I use them for "number crunching" (in my case constructive
enumeration of graphs). The 8c compiler does some optimization,
even though it has no '-O' flag. I found that on x86, the speed is
comparable to that of 'gcc -O2'. The performance gain
with 'gcc -O[34]' is minimal in my case.
The compilation speed of 8c is unbeaten.
