FreePort Express translates any nonprivileged user executable that runs on SunOS Version 4.1. This description applies to nearly all application programs that run on SunOS Version 4.1. The section Translation criteria summarizes the criteria for executables that you can and cannot translate. Limitations for particular versions of the translator appear in FreePort Express Release Notes . FreePort Express should only be used to translate software that the user has the right to copy, translate and use on an Alpha system.
Translated code provides good performance, but ported code is better still.
In most cases, your better long term option is to port your application source code. The fpx command supports two sets of options. One set is for general use - these options specify input and output file names and request or suppress information. The other set is for special cases - these options affect translation or run time or help you debug a translated executable. For example, you can manipulate how the translator handles floating-point computations.
