- Almost nonexistent optimization.


I'm under the impression that compilers spend most of their time with
optimization. TP did constant expression evaluation and dead code
elimination, but that's about all: no liveness analysis, no register
allocation. The resultant machine code was horrendous (but nobody
noticed or cared, even in the 16 MHz age - so much for the relevance
of efficiency).


That's Turbo Pascal. I never got around to looking at Borland Pascal
output - I sincerely hope things have improved.
