This would have to be implemented in the library, so the effects of such a
patch would only matter in the code GCC generates when compiling the library.
IOW, I don't think this would be of much benefit here.

I'm trying to work on this.
I would prefer a syntax "open(...,convert="little_endian") or something like
that.

This wouldn't allow taking sources and data files from a big-endian platform
to a little-endian platform without either conversion of the data files or
modifications to the sources, so this will also have to be settable at runtime.

Many compilers, like the Intel and PGI ones for instance, simply have a
-byteswap flag that is set at compile time. That way any unformatted data that
is input or output is expected to be switched to Little or Big Endian all the
time. This is typically what we've needed over the years. I haven't really seen
a case to only byteswap certain files. A run time option would work as well as
long as people remember to set the environment variable or whatever.

ifort actually uses -convert big_endian or -convert little_endian to
supply defaults. This is better than specifying byteswapping,
because it is (if set) platform-independent.
We could also use environment variables the same way that ifort
does.
Three ways to specify the same thing... but I think there's a need
for that.

I imagine code from g95 could be leveraged to support this feature couldn't it?
This is a really important feature, especially in corporate environments where
there is usually mix of big-endian and little-endian machines. (Of course, the
current 64 bit record delimitters for unformatted files eliminates any hope of
interoperability with other fortran compilers.)

Rather not. The libraries have diverged pretty much so it is probably
easier to write this from scratch.

------- Comment #11 from tkoenig at gcc dot gnu dot org 2005-11-05 22:21 -------
OK, for the interface...
My suggestion would be to have three levels of supplying this value (ifort
has five or six :-)
First, an option to supply to the compiler. This could be
-fconvert=big_endian
-fconvert=little_endian
-fconvert=native (the default)
and maybe, at a later date,
-fconvert=vax_d
-fconvert=ibm_360.
This would be valid for all the units.
With this option alone, it would not be possible to write a conversion
program, so we need something else.
This could be overridden by a CONVERT="BIG_ENDIAN" etc. in the OPEN statement.
This, in turn, could be overridden by environment variables in the format
GFORTRAN_CONVERT_BIG_ENDIAN=10,20,30,40
GFORTRAN_CONVERT_LITTLE_ENDIAN=11,21,31,41
Agreed?
It would probably best to implement the compiler swith as selecting a
library at runtime. I'll leave that to a later date :-)
If anybody knows how to set an environment variable in a dejagnu
testcase, please tell :-)

Also, little_endian and big_endian have
to be converted to native or swap, depending on
the architecture.

Thomas,
I'm not in favor of environmental variables, which I think would
also be Paul Brook's position. It's too easy to have the variables
set or unset at the wrong time.
OTOH, you're working on a patch, so it's up to you.
What are your plans for REAL(10), REAL(16), INTEGER(16), COMPLEX(10),
and COMPLEX(16)? AFAIK, the reals may have padding issues.

------- Comment #15 from rrr6399 at futuretek dot com 2005-11-11 13:26 -------
I think the approach of having multiple ways of changing the behavior is a good
one. Many Unix programs do this kind of thing to allow the user to choose the
best way to accomplish the goal. I've found each approach useful in the past.
The environment variable approach also allows the same executable to be
used for different scenarios. The only negative I see is if the executable
was compiled by a different compiler (ifort, pgf95, etc.). A user might
expect that the behavior will change with an environment variable setting and
then wonder why it didn't. Perhaps the same environment variable names used by
ifort could be used by gfortran to limit this issue a bit?

In the docs, I would recommend setting them via
GFORTRAN_CONVERT_BIG_ENDIAN=3 progname
or
(setenv GFORTRAN_CONVERT_BIG_ENDIAN=3 ; progname )
> What are your plans for REAL(10), REAL(16), INTEGER(16), COMPLEX(10),

I don't have enough information about alignment to get
REAL(10) to work on a big-endian system. If we use those,
we also get bitten by the 12-byte/16-byte alignment issue for
different architectures. Does any big-endian architecture have
REAL(10)?

Ifort uses environment variables based on unit numbers, file extensions,
and I don't know what else. I'd hate to copy all that. Also,I'd
rather stick to the GFORTRAN_* namespace of environment variables.

I have a patch (attached), but it causes quite a number of

------- Comment #25 from tkoenig at gcc dot gnu dot org 2005-12-10 20:12 -------
The committed patch implements the basic functionality, via
the CONVERT keyword for open.
We still need different options to select this (via compile-time flags
and environment variables), so I'm leaving this bug open.

Created an attachment (id=10602)

proposed patch for environment variable
This implements setting the default for byte-swapping via an
environment variable.
Still needs documentation etc.

Strange. I don't see this with revision 110664 on i686-pc-linux-gnu,
and also nothing on
http://gcc.gnu.org/ml/gcc-testresults/2006-02/msg00430.html
http://gcc.gnu.org/ml/gcc-testresults/2006-02/msg00416.html
What system are you running on? What happens if you run this
test case directly?
Thomas
