- $! 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).
- $!
- $! 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.
- $!
- $! If you do not specify which compiler you want to build, it is assumed that
- $! you want to build GNU-C ("CC1").
- $!
- $! Now figure out what we have been requested to do.

- Note: GCC 2.0 treats external variables differently than GCC 1.40 does.
- Before you use GCC 2.0, you should obtain a version of the assembler which
- contains the patches to work with GCC 2.0 (GCC-AS 1.38 does not contain
- these patches - whatever comes after this probably will). The assembler
- in gcc-vms-1.40.tar.Z from prep does contain the proper patches.
-
- If you do not update the assembler, the compiler will still work,
- but `extern const' variables will be treated as `extern'. This will result
- in linker warning messages about mismatched psect attributes, and these
- variables will be placed in read/write storage.
