Hello,


About the scimark2 benchmark that i did on FreePascal and Delphi and GCC,
i have used the following command to compiler:

gcc -O1 -S


i have used the -S flag to generate the assembler source code,
and i have looked at the assembler source code and i have noticed that 
effectivly GCC do auto-vectorize the code, it uses SSE2 instructions to 
vectorize the floating point calculations even with only the -O1 
optimization, this is why GCC is 2X times faster than FreePascal and 
Delphi on some scimark2 benchmarks that use floating point calculations.


Thank you,
Amine Moulay Ramdane.
