/* perform_an_assembly_pass()
*
* Here to attempt 1 pass over each input file.
* We scan argv[*] looking for filenames or exactly "" which is
* shorthand for stdin. Any argv that is NULL is not a file-name.
* We set need_pass_2 TRUE if, after this, we still have unresolved
* expressions of the form (unknown value)+-(unknown value).
*
* Note the un*x semantics: there is only 1 logical input file, but it
* may be a catenation of many 'physical' input files.
