For instance, "ppc i386". If the current machine 11# isn't in the list, it will (effectively) be added. 12# FIXME: HOSTS is not used in this script. Use it or Remove it. 13HOSTS="$1" 14 15# The second parameter is a space-separated list of the architectures the 16# compilers will generate code for. If the current machine isn't in the list, a 17# compiler for it will get built anyway, but won't be installed. 18TARGETS="$2" 19 20# The third parameter is the path to the compiler sources.

You can 25# move it once it's built, so this mostly controls the layout of $DEST_DIR. 26DEST_ROOT="$4" 27 28# The fifth parameter is the place where the compiler will be copied once it's 29# built. 30DEST_DIR="$5" 31 32# The sixth parameter is a directory in which to place information (like 33# unstripped executables and generated source files) helpful in debugging the 34# resulting compiler. 35SYM_DIR="$6" 36 37# The seventh parameter is a yes/no that indicates whether assertions should be 38# enabled in the LLVM libs/tools. 39LLVM_ASSERTIONS="$7" 40 41# The eighth parameter is a yes/no that indicates whether this is an optimized 42# build. 43LLVM_OPTIMIZED="$8" 44 45# The nineth parameter is the version number of the submission, e.g. 1007. 46LLVM_SUBMIT_VERSION="$9" 47 48# The tenth parameter is the subversion number of the submission, e.g. 03. 49LLVM_SUBMIT_SUBVERSION="${10}" 50 51# The current working directory is where the build will happen.
