------- 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 :-) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23815
