SUN Solaris (SPARC) gcc Compile Options ?

[OhNoNotAgain]

Hello all,

I have developed some code on a SUN Solaris 9 Sparc box, I want to produce a binary from this code that will also execute on Solaris 7 & 8 boxes and on both 32 and 64 bit machines.

I am using gcc to compile the code, can I have some recommendations on the best compile options to use please.

Thanks all.

Why the need to run the same executable on so many different machines. It's sure to be a big compromise between the bottom end and the top end.

Or put another way, why can't you compile different executables (from the same source) with the compiler flags tuned for that particular architecture.
