I've put up ptc on our machine, which is a 780 with a pcc-derived C compiler and Berkeley Pascal. I think that this is a pretty common configuration, so I thought others with a similar setup might like to know that ptc will serve them as a good Pascal optimizer, producing 15% improvement in speed and 30% in text size. Here are the numbers (cptc.c is ptc.p's output, when executed on itself): $ ls -l cptc.c ptc.p -rw-r--r-- 1 john s 247609 Aug 5 02:52 cptc.c -rw-r--r-- 1 john s 216865 Aug 5 01:33 ptc.p $ time ptc <ptc.p >1.c 685.5u 47.7s 889r ptc $ time cptc <ptc.p >2.c 592.6u 42.0s 736r cptc $ cmp 1.c 2.c $ size ptc cptc text data bss dec hex 156672 20480 10308 187460 2dc44 ptc 108544 17408 10948 136900 216c4 cptc John Mackin, Basser Department of Computer Science, University of Sydney, Sydney, Australia john@basser.oz.AU (john%basser.oz@SEISMO.CSS.GOV) {seismo,hplabs,mcvax,ukc,nttlab}!munnari!basser.oz!john
