I would hesitate to make any broad statements about efficiency of compilers.
The proper thing to do here is to create meaningful representative tests
from your nameless client's code and do actual tests to find out about
performance.
Intel has always been pretty good at creating compilers that do well on
standard benchmarks, but that does not necessarily translate into meaning
that they will do well on your code (look for example at the experiences
with the i860).
The issue after all is not whether the ia64 compiler performs as well as
it could, but rather whether it performs well enough to meet your client's
requirements. Those are very different things in two directions:
a) it may be that no compiler performs well enough to meet these
requirements even if it generates optimal code.
b) it may be that a compiler generating less than optimal code is
nevertheless sufficiently efficient to be usable.
