/*
* f77.c
*
* Driver program for the 4.2 BSD f77 compiler.
*
* University of Utah CS Dept modification history:
*
* $Log: f77.c,v $
* Revision 5.4 85/12/17 19:12:14 donn
* Dynamically allocate buffer; add lint fixes.
*
* Revision 5.3 85/11/25 00:00:02 donn
* 4.3 beta
*
* Revision 5.2 85/08/10 05:16:14 donn
* Ifdeffed 66 code, added -r8 flag. From Jerry Berkman.
*
* Revision 5.1 85/08/10 03:32:12 donn
* 4.3 alpha
*
* Revision 1.14 85/03/01 00:07:57 donn
* Portability fix from Ralph Campbell.
*
* Revision 1.13 85/02/12 19:31:47 donn
* Use CATNAME to get the name of a concatenation command instead of
* explicitly running 'cat' -- you can get the wrong 'cat' the old way!
*
* Revision 1.12 85/01/14 06:42:30 donn
* Changed to call the peephole optimizer with the '-f' flag, so that
* floating point moves are translated to integer moves.
*
* Revision 1.11 85/01/14 04:38:59 donn
* Jerry's change to pass -O to f1 so it knows whether the peephole optimizer
* will be run. This is necessary in order to handle movf/movl translation.
*
* Revision 1.10 85/01/14 03:59:12 donn
* Added Jerry Berkman's fix for the '-q' flag.
*
* Revision 1.9 84/11/09 01:51:26 donn
* Cosmetic change to stupid() suggested by John McCarthy at Memorial
* University, St. Johns.
*
* Revision 1.8 84/09/14 16:02:34 donn
* Added changes to notice when people do 'f77 -c foo.f -o bar.o' and tell
* them why it doesn't do what they think it does.
*
* Revision 1.7 84/08/24 21:08:31 donn
* Added call to setrlimit() to prevent core dumps when not debugging.
* Reorganized the include file arrangment somewhat.
*
* Revision 1.6 84/08/24 20:20:24 donn
* Changed stupidity check on Jerry Berkman's suggestion -- now it balks if
* the load file exists and has a sensitive suffix.
*
* Revision 1.5 84/08/15 18:56:44 donn
* Added test for -O combined with -g, suggested by Raleigh Romine. To keep
* things simple, if both are specified then the second in the list is thrown
* out and the user is warned.
*
* Revision 1.4 84/08/05 21:33:15 donn
* Added stupidity check -- f77 won't load on a file that it's asked to
* compile as well.
*
* Revision 1.3 84/08/04 22:58:24 donn
* Improved error reporting -- we now explain why we died and what we did.
* Only works on 4.2. Added at the instigation of Jerry Berkman.
*
* Revision 1.2 84/07/28 13:11:24 donn
* Added Ralph Campbell's changes to reduce offsets to data.
*
