That is right, but the discussion is about using a certain language
because there exists a very optimizing compiler for that language.
As there is no Intel compiler for Ada, and the Intel compilers provide
superior performance than GCC, it is not logical to switch from Pascal
to Ada if Pascal isn't fast enough for you.
Further, it is unknown how well the GCC backend optimizes Ada language
constructs as it is primarily designed for the C language. This problem is
at least present in the GNU Fortran compiler; while GCC gives very
reasonable performance for C code, the code from the Fortran compiler is
awfull.
