Re: Sun compares their compiler tools to GNU tools

Such figures are meaningless.  Better performance on what?

There are cases where KAI C++ will have about 5x the performance of
either Sun CC or g++, and other cases where the performance is
exactly the same (KAI does C++ -> C so it is limited by the performance
of the C compiler you choose, which might be gcc or Sun C).

There are cases where egcs beats Sun CC and vice versa.  And how
should we measure the ratio of the vast number of valid C++ programs
that egcs compiles and Sun does not?
