ECO KIT SUMMARY:
An ECO kit exists for DEC Fortran V6.2 for OpenVMS VAX on OpenVMS VAX
V5.4 or higher. This kit addresses the following problems:
Problems addressed in the FORTECO01062 Kit:
V6.2-109 The compiler no longer issues spurious VARUNUSED
diagnostics for a POINTER variable which is an actual
argument or in COMMON if one of its pointees is used.
V6.2-110 The compiler's checking for uninitialized variables
has been improved to include variables which have
not been selected for full analysis (a maximum of 128
variables are selected) but which have no stores in
the program unit.
V6.2-111 The compiler no longer allocates an unnecessary
longword of storage when a record array declaration
is seen.
V6.2-112 The compiler no longer improperly processes constants
of the form B'xxx', O'xxx', X'xxx' and Z'xxx' when
the constant string includes embedded blanks or
tabs (for example: X'123 45'). Also, the compiler no
longer issues a CHACONCONTD diagnostic if a constant
of the form 'xxx'X, etc. is continued across multiple
source lines.
V6.2-113 The compiler no longer fails with a bugcheck during
the LEXSYN phase when a logical-IF contains a
statement which would, if it appeared on its own,
cause an "unrecognized statement" error.
V6.2-114 The compiler no longer fails with a bugcheck during
the PACK phase when the following combination occurs:
1) Use of the SIN, COS, TAN, ATAN, LOG, LOG10, EXP or
SQRT intrinsics
2) The argument to the intrinsic is of a COMPLEX type
3) The compile command qualifiers /VECTOR and
/MATH_LIBRARY=FAST were both specified
Note that the /MATH_LIBRARY=FAST qualifier is
documented to have an effect for real datatypes only.
V6.2-115 The compiler no longer generates incorrect SCA
analysis data information for a main program which
begins with a DATA, DEFINE FILE, FORMAT or NAMELIST
statement. In addition, the compiler now generates
correct SCA typing information for variables whose
first appearance is in a NAMELIST statement which
occurs in the executable part of a program.
V6.2-116 The compiler no longer fails with a bugcheck
during the LEXSYN phase under extremely rare and
unpredictable circumstances while processing an
actual argument list.
V6.2-117 The compiler no longer fails with a bugcheck during
the LIFE phase for certain programs which have an
array reference as a DO-loop bound.
V6.2-118 The compiler no longer emits bounds checking code for
expanded BLAS routines, even if /CHECK=BOUNDS is in
effect. The bounds checking code interfered with the
common use of passing multiple-dimension arrays to
certain BLAS routines (for example, DSET).
V6.2-119 The compiler no longer generates incorrect code for
loading the argument to certain COMPLEX*16 intrinsic
functions such that the address of the argument was
overwritten by the real part of the argument.
Problems addressed in the FORTECO02062 Kit:
V6.2-120 The compiler now correctly flags as an extension the
use of the INTEGER*1, LOGICAL*2 and REAL*16 types
in an INTRINSIC statement when /STANDARD=MIA is in
effect.
V6.2-121 The compiler no longer fails with a bugcheck
during the FINAL phase when a %LOC function or
LOC intrinsic makes a recursive reference to the
enclosing subroutine or function when the generated
instruction for that reference is more than 128 bytes
away from the routine entry point. Also the compiler
now correctly issues the ROUREFREC diagnostic if
such recursive reference occurs but the /RECURSIVE
qualifier was not specified.
V6.2-122 The compiler no longer issues a USEUNIVAR for the
use of a character variable which was partially
defined by having had a substring passed as an actual
argument.
V6.2-123 The compiler no longer disallows the lowercase
letters 'a' through 'f' in prefix-style hexadecimal
constants (eg. X'123abc').
V6.2-124 The compiler now gives the ASSDOVAR warning if a DO-
loop control variable appears as an IOSTAT specifier
in an I/O statement inside a DO loop.
V6.2-125 The compiler now properly sign-extends bit constants
when used in contexts where they are treated as
INTEGER*2 or BYTE types.
NOTE: For further details, see Section 1.1.1.5 of the
release notes.
V6.2-126 The compiler no longer gives an INVLEXEME error when
a record field array is used as the buffer in an
ENCODE or DECODE statement.
V6.2-127 The compiler no longer fails with a bugcheck during
the CODE phase for certain programs which use inlined
BLAS intrinsics and are compiled /CHECK=BOUNDS.
V6.2-128 The compiler now emits the correct DEBUG symbol table
information for untyped (non-Fortran-77) PARAMETER
constants whose value is a bit constant longer than
32 bits so that these values may be evaluated during
a DEBUG session.
V6.2-129 The compiler now supports /DEBUG=PARAMETERS=NONE. If
this is specified, no PARAMETER constants are written
to the debug symbol table. Note that /DEBUG=NOSYMBOLS
prevents any debug symbol information, including
PARAMETER constants, from being written.
V6.2-130 The compiler now supports the command line keywords
/WARNINGS=[NO]INFORMATIONAL and /ASSUME=[NO]SOURCE_
INCLUDE.
V6.2-131 The compiler no longer fails with a bugcheck during
the CODE phase when a pointee non-adjustable array is
passed by descriptor.
V6.2-132 The compiler no longer issues a VARUNUSED diagnostic
for pointees.
INSTALLATION NOTES:
The system/cluster does not need to be rebooted after this kit is
installed.
If this kit is being installed on a VMScluster system, the command
procedure SYS$UPDATE:FORTRAN$POST_INSTALL.COM must be run on every VAX
member of the cluster so that the updated compiler and command tables
are available to all users.
