I had an internship at HP in the late 1980s. One of the people there
commented that, when gcc came out, it's code was (IIRC) 30% faster
than that of HPs compilers (for the 68k-based HP9000 computers running
HP/UX); a year later HPs compiler had caught up quite a bit. My guess
is that HP's compiler was PCC-based, and that optimization did not play
a big role in the Unix market until the arrival of RISCs and GCC.
Nowadays it plays too big a role for my taste (I prefer my programs to
work as intended).
