| 2 | * f77.c |
| 3 | * |
| 4 | * Driver program for the 4.2 BSD f77 compiler. |
| 5 | * |
| 6 | * University of Utah CS Dept modification history: |
| 7 | * |
| 8 | * $Log: f77.c,v $ |
| 9 | * Revision 1.14 85/03/01 00:07:57 donn |
| 10 | * Portability fix from Ralph Campbell. |
| 11 | * |
| 12 | * Revision 1.13 85/02/12 19:31:47 donn |
| 13 | * Use CATNAME to get the name of a concatenation command instead of |
| 14 | * explicitly running 'cat' -- you can get the wrong 'cat' the old way! |
| 15 | * |
| 16 | * Revision 1.12 85/01/14 06:42:30 donn |
| 17 | * Changed to call the peephole optimizer with the '-f' flag, so that |
| 18 | * floating point moves are translated to integer moves. |
| 19 | * |
| 20 | * Revision 1.11 85/01/14 04:38:59 donn |
| 21 | * Jerry's change to pass -O to f1 so it knows whether the peephole optimizer |
| 22 | * will be run. This is necessary in order to handle movf/movl translation. |
| 23 | * |
| 24 | * Revision 1.10 85/01/14 03:59:12 donn |
| 25 | * Added Jerry Berkman's fix for the '-q' flag. |
| 26 | * |
| 27 | * Revision 1.9 84/11/09 01:51:26 donn |
| 28 | * Cosmetic change to stupid() suggested by John McCarthy at Memorial |
| 29 | * University, St. Johns. |
| 30 | * |
| 31 | * Revision 1.8 84/09/14 16:02:34 donn |
| 32 | * Added changes to notice when people do 'f77 -c foo.f -o bar.o' and tell |
| 33 | * them why it doesn't do what they think it does. |
| 34 | * |
| 35 | * Revision 1.7 84/08/24 21:08:31 donn |
| 36 | * Added call to setrlimit() to prevent core dumps when not debugging. |
| 37 | * Reorganized the include file arrangment somewhat. |
| 38 | * |
| 39 | * Revision 1.6 84/08/24 20:20:24 donn |
| 40 | * Changed stupidity check on Jerry Berkman's suggestion -- now it balks if |
| 41 | * the load file exists and has a sensitive suffix. |
| 42 | * |
| 43 | * Revision 1.5 84/08/15 18:56:44 donn |
| 44 | * Added test for -O combined with -g, suggested by Raleigh Romine. To keep |
| 45 | * things simple, if both are specified then the second in the list is thrown |
| 46 | * out and the user is warned. |
| 47 | * |
| 48 | * Revision 1.4 84/08/05 21:33:15 donn |
| 49 | * Added stupidity check -- f77 won't load on a file that it's asked to |
| 50 | * compile as well. |
| 51 | * |
| 52 | * Revision 1.3 84/08/04 22:58:24 donn |
| 53 | * Improved error reporting -- we now explain why we died and what we did. |
| 54 | * Only works on 4.2. Added at the instigation of Jerry Berkman. |
| 55 | * |
| 56 | * Revision 1.2 84/07/28 13:11:24 donn |
| 57 | * Added Ralph Campbell's changes to reduce offsets to data. |
