I believe Thompson reports code quality comparable to e.g., GNU CC, and in
any case the original poster was asking about compilation for a debugging
environment, where code quality is less important. You have to be careful
about your target audience!


As an aside, the IBM PL.8 compiler did particularly naive code generation
when optimization was off. The total compile time went down with
optimization on! That was because the naive code was so much larger and
the reduced I/O and assembly costs paid for the cost of optmization.
