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.
