I have a desktop with a 64bit AMD x4 Phenom processor. I have noticed
that FreePascal programs perform worse on this computer then they do on
my 32 bit laptop. Integer performance seems to be about 3 times worse
then on the laptop. Now if I convert the pascal source to c and compile
that as follows:
gcc -O3 -funroll-all-loops -o MyExecutable MySource.c
The performance is many times better then with FreePascal. I assume
that gcc is compiling to 64 bit here and generating an optimizing for
the AMD processor. Is there a way to do something similar with Free Pascal?
