If the current machine isn't in the list, a # compiler for it will get built anyway, but won't be installed. TARGETS="$2" # The third parameter is the path to the compiler sources. There should be a # shell script named 'configure' in this directory. This script makes a copy... ORIG_SRC_DIR="$3" # The fourth parameter is the location where the LLVM will be installed. You can # move it once it's built, so this mostly controls the layout of $DEST_DIR. DEST_ROOT="$4" # The fifth parameter is the place where the compiler will be copied once it's # built. DEST_DIR="$5" # The sixth parameter is a directory in which to place information (like # unstripped executables and generated source files) helpful in debugging the # resulting compiler. SYM_DIR="$6" # The seventh parameter is a yes/no that indicates whether assertions should be # enabled in the LLVM libs/tools. LLVM_ASSERTIONS="$7" # The eighth parameter is a yes/no that indicates whether this is an optimized # build. LLVM_OPTIMIZED="$8" # The nineth parameter is the version number of the submission, e.g. 1007. LLVM_SUBMIT_VERSION="$9" # The tenth parameter is the subversion number of the submission, e.g. 03.
