22.4.2 SDE Compatibility Macros

The MIPS^® SDE (Software Development Environment) defines a number of macros, most with the prefix “_MIPS_”, which characterize various target specific options, some determined by command line options (for example, -mint64). Where applicable, these macros will be defined by the compiler in order to ease porting applications and middleware from the SDE to the compiler.
