First we figure out what needs to be done. This is sort of like a limited +$! make facility - the command line options specify exactly what components +$! we want to build. The following options are understood: +$! +$! LINK: Assume that the object modules for the selected compiler(s) +$! have already been compiled, perform link phase only. +$! +$! CC1: Compile and link "C" compiler. +$! +$! CC1PLUS:Compile and link "C++" compiler. +$! +$! CC1OBJ: Compile and link objective C compiler. +$! +$! ALL: Compile and link all of the CC1 passes. +$! +$! INDEPENDENT: +$! Compile language independent source modules. (On by default). +$! +$! BC: +$! Compile byte compiler source modules. (On by default). +$! +$! OBJCLIB: +$! Compile Objective-C run-time library. +$! +$! DEBUG: Link images with /debug. +$! +$! If you want to list more than one option, you should use a spaces to +$! separate them. +$! +$! Any one of the above options can be prefaced with a "NO". For example, +$! if you had already built GCC, and you wanted to build G++, you could use the +$! "CC1PLUS NOINDEPENDENT" options, which would only compile the C++ language +$! specific source files, and then link the C++ compiler. +$! +$!
