hi
is there an option to treat all float variables (32bit) to
double (64bit) on a 64bit machine? I found -mdouble-float,
but I got error message
    cc1: error: unrecognized command line option "-mdouble-float"
not sure why.
appreciated if anyone can commend. thanks

Qianqian
That option is only supported on a MIPS processor. Are you compiling on a MIPS processor?


no, it's an Intel Core2Duo. is there anything can do this
beside "typedef double MyFloat" and replace all "float" in
my source codes?

thanks
