[fpc-pascal] Floating Point Performance on Intel

[Jan Ruzicka]

Sorry for previous reply.
I overlooked use of the index variable X.

Which C compiler are you comparing the FPC with?
GCC, MSVC, CC (include version please)
Some compilers have a function optimization, some have just a statement 
optimization.

Could you post a whole example?
The whole program would prevent misunderstanding.
As your program could be rewritten using B as constant or
the inner loop as :
  A := (A + X) * B;

How are you measuring the time?
