ECO KIT SUMMARY:
An ECO kit exists for FORTRAN V5.2 on UNIX V4.0 - V5.0. This kit
addresses the following problems:
Problems Addressed in the FORTAUE01052 Kit:
This kit contains an update of DIGITAL Fortran V5.2 (including Fortran
95/90 and Fortran 77 compilers and the DIGITAL Extended Math Library) to
correct problems discovered in the compilers and run-time library since
the V5.2 release. You must have DIGITAL Fortran V5.2 installed before
installing this update.
o The following changes were made to the Fortran 95/90 compiler:
- Correct a problem with PACK when the first argument is a
two-dimensional slice of a three-dimensional array.
- Correct problem with ADJUSTL, ADJUSTR and COTAN with array
element arguments.
- Fix internal compiler error for certain uses of LL* intrinsics.
- Prevent internal compiler error when the size of a return value
is based on a call to a pure function with the argument to this
function.
- Correct problems with nested uses of SPREAD intrinsic.
- Make ASSOCIATED return the correct result when the target is an
element of a deferred-shape array.

with non-zero base, e.g., TRANSFER(X, CH(I1:I2))

bad code.
- Correct problem with pointer assignment when the
right-hand-side is an array of derived types.

- Eliminate spurious warning when passing a POINTER or
assumed-shape array in COMMON to a routine with a compatible
dummy argument declaration.

with entry points.

aliasing case involving an EQUIVALENCEd variable passed as an
argument.

specification expressions.

modules define the symbol but one has marked it PRIVATE.

specified.

different types.

in ASSOCIATED.
- When -names:as_is specified, don't make IMPLICIT case-sensitive.

certain cases involving renaming.

statement as an actual argument without an EXTERNAL statement or
explicit interface.
- Eliminate spurious overflow message for MS-style base-2 constant.
- Correct problem with generic routine matching.
- Correct internal compiler error when function return value used
in statement function expression.
o The following changes were made to the Fortran 77 compiler:
- Do not issue an alignment warning for variables equivalenced into
a common block seen inside a cdec$ OPTION /warn=noalign.
- A USEROPEN routine may have side effects (modify COMMON variables).
- Get better optimizations for READ/WRITEs which do NOT modify
variables like ASSOCIATE_VARIABLES or through USEROPEN routines.
- Fix -convert to take ONLY its most recent argument (so that
command line overrides any DECFORT_INIT settings.
- Avoid ACCVIO when RECORD statement conflicts with previous use of
name.
o The following changes were made to the f77 driver:
- Link against libm_ev6.a for "-arch ev6" plus "-non_shared".
o The following changes were made to the run-time support:
- A memory leak was fixed in the run-time support when a list
directed read that used a run-time format encountered a
conversion error.
- For direct and keyed access formatted read operations where the
input list and format specification require more data than the
input record contains and with F90 input padding required, the
run-time library did not properly handle character string input
- The Fortran runtime was writing past the end of an internal
string in the support routine for PAUSE with the potential of
generating an access violation or segmentation fault.
- List-directed READ's of a large file could sometimes cause an
access violation in the Fortran runtime library.
- CPU_TIME was returning a negative value if the cpu time was
greater than 36 minutes. This problem has been fixed by using
the GETRUSAGE system routine instead of the C clock routine to
obtain the process time.
- Under some situations, the performance when writing out very
large amounts of data using formatted output has been improved.
- When performing a list directed read of a character variable and
the next character being read in is an asterisk "*", the run-time
support was interpreting the asterisk as a repeat character. The
proper interpretation is that it is the start of a non-delimited
string. The run-time support was modified to provide the proper
interpretation.
- If -check nooutput_conversion was specified or defaulted, the
run-time library did not totally ignore an output conversion
error. It only inhibited the outputting of the run-time
diagnostic message when a conversion error occurred. Any IOSTAT=
variable was still set to reflect the error (63) and any ERR=
branch was still taken. When an output conversion error occurs
now with /check:nooutput_conversion specified, the run-time
library will fill the output field with asterisk's (as before)
and continue as if no error occurred, i.e., any ERR= branch will
not be taken and any IOSTAT= variable will reflect success.
- The run-time support was not properly advancing to a new record
when format reversion was in affect when ADVANCE='NO' was
specified. The RTL support was modified to properly advance to
the next record under these circumstances and now adheres to the
Fortran 95 Language standard.
o The following changes were made to the DIGITAL Extended Math Library:
Changes were made to the following BLAS routines to eliminate
undeserved segmentation faults:
SGER, DGER, CGERC, CGERU, ZGERC, ZGERU
Changes were made to the following LAPACK routines to eliminate
undeserved segmentation faults:
SSBEVX, SSPEVX, SSTEBZ, SSTEVX, SSYEVX
DSBEVX, DSPEVX, DSTEBZ, DSTEVX, DSYEVX
CHBEVX, CHEEVX, CHPEVX
ZHBEVX, ZHEEVX, ZHPEVX
Users can now include DXMLDEF.FOR in a free-format Fortran 90
compilation.
Users can now safely include dxmldef.h multiple times in a single
compilation. It may also be included in a C++ compilation.
