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