Annotation of 41BSD/cmd/mip/fconvert, revision 1.1.1.1

1.1       root        1: In an attempt to speed up the Fortran 77
                      2: compiler, we have provided a new interface between
                      3: the fortran compiler and the portable C compiler.
                      4: The intermediate file is binary, and the result is
                      5: to speed up the execution of Fortran considerably.
                      6: The changes necessary to make this work are as follows:
                      7: 
                      8: ***    The ONEPASS flag should be off for Fortran;
                      9:        the simplest way of making this happen is to take
                     10:        the line # define ONEPASS on macdefs, and put a
                     11:        # ifndef FORT ... # endif around it.
                     12: 
                     13: ***    The function label from pass 1 must be put in
                     14:        a file, fort.h.  Also,  a simple function, tlabel,
                     15:        must be written to copy names and make labels.
                     16: 
                     17: ***    The function `where' must be defined, as well as the
                     18:        function main (which was once on local2.c).
                     19:        They can be defined on fort.h, or on local2.c
                     20:        (surrounded by # ifnded ONEPASS and # endif)
                     21: 
                     22: ***    Other things from pass one may have crept into the pass 2
                     23:        code: they must be also done, either on fort.h or
                     24:        on local2.c surrounded by ifdefs.
                     25: 
                     26: ***    make fort  then creates the fortran interface...
