It is not such a good benchmark for that. There is a lot of code for
each benchmark that is not used. So the compilation time does not
really depend strongly on the complexity of the expressions.
But since you asked, it takes clang 3.0 between 4.3 and 4.6 seconds to
compile any one of the FTensor (not C-tran) benchmark files, gcc 4.7
takes between 3.9 and 4.7 seconds, and Intel between 6.4 and 7.4
