Well, there don't seem to be any 64-bit literals in my code, so it's probably not just a problem with literals. There certainly are a lot of 64-bit registers and 64-bit parameters. Would it be a problem with 64- bit parameters? Should I change my parameter-passing convention to avoid 33-bit and longer parameters, possibly passing them by reference? -- hendrik _______________________________________________ Cminusminus mailing list [email protected] https://cminusminus.org/mailman/listinfo/cminusminus
