Compiler optimization for fastest possible code

I would like to select the compiler optimizations to generate the fastest possible application.

Which of the following settings should I set to true?

Dead store elimination
Eliminate duplicate expressions within basic blocks and functions
Enable loop induction variable and strength reduction
Enable Pentium instruction scheduling
Expand common intrinsic functions
Optimize jumps
Use register variables

There is also the option 'Generate the fastest possible code.', which I have obviously set to true. However, when I set this to true, all the above options are still set at false.

So I would like to know if any of the above options will speed up the application if I set them to true?

I know some will hate me for this, but nobody here can answer you truthfully. You have to try your program with and without them, and profile each build and see what the results are. Guess-work won't get anybody anywhere.

Compilers already do tons(!) of great optimization, with or without your permission. Your best bet is to write your code in a clean and organized matter, and worry about maintainability and extensibility. As I like to say: Code now, optimize later.
