Absoft include the full XL Fortran Enterprise Edition version 9.1 for IBM Linux on Power™
plus the Absoft Fx2™
Debugging Solution and technical support at no additional
charge.
The full American National Standard Fortran 90 language (referred
to as Fortran 90 or F90), defined in the documents American National
Standard Programming Language Fortran 90, ANSI X3.198-1992 and Information
technology - Programming languages - Fortran, ISO/IEC 1539-1:1991(E).
This language has a superset of the features found in the FORTRAN
77 standard. It adds many more features that are intended to shift
more of the tasks of error checking, array processing, memory allocation,
and so on from the programmer to the compiler.
The full ISO Fortran 95 language standard (referred to as Fortran
95 or F95), defined in the document Information technology - Programming
languages - Fortran - Part 1: Base language, ISO/IEC 1539-1:1997.
The XL Fortran Enterprise Edition compiler helps you port or migrate source code among
Fortran compilers by providing full Fortran 90 and Fortran 95 language
support. Selected language extensions (intrinsic functions, data
types, and so on) from many different compiler vendors are also
provided. To protect your investments in FORTRAN 77 object code,
you can link Fortran 90 and Fortran 95 programs with existing FORTRAN
77 object modules and libraries. To make programming and porting
easier, XL Fortran Enterprise Edition Version 9.1 provides common industry extensions
not found in Fortran 95.

Source-code conformance checking
To help you find anything in your programs that might cause problems
when you port to or from different FORTRAN 77, Fortran 90, or Fortran
95 compilers, the XL Fortran compiler provides options that warn
you about features that do not conform to certain Fortran definitions.

XL Fortran Enterprise Edition is shipped as a command line
compiler and was derived from IBM's family of compilers for AIX.
Features a wide range
optimizing features that let you generate highly-optimized 32- or 64-bit application code
to run efficiently on a wide variety of processors and processor families, or you can opt
to tune generated code to run most efficiently on a specific processor or processor family.
Not only exploits the capabilities of the IBM PowerPC, POWER3, and POWER4 processor architectures, but also adds support for the new POWER5 processor architecture.
XL Fortran Advanced Edition for Linux also includes a complete implementation of the OpenMP C/C++ API, Version 2.0. You can use OpenMP APIs to take advantage of improved program performance potential on machines featuring multiple processors.
