I could add a few more if you would like ;-)


What's their issue? Is there some kind of benchmark war going on
between different compilers? Where they want want to prove they can
produce the absolute fastest code possible, but only use single
threaded apps and screw those that must support multi-threaded
applications.

My phone and my camera have multicore systems. Single threaded is not
the way of the future. Which ever compiler makes it easier to write
multi-threaded applications is going to win, regardless of how well a
compiler can claim they optimize code the best for a single threaded
app.
