Known Limitations 
=================
The Intel Premier Support website <https://premier.intel.com/> contains 
more up to date information on errata and the availability of new versions 
of the compiler. 

The following are known defects in the Intel  Fortran Compiler, which might 
be fixed in a future version. 

work.pc file and parallel builds
================================

The work.pc file is used to store information about modules. This file is
shared by all compilations and there is no concurrency at lower than the
file level of granularity. This limits the ability to perform parallel makes.

New Functionality and Issues
============================

.Direct access files larger than 2 Gigabytes are now supported.

Fortran95 support. The Intel Fortran compiler supports all the features 
	of ISO Fortran 95, plus extensions.

.	The Intel Fortran Compiler includes many popular extensions from 
	other vendors' Fortran compilers, including VAX structures, CRAY 
	pointers, Sun IEEE FLAGS functions, and timing functions such as 
	ETIME and SECNDS. Please see the Programmer's Guide for more 
	information on supported extensions. 

Limitations with the Shared libraries on native
===============================================

Under certain conditions, when linking with shared libraries, the linker
produces the following message:
"ld: bfd assertion fail elf64-ia64.c:2852"

There are 2 scenarios when this message appears:
1. This is a warning message but an executable is generated which  
   sometimes does  not have execute permissions.  In most cases if the
   permissions are changed, the program  will execute correctly.   

2. This message is followed by a "core dump" from the linker (ld). 

This issue is being addressed in the updates to the Intel compilers.


Limitations and Tool Notes
==========================

The following are known defects in the Intel Fortran Compiler, 
which might be fixed in a future Version.

VAX(tm) FORTRAN style structures. Older programs may use a 
	feature introduced by Digital Equipment Corp.(tm) on the 
	VAX FORTRAN product, often referred to as "VAX structures". 
	This feature uses the keyword statements STRUCTURE, 
	RECORD, UNION, and MAP. Vax structures are supported for 
	compatibility with legacy code. ANSI FORTRAN-90 supplies an 
	equivalent feature, derived types. Since support for Vax 
	structures is intended to allow legacy code to compile, 
	Vax structures are not supported in FORTRAN-90 modules, and 
	you cannot use FORTRAN-90 style syntax in VAX structure 
	declarations. This restriction may be lifted in a future release. 
.	For example:
		PROGRAM MYPROG  
		STRUCTURE /MYSTRUCT/  
		INTEGER(4),DIMENSION(10)::I  
		END STRUCTURE  
		RECORD /MYSTRUCT/ MYVAR  
		END PROGRAM  
		MODULE MYMOD  
		STRUCTURE /MYSTRUCT/  
		INTEGER(4),DIMENSION(10)::I  
		END STRUCTURE  
		RECORD /MYSTRUCT/ MYVAR  
		END MODULE 

	You must either change the structure declaration to a FORTRAN-90 
	derived type, (this is the only option for MODULEs), or change 
	the declaration of the array to use ANSI 1978 FORTRAN style syntax, 
	such as INTEGER I(10)

.	The GETLOG function in the portability library, which can be 
	linked with the /4Yportlib switch, does not currently function 
	properly. Use of this function will result in an error, due to 
	not loading a particular dynamic link library. 

.	The TREAD function in the portability library is currently not 
	available.
