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
