ic960 and Environment Variables

Environment variables specify default directories for input files,
temporary files, libraries, the assembler, and the linker. In addition, the
environment variable specifies the default architecture. The
I960ARCH
compilation system uses the following environment variables to set
defaults:
I960ARCH
I960BASE

processor for code generation. The possible
